Design and manufacturing  

Robustness 

The good quality of the materials with which the glasses are made mean that this product has the possibility of lasting with use over time.  

However, there are certain precautions or indications that must be taken into account to prevent the glasses from being damaged: 

• Exposure of the optical lenses to direct sunlight for approximately 1 minute may cause permanent damage to the optical lenses, which may cause the image displayed on the device to appear yellow flecked or have dead pixels. 
• Special care must be taken to prevent the lenses from being scratched. 

• Cleaning the optical lenses of the VR goggle can be done with the microfiber cloth included in the kit or with alcohol-free disinfectant wipes. We should not clean the lenses with alcohol or other strong or abrasive cleaning solutions, as they could be damaged. 
• Cleaning the face cushion can be done with the microfiber cloth included in the kit that can be previously moistened with water or 75% isopropyl alcohol.  

Packaging 

The kit comes in a box measuring 285 x 135 x 205 mm, which contains the VR goggle and its accessories inside, which are protected by rigid foam.  

Physical/technical characteristics of the VR glasses 

• The VR goggle is brand Pico and G2 4K S model, it has a Qualcomm Snapdragon 835 CPU, a 4K LCD screen with a screen resolution of 3840 x 2160 (4K). With a refresh rate of 75Hz and 818 pixels per inch (ppi).  
• The Pico G2 4K S VR headset has its own custom layer (interface) that runs on top of the Android operating system. 
• Storage is 128GB which can be expanded with a Micro-SD card up to 256GB. 
• It has a 4GB memory. 
• The field of view is 101 degrees. 
• The weight of the glasses is approximately 280 grams. 

Physical/technical characteristics of the motion controller 

Pico brand motion controller runs on two AAA batteries.  

Its design allows you to hold it comfortably and be able to interact with any of its buttons. 

Among the buttons we have:  

• Touchpad: this button does not have any associated functionality within the Oroi applications (Wellbeing, Cognitive or Fit), but it can be used to move between the options when we are configuring the Wi-Fi network to which the glasses will connect.  
• Back button: it is used to go from the current screen to the previous screen and if we are watching a video, this button is used to exit the video.  

• Pico button: this button has the following functionalities or uses:  
  • It is used to turn on the controller (Controller off, press once).  
  • It is used to go to the main menu (Controller on, glasses on and press the Pico button once). 
  • It is used to calibrate the controller (establish the center), for this we must point the controller and the goggle in the same direction and keep this button pressed for approximately 1 second. 
  • If we press twice, it will take us to a menu where we can select some options such as screen sharing, taking screenshots or entering the settings. 

• Trigger: used to select or confirm an action.  
• Volume button: to increase the volume we must press the upper part of this button and to reduce it, we must press the lower part of the button. 
• LED: Status indicator LED: 
  • If the light stays on, it means the controller is connected with the glasses. 
  • If the light blinks about every 0.1 seconds, it means low battery. 
  • If the light flashes approximately every 0.5 seconds, it means that the controller is searching for a connection. 
  • If the light flashes approximately every 1.5 seconds, it means the firmware is being updated. 

Physical/technical characteristics of the speed sensor 

brand speed sensor GARMIN It will be used when we go to perform any exercise of the application remember fit. 

This sensor is easy to install, it should only be placed on the exercise equipment (in our case pedals, as shown in the image on the left). Bluetooth technology allows the sensor to be synced with the app remember fit.   

User interface   

Once we turn on the glasses, a suggestion will appear to activate the controller, since through it you interact with the interface of the glasses and the applications. However, it is possible to skip the activation and continue with the controls of the glasses itself. It is recommended not to skip the activation since the use of the controller is important to enjoy the applications correctly. 

After this we will see the main page, where we can access different sections such as the application menu, settings or their Store. 

The interface is quite striking, and together with the icons, it makes interaction with it intuitive. 

The language of the glasses can be changed, but it does not influence the language of the applications. 

