Headset Configuration
With the headset on your head, switched off and the controllers attached to your wrists ensure you are seated comfortably on a regular chair rather than an armchair. Straighten your back and look forward.
Switch on the headset with a long press of the power button. It is important to configure the headset for a stationary boundary.
You may be prompted to Create a boundary. If this occurs, Select STATIONARY BOUNDARY
Alternatively, if you are returning to the same seated position from a prior session, you may be asked to confirm boundary. As this is probably the first time you have followed these instructions, it would be recommended to select CREATE NEW BOUNDARY
If however, you are prompted to draw a Roomscale boundary, it is very important to select SWITCH TO STATIONARY BOUNDARY
STEP 2. You will be prompted to confirm the floor level. You can do this by reaching over and touching the floor with one of your hand controllers. Alternatively, you may use the thumbstick on either controller to move the visible grid to floor level.
When you are happy that you have established the level of your floor, Select the Confirm button.
You will arrive at the main oculus menu. Select Equal-Eyes from "Unknown Sources" and you will arrive at the Main Menu.
Note: If you are unfamiliar with starting sideloaded apps, please visit the end of this page.
The Setup Menu
At the Equal-Eyes main menu, select SETUP
You will be presented with a Target and three instruction panels. At this point, it is important to ensure that the three geometry settings are initially reset to zero.
The Rotation is know as the Z-Plane. The axis of this plane is an imaginary line coming out of your eye to the horizon. For most users this should be reset to Zero by pressing the Zero Rotation Button.
The H-Plane is the has an axis running from the ceiling to the floor. Rotation on this plane will need to be adjusted should you have Exotropia or Esotropia. Initially, set this to Zero by pressing the Zero H-Plane Button.
The V-Plane has an axis running from Left to Right. Rotation on this plane will need to be adjusted for the rarer condition of Hypertropia or Hypotropia. Again, initially set this to Zero by pressing the Zero V-Plane Button.
Finally, if you have a weak eye, Tick either the Left or Right Check boxes. If you don't have a weak eye, then leave the Left Eye Checked as shown in the above image.
Should at any time, the geometry go completely astray. Pressing all three buttons will return you to factory settings
At this stage Press the A button on the right hand controller to store the settings and return to the main menu.
You may re-enter Setup from the Main Menu to proceed with the User Calibration Below.
User Calibration
On starting Equal-Eyes you will be presented with an outdoor scene and a menu. If the menu is not directly in-front of you, press the and hold Oculus button on your right hand controller. This will present you with an option to centre the scene. Do so now, if required.
Once the menu is in view, Select the Setup option. This will present you with a Large Cross Hair Style Target
Below the target are three panels. The one to the right presents you with a pair of check boxes that must be ticked in order to configure the eye that needs to be targeted in the exercises.
Use the thumbstick on the right hand controller to overlay the green ball of the weak eye over that of the strong eye.
Once aligned on this horizontal plane, you may see that the green ball is also misaligned on the vertical plane. For example the green ball in one eye may be hovering above the green ball in the other.
To correct this error, using the same Right Hand thumbstick, move the ball up or down until the balls are directly on top of each other.
Finally, it's time to observe the large cross-hair under the green ball. It may be apparent that the cross hair appears slightly rotated in one eye with respect to the other. This error can be removed using the thumbstick on the Left Hand controller. Move the thumbstick left or right to try and achieve the cross-hair rotational alignment.
After doing this you may find that the ball tends to wander in one eye. This is quite normal. The brain is not used to the images being aligned and will constantly try to move it out of alignment. Don't be frustrated by this. The effect will disappear over time.
If you find that alignment is hard to achieve because the brain is trying to obscure your weak eye, this can be overcome by reducing the intensity and quality of image in your good eye.
Using the Left Hand controllers X and Y buttons reduce the brightness of the good eye so that the weak eye is force to work harder. If this isn't helping try to reduce the focus of the good eye by clicking the Right-Hand thumbstick (Pressing the thumbstick into the controller until a tactile click is felt). The focusing can be restored by pressing the Left-Hand thumbstick in the same manner. Generally, a combination of the brightness and focus will provide an optimum condition to aid the alignment of both the ball and cross-hairs.
Once you are reasonably happy that the images for the weak eye have adequately overlaid the strong eye, take note of the corrective errors shown in the Right Hand Panel below the Target.
Finally! And this is an important step. Press the A button on the right hand controller. This will store "Your" configuration into the headset.
Very Important - Seating Position and Posture
Being correctly seated is very important when using Equal-Eyes. This is particularly important if you suffer with a large turn in your eyes. This is applicable to both Exotropia and Esotropia. The effect is an unusual twist in the images between the Left and Right Eyes. This twist, if evident can severely impact the training efficacy.
It is very important that your head is not tilted at an up or down position. A typical example of unintended head tilt up can happen if you are sat on a low couch. Because of the spacial awareness of the Quest, Sitting on a low couch can force you to tilt your head up to view the scenes. This effect is very noticeable in the Dark Room.
Below is an important video describing how poor seating height can dramatically affect the quality of therapy you receive from the application and the mechanics behind it. Please watch.
