How the Mobile Testing Accessory works
The mobile device is attached to the Device Holder using a sticky pad. The arm and base are used to support and stabilize
the Device Holder for better data quality. The Device Holder is attached to the arm using the Magnetic Plate. The Pro Nano
eye tracker sits on the Device Holder and is positioned 5 cm behind the device screen for optimal eye tracking. The Screen
Capture device is connected to the mobile device and to the computer and captures what’s on the device screen. This
makes it possible to then use Tobii
Pro Lab or other analytical software to merge the participant’s gaze (where the partici-
pant looks) and what is shown on the device screen. In this way, UX researchers and others can analyze and understand
the user’s experience on a mobile device.