As for the interaction with the environment, the use of a controller makes the experience easier by avoiding head movements that exist using the buttons on the glasses. On the other hand, in some cases it can be tedious, since it is possible to confuse some buttons because they do not have any type of relief, that is, they are aligned with the surface of the controller. 

The controller has buttons to select the options to increase or decrease the volume, go back and return to the main page of the glasses (Pico - Home button). These same features are offered in the glasses thanks to the buttons incorporated into it. However, in apps, option selection can only be done with the controller trigger. 

In any case, there will be the presence of a virtual pointer that will allow us to locate ourselves in the desired option or functionality. 

As we said before, OROI has three applications: Oroi Wellbeing, Oroi Cognitive and Oroi Fit, which we will access from the applications menu. 

Oroi Wellness 

This application has immersive entertainment therapies that favor the well-being and enjoyment of users, reducing anxiety, boredom or depression that the user may be suffering from. 

The content of this application consists of 360º immersive videos that are classified into sections:     

• Places 
• musical and performing arts 
• Museums and visits 
• Experience 
• Animals and nature 

After selecting any of these sections, we will view all content, being able to access the available ones or download those that we do not have. 

As for the videos, we can highlight that some have a narration corresponding to the sites visited as if it were a tourist route, this makes the use of glasses more familiar and friendly. 

Likewise, we can highlight the availability of these in various languages ​​such as Spanish, English, French and German, however, not all the videos are in these languages, that is, there are videos that are only in a specific language. 

Each user has the set of videos corresponding to their country, so that they already have these videos in the respective language, that is, the language of the content is preset. 

The quality of each video is also preset and cannot be changed through the glasses. Despite this, the sharpness of these is calibrated by a sensor that the glasses have in the space dedicated to the nose. In case of wearing masks, sharpness calibration may be difficult due to interference with the sensor. 

Oroi Cognitive 

This application is aimed at exercising cognitive functions by performing exercises that simulate everyday actions, puzzles, or memory activities. 

It also has different exercises divided into boxes, which, when placing the virtual pointer over them, will show an explanatory message associated with the activity, whose language will change depending on the one selected on the home page. 

After selecting any of the activities we will go to a new window, where we can access the different levels that each activity contains. The provision of several executable scenarios makes the use of the glasses more attractive, since it is entertaining to test the capabilities without making a task monotonous, while activating our cognitive functions in simple and friendly environments. 

The difficulty of the levels is not excessive and it is possible to carry out the activities or exercises without comprehension problems. In any case, in each activity we find an icon in the shape of a question mark, which tells us how we should execute the corresponding task or what it consists of. 

It is important to mention that the explanatory messages that appear both in the aforementioned tables and in the activities themselves are quite visible, which facilitates their reading and understanding. 

Regarding the interaction within the activities, we noticed great fluidity, that is, the signals sent from the controller are correctly captured, which means that the exercise is carried out dynamically and without any type of delay. 

Sometimes, we find that the virtual pointer is not centered, which can make it difficult to select options or execute tasks, so it will be necessary to keep the Home button pressed for a few seconds to calibrate it. 

Oroi Fit 

This application is aimed at facilitating physical exercise in the elderly. It consists of interactive videos where users will take bike rides (in real or 3D environments), or rowing activities (in real environments).  

To carry out the activities, it will be necessary to use some pedals and a movement sensor with Bluetooth connection (which fits into the pedals), which are included in the OROI kit. 

The execution of the application is similar to the previous ones and after entering the data correctly we will access the main page, where we will be able to see two options: bicycle or rowing.  

After selecting one of the scenarios that contain these last options, it is necessary to connect the sensor, which is activated after pedaling for a few seconds, and then we will go on to the route. 

It is striking that the sensor turns on with the movement of the pedals, since in some cases it can be tedious to configure and connect this type of device. In this way, it is only enough to select the device from the glasses to be able to carry out the activity. 

