Assistive Touch and other operating aids

The Skyle Eyetracker uses the "Assistive Touch" functionality of the iOS 13. This functionality provides a pointer that can be controlled with the eyes. A fixation on a specific viewpoint executes selected actions.

Please follow the steps below carefully.

Activate Assistive Touch

When Assistive Touch is turned on, an icon appears on the screen, whose menu makes various functionalities accessible.

EN: Settings -> Accessibility -> Touch -> AssistiveTouch -> AssistiveTouch enable

EN: Settings -> Accessibility -> Touch -> AssistiveTouch -> AssistiveTouch enable

Optional: This menu can then be customized for the user:

EN: Settings -> Controls -> Tap -> AssistiveTouch -> Customize Main Menu

EN: Settings -> Accessibility -> Touch -> AssistiveTouch -> Customise Top-Level Menu

Setting mouse speed

The mouse speed must be set to the minimum value

EN: Settings -> Controls -> Tap -> AssistiveTouch -> Pointer Movement

EN: Settings -> Accessibility -> Touch -> AssistiveTouch -> Trackingspeed

Switch on and configure residence control or Dwell Control

The residence control (1) or the Dwell Control we use to perform actions. If a location on the iPad is fixed for a specified time (3), a selected action is performed. By default, this is equivalent to a simple click or a tap. A fixation is aborted when the cursor or the point of view shifts. Since this can happen during eye tracking due to various influences, the movement tolerance (2) can be adjusted so that fixations are not unintentionally aborted.

  1. EN: Settings -> Accessibility -> Touch -> AssistiveTouch -> Enable
    Dwell Control: Settings -> Accessibility -> Touch -> AssistiveTouch -> Dwell Control
  1. EN: Settings -> Accessibility -> Touch -> AssistiveTouch -> Increase movement tolerance at will
    EN: Settings -> Accessibility -> Touch -> AssistiveTouch -> Movement Tolerance
  1. EN: Settings ->Controls -> Tap -> AssistiveTouch -> Adjust seconds of dwell at will EN: Settings -> Accessibi
    lity -> Accessibility -> Touch -> AssistiveTouch -> Seconds Seconds

Create user-specific gestures

In the AssistiveTouch menu, custom Select gestures. These can be used to make tablet-standard gestures, such as scrolling, swiping or pinching. A new gesture is created by a desired movement of the finger is recorded on the tablet. This gestures are then stored in the AssistiveTouch menu under the "Own" (Custom).

EN: Settings -> Accessibility -> Touch -> AssistiveTouch -> Custom Gestures -> Create New Gesture…

To better match icons on the desktop, you can adjust the screen size accordingly. This step is optional.

EN: Settings -> Home Screen & Dock -> Set App Icons to "Greater"
EN:Settings -> Home Screen & Dock -> App Icons

EN: Settings -> Display & Brightness -> Display -> Enlarged

EN: Settings -> Display & Brightness -> Display Zoom -> View -> Zoomed

Connecting the Eyetracker

The eye tracker is connected to the iPad with the supplied cable. The USB-C end leads to the iPad – the micro-USB end is connected to the eye tracker. An additional connection is not required.

Please note: We would like to point out that we cannot guarantee the functionality of the eye tracker when using a HUB.

The eye control can take up to 30 seconds to start. If the infrared diodes are permanently on, the device can be used.

Follow the settings in the "Assistive Touch" chapter to enable iPad control

Use of eye control

If the eye tracker is ready for use and the red LEDs are illuminated throughout, eye movements are implemented in mouse positions.

It is important that the eye tracker internal camera can capture your eyes. To do this, you can either use the video stream in the "Skyle" app, or you can adjust the eye control so that you can see the reflection of your eyes in the lens of the eye tracker. The optimal distance between eye control and user is about 60 cm.

Web app

Skyle eye control for iPad can be controlled without any installation effort. To do this, visit the skyle.local website in the browser. There you will find the possibility to perform a new calibration, to install an update, or even to display a video stream of the eye control, so that the eye control can be better positioned.

The stream can be viewed directly on the home page. As soon as you press "Start", the LEDs go out for a short moment. if the LEDs are reloaded, reload the home page.

Note: Use the video stream only to help you position it appropriately. Turn off the video stream for permanent operation.


Calibration can be performed before use. Each user has different features in mind. Be it the size of the pupil, a corneal curvature or even an eye muscle balance disorder. These characteristics influence the accuracy of the point of view calculation and must therefore be considered by calibration.

Calibration can be started differently.

  • Web app
  • Button on the back (not available for every model)

If there is a button on the back of the eye control, it can be held for two seconds to start a calibration. If the button is pressed, only the 9 point calibration can be performed.

There are two sub-items in the web app. "Start EyeTracking" starts the viewpoint tracking as long as it has not yet started. If no calibration has been saved, a new calibration is started. The "Recalibrate" button can be used to perform a simple calibration.

Update & Version

If a new update exists or is sent to you by us, you can upload the update to this page. Please note: Only include updates that we provide to you for your eye control.

If you need an update, please let us know the serial number of the eye control, which is also displayed on this page. An update is not compatible with other eye controls in the series and, in the worst case, will cause eye control to stop working.

Pause the cursor

There may be times when a viewpoint tracking is undesirable. For example, if you wanted to watch a movie, the cursor would move with your eyes. To temporarily turn off the viewpoint tracking, look at the eye control for a few seconds until the cursor stops moving.

To re-enable point-of-view tracking, repeat the above operation.
