    Accuracy of a Low-Cost 3D-printed Head-Mounted Eye Tracker
    (Mensch und Computer 2015 – Proceedings, 2015) Schwind, Valentin; Pohl, Norman; Bader, Patrick
    This contribution presents a mobile modular low-cost open source 3D printed eye tracking prototype, equipped with two off-the-shelf webcams. We compared the accuracy with two state-of-the-art commercial remote eye trackers. In order to verify the benefit of head stabilization, the devices have been tested with and without a chin rest. Experiments have been conducted to determine the feasibility of an open source system and the field of application for this kind of eye tracking device in the low-cost price segment. This opens new use cases and possibilities for indoor and outdoor usability studies and offers new opportunities to apply eye tracking on mobile devices.

    Remote Drawing on Vertical Surfaces with a Self-Actuated Display
    (Mensch und Computer 2015 – Proceedings, 2015) Bader, Patrick; Pohl, Norman; Schwind, Valentin; Henze, Niels; Wolf, Katrin; Schneegass, Stefan; Schmidt, Albrecht
    Today, most digital devices are either stationary, often placed on horizontal surfaces like tables, or so-called mobile devices which are carried around by the user. In this demonstration we showcase our ongoing work on a novel type of self-actuated display. It can be placed on walls, or whiteboards and other arbitrarily oriented surfaces like ceilings. It is equipped with a whiteboard marker which allows the device to draw on surfaces it is attached to. In this work, we demonstrate the device's capabilities using an interactive scenario in which users are able to remotely control the self-actuated display to draw lines on a whiteboard. They control the device either by using their own smart phone or a provided tablet computer.