Within the route we have a speed meter, which allows us to check the pedaling rhythm; a distance counter, which allows us to know the route we have taken; and an icon that represents the progress of the bicycle or difficulty in rowing, which influences the way in which we must pedal (with greater or lesser speed) and that changes when pressing the selection button. 

As we can see, the interaction with the videos is based on the use of pedals, since their reproduction will depend on the perception of their movement, so that when pedaling we will advance, and if we stop pedaling, the speed will slow down until we stop.  

It should be noted that the use of the pedals and the goggles simultaneously favors the user's immersion, which, added to the landscapes, give a realistic sensation of being on a bicycle or rowing ride. 

The speed control also provides realism, taking into account the progression of the movement and the influence of the gears, avoiding considering everything in a uniform way, that is, the faster we pedal, the faster we will go, and depending on the gears, the speed will increase or decrease. will decrease for the same pedaling pace. 

It is necessary to remember that excessive use or excessive pedaling can cause dizziness. 

In this case, the controller will only be necessary to increase the speed of the bicycle or exit the video. 

User interface in the backend 

In order to enter the backend we must go to the following link http://backend.oroi.tv/ and enter our username and password.  

Sections 

Main menu: thanks to this section we can access a very complete video tutorial where it is explained in detail how to use the glasses, the applications and some recommendations. This video tutorial is approximately 50 minutes long. In addition, we will have access to a manual called "First steps with Oroi". 

Management: this section allows us to manage our sub-users. 

Products: thanks to this section we can access all the content, statistics and tutorials available for the Wellbeing, Cognitive and Fit applications. 

 Competition: this section shows the Oroi Tour championship related to the Oroi Fit application where the distances covered by all sub-users are added up. 

Downloads: In this section you will find the option to download Oroi Cast which we will talk about later. 

Oroi Cast User Interface 

What is Oroi Cast? 

Oroi Cast is a program that allows viewing the content of the glasses from the computer.  

The reproduction on a screen of the content that is reproduced in the glasses, helps the professional (doctor, nurse, caregiver, etc.) to visualize in real time the same as the patient and perform (if necessary) exercises or questions for stimulation user cognition.   

For example, if the patient is viewing the content of the Wellbeing application about Madrid, the professional can ask him if he has ever been to the site he is viewing.  

Among the languages ​​available to configure remember Cast we have: Spanish, English, French and German. It is important to mention that the language selected in the menu of remember Cast does not affect the language configured in the glasses. 

In addition, the program allows us to choose the image quality that is displayed on the computer (it does not affect the image quality of the content of the glasses).  

At the time the tests were carried out, the recommended image quality was to choose the minimum. In this way, a sufficiently good quality was achieved while reducing the delay that could exist between what the patient visualized (in the glasses) and what the user visualized when looking at the computer screen. 

However, due to an update in the app released after testing, the developers recommend setting the quality to maximum. 

Connection ways 

To establish communication between the glasses and the program, the connection can be used by connecting the USB cable (included in the kit) to any available USB port on the computer and to the USB-C charging port of the glasses.  

In addition, there is the possibility of establishing a wireless connection, for this, we must first activate the “Wireless connection” option in the program settings menu remember Cast and both the computer and the glasses must be connected to the same Wi-Fi network. 

User experience 

Most remarkable opinions of user X of the technical team  

• The experience of using prescription glasses with the VR goggle was satisfactory. The use of prescription glasses did not make any significant difference compared to the experience of the other users who were members of the technical team. 
• User X presented eye fatigue when using the VR glasses. 

Currently, the longest video available on OROI is fourteen minutes long and the shortest video is two minutes long. If a user watches only one video (average duration 6-7 minutes), the probability of eye fatigue is very low. However, there could be rare cases, where users experience eye fatigue, even though they have watched a short video. This happened to user X and could have been influenced by some prior optical condition. 

