The Android device provided in the kit will come pre-installed with the AdHawk applications, no installation is required. It is recommended that you do not connect the Android device to the internet and no system updates should be performed.
A quick start or autotune operation is required each time the user puts on the glasses in order to center the scan region for each user. The quick start operation will also perform a single point calibration or recenter a previously saved calibration, if available.
A device calibration (using the calibration fixture) is not currently supported on Android. The device should be calibrated on a PC at least once a week. We recommend calibrating the device once at the beginning of each day of use.
There will be three applications installed: (1) AdHawk BackendService, (2) AdHawkHub, and (3) AdHawk Video Service, as shown below. Launch AdHawk Hub to calibrate, record, and replay eye-tracking sessions. AdHawk Backend Service and AdHawk Video Service run in the background and are automatically launched with the AdHawk Hub. See AppInstallation for instructions. Be sure to provide the requested permissions to these services when prompted.
Whenever the AdHawk Hub is launched and/or the MindLink glasses are connected to the Android, a couple pop-ups will appear in regard to allowing permission for usage of AdHawk Backend Service and AdHawk Video Service. Please click 'allow' on all pop-ups.
When selecting a nosepiece, run 'Auto-tune' to see if the selected nosepiece is the best fit for the user. If it is NOT the right-fit nosepiece, 'Auto-tune' will fail with a pop-up 'Auto-tune Failed'. Try again with a different nosepiece until 'Auto-tune Complete'. Look at Auto-tune under How-to's for instructions.
Before performing a calibration, please ensure that the appropriate profile has been selected or else the software will not allow the user to do so.
By default the calibration is set to 5 points. For higher accuracy, or a faster calibration this can be changed to 1, 3, 5 or 9, in the settings tab.
