David Dobbelstein, M.Sc.

David Dobbelstein joined the HCI group in October 2011. During his studies he was an intern at Daimler AG and at Nokia. 

David holds a M. Sc. in Applied Computer Science - Systems Engineering (2014) from University of Duisburg-Essen. He wrote his Master thesis in cooperation with Nokia Research in Sunnyvale (USA). The title of the master thesis was: Investigating Interaction Performance on a Novel Handheld Near-Eye Display.

    Belt: An Unobtrusive Touch Input Device for Head-worn Displays

    Belt is a novel unobtrusive input device for wearable displays that incorporates a touch surface encircling the user’s hip. The wide input space is leveraged for a horizontal spatial mapping of quickly accessible information and applications. We discuss social implications and interaction capabilities for unobtrusive touch input and present our hardware implementation and a set of applications that benefit from the quick access time. In a qual- itative user study with 14 participants we found out that for short interactions (2-4 seconds), most of the surface area is considered as appropriate input space, while for longer interactions (up to 10 seconds), the front areas above the trouser pockets are preferred.

  • FaceTouch: Touch Interaction for Mobile Virtual Reality

    FaceTouch: Touch Interaction for Mobile Virtual Reality

    We present FaceTouch, a mobile Virtual Reality (VR) headmounted display (HMD) that leverages the backside as a touch-sensitive surface. FaceTouch allows the user to point at and select virtual content inside their field-of-view by touching the corresponding location at the backside of the HMD utilizing their sense of proprioception. This allows for a rich interaction (e.g. gestures) in mobile and nomadic scenarios without having to carry additional accessories (e.g. gamepad). We built a prototype of FaceTouch and present interaction techniques and three example applications that leverage the FaceTouch design space.

    Glass Unlock: Enhancing Security of Smartphone Unlocking through Leveraging a Private Near-eye Display

    Glass Unlock is a novel concept using smart glasses for smartphone unlocking, which is theoretically secure against smudge attacks, shoulder-surfing, and camera attacks. By introducing an additional temporary secret like the layout of digits that is only shown on the private near-eye display, attackers cannot make sense of the observed input on the almost empty phone screen.