We remind you that if you suffer from sensitivity to light you can adjust the brightness of the screen and activate the eye protection mode (available in the settings menu of the VR Pico glasses), which protects your eyes from the blue light of the screen. 

• Some physical buttons on the goggle or controller were difficult to identify as the view was not focused on the physical object (the view was focused on the visual content of the goggle). User X commented that it would be interesting if these buttons had reliefs (or protruded more) to identify each button quickly while the user is wearing the VR glasses. 

It is important to mention that these physical characteristics of the VR glasses or the controller do not depend on the creators of Oroi but on the manufacturer (Pico). But it is necessary to mention it so that users take these points into account. 

To turn on/off the VR goggle it is necessary to interact with the physical buttons present on said goggle, to avoid the recognition problem, we recommend interacting with the button before putting on the goggle (to turn it on) and after removing the goggle in case you want to turn it off . 

• The content was entertaining, educational and did not affect their perception of reality. 

Most remarkable opinions of the user AND the technical team 

• The interface is friendly and not stressful. 
• As for the interaction with the applications, no complications were found, except for some confusion with the buttons to go back and to return to the main menu of the glasses. 
• After prolonged use it is possible to suffer a slight dizziness. It is worth mentioning that suffering from this type of problem depends on the person, and in this case it occurred in the time that elapses from the opening of one of the applications to the end of one of the videos, we calculate that approximately 10 minutes. 
• In terms of content, the existence of a wide variety of videos, activities and landscapes is striking. As well as the narration in some Oroi Wellbeing videos, the activity levels in Oroi Cognitive and the interaction through the pedals in Oroi Fit. 

Recommendations for users: 

• It is recommended that the user wear the goggle when seated. 
• Use a suitable volume, high volume for a long time may damage your hearing. 

Remember that, in case of using headphones or headphones, the WHO recommends following the 60-60 rule, which consists of avoiding the use of headphones for more than 60 minutes and for more than 60% of their power. 

• Prolonged use of the glasses can cause dizziness or eye fatigue, therefore, the manufacturer recommends taking a break every 30 minutes of continuous interaction with the content of the glasses. 
• If you wear prescription glasses, be very careful when putting on or taking off the VR goggle. It is recommended that you first support the VR goggle to your nose (1), adjust it, then put on the counterweight or rear head pad (2), and finally adjust the straps if necessary.

Technical performance 

Reliability 

During the testing time, the goggle and controller worked fine when users interacted with them. However, some of the applications remember They had some drawbacks: 

• At the time of testing in the application remember Fit, during the course of the rides in the fictional 3D scenarios, a point was reached where the ride stopped despite the movement of the pedals. However, it was observed how the speed increased or decreased depending on the pedalling, and how the distance traveled increased with the bicycle still stationary. 

It is important to mention that, after an update of the application, released outside the testing period, the Oroi developers informed us that this problem was solved. 

• In the app remember Cognitive, exactly in the exercise with the “home” theme, the problem we found is that it did not load. Because of this, we contacted the creators of remember and we were informed that this was due to a failed update but that another update would be coming soon to fix this issue. 

Performance  

The response time when pressing a button on the controller or the glasses and executing the functionality associated with that action is immediate. 

The download time of the contents of the Oroi applications is affected by the intensity of the Wi-Fi signal that we have and by the size of the content.  

Consumption 

We must not forget that the battery life of the glasses will be affected by the time we use it and the functionalities with which we interact. The battery lasts approximately 3 hours with continuous use (rough estimate provided by TECSOS technical team). 

In long sessions it is recommended to leave the glasses in sleep mode (when not used for a short time), which will be activated after not detecting the presence of a user for a certain time so that it does not consume battery power unnecessarily. However, in general terms, the glasses have a long duration.  

Safety 

To obtain information about the security of your data, we recommend that you carefully read the Privacy Policy and the Data Protection Policy that it provides. remember publicly at the following links:

Accessibility     

Despite the fact that it is a solution aimed at the group of older people, we have seen that its use can be extended to a larger range of people. 

Among the accessibility features we can highlight: 

• It has a simple and intuitive interface, which facilitates the perception of information and understanding of the environment. 
• There are some explanatory text messages about the activities, as in the case of Oroi Cognitive. In Oroi Wellbeing, in addition to text messages, there is also a voice message that together provides information about the site being visited and makes it easier to understand the environment.
• Oroi Cognitive exercises are classified by levels, which allows you to perform exercises adapted to the needs of each user. 
• The controller facilitates user interaction with Oroi applications. However, people with motor difficulties in the hands or arms as a result of cerebral palsy, spinal cord injury, multiple sclerosis, among others, who cannot hold the controller, press the buttons or make movements with the controller, will not be able to interact with the Oroi applications. However, there is a way in which this group can enjoy the experience of using Oroi Wellbeing and Oroi Fit, with the help of a caregiver, nurse, etc. For this, Oroi Cast would have to be used to visualize the same as the user in real time and the caretaker must manipulate the controller. 
• People with reduced or no mobility, illnesses, injuries, among others, that affect the movement of their legs cannot enjoy the exercises of the Oroi Fit application. 
• Unfortunately, people with reduced or no vision cannot enjoy the use of this solution because they would not receive the visual information provided by Oroi's content.    

Conclusions  

There is no doubt that this is a powerful virtual reality solution that many older people can benefit from, covering some of their needs such as entertainment, cognitive stimulation and physical stimulation. 

After thoroughly analyzing this solution, we found the following highlights and points for improvement. 

Highlights 

• The Wi-Fi connection will only serve us to download the new contents of remember, therefore, if we have content available in the glasses, it will work perfectly without relying on a Wi-Fi connection.  
• The glasses have an “Eye Protection Mode”, which protects your eyes from the blue light of the screen. 
• The controller makes it easy for the user to interact with the Oroi interface. 
• It contains three applications aimed at different fields of well-being: Oroi Wellbeing, Oroi Cognitive, Oroi Fit, 
• In the three applications we can say that the interface is simple and intuitive. 
• They have a wide variety of videos, exercises or activities, which make the use of the glasses not monotonous. 
• The contents of the different applications are available in several languages: Spanish, English, French, Portuguese, Italian, German, Basque, Catalan and Finnish. 
• Thanks to remember Cast, the professional will be able to visualize in real time the same as the patient and perform exercises or questions for the cognitive stimulation of the patient.   
• El backend de remember, allows us to access tutorials, sub-user management, display of statistics (individual or group) and activity proposals. 
• The possibility of creating sub-users allows you to select configurations and exercises suited to the different needs of the user. 
• There is an initial training offered by Oroi's specialized staff in which we can resolve all our doubts. 

 Improvement points 

• Using the controller may be more comfortable than using the buttons on the glasses. However, according to the opinions gathered by the technical team in the tests carried out, it was concluded that it would be interesting for the controller buttons to have some kind of relief inside each button or to protrude a little more from the surface of the controller. , to differentiate them when we have the glasses on (if we have the glasses on, our view will be directed to the glasses interface and not to the controller, which can cause some users to get confused when pressing a specific button).  
• Controller labels are only available in English, it would be helpful to make it available in more languages ​​to benefit more users or not create confusion for users who speak another language.    
• In the 3D environments of Oroi Fit there is an error where the bike stops despite continuing to pedal, the same happens in the rowing section.  

According to the Oroi developers, this problem was solved in the latest released update, unfortunately the technical team could not confirm it since this correction was made outside the testing period. 

• In Oroi Cognitive, there is an activity that cannot be accessed. (Problem being corrected). 

We remind you that changes in any physical characteristic of the VR goggle depend on the manufacturer (Pico). Even so, these aspects also determine the product and it is interesting to mention them so that users take them into account. 

The same goes for the languages ​​that are listed in the device configuration, as in the case of the language in which the driver labels are found, mentioned earlier.
