Christian Winkler ist der HCI Gruppe im September 2010 beigetreten. Davor hat er als Entwickler für Onlineservices in einer Agentur gearbeitet und in der Pervasive Computing-Gruppe an der Universität Duisburg-Essen unter der Leitung von Prof. Albrecht Schmidt. In 2011 hat er eine Zeit lang als Forschungsassistent und danach als Berater für Microsoft Research in Cambridge, UK gearbeitet.
Christian hat einen B.Sc. in Medieninformatik & Design (2007) von der Universität Bielefeld und einen M.Sc. in Angew. Informatik - Systems Engineering der Universität Duisburg-Essen (2010). Der Titel seiner Masterarbeit lautete: SENSE-SATION: An Extensible Platform for the Integration of Phones into the Web (siehe Publikationen).
We present PocketThumb, a wearable touch interface for smart-eyewear that is embedded into the fabrics of the front trouser pockets. The interface is reachable from outside and inside of the pocket to allow for a combined dual-sided touch input

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 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.

We introduce the concept of an Ambient Mobile Pervasive Display (AMP-D) which is a wearable projector system that constantly projects an ambient information dis- play in front of the user. The floor display provides serendipitous access to public and personal information. The display is combined with a projected display on the user’s hand, forming a continuous interaction space that is controlled by hand gestures. The AMP-D prototype illustrates the involved challenges concerning hardware, sensing, and visualization and shows several application examples.

In this work we present SurfacePhone; a novel configuration of a projector phone which aligns the projector to project onto a physical surface to allow ad-hoc tabletop-like interaction in a mobile setup. The projection is created behind the upright standing phone and is touch and gesture-enabled. Multiple projections can be merged to create shared spaces for multi-user collaboration.

In many contexts, pen and paper are the ideal option for collecting information despite the pervasiveness of mobile devices. Reasons include the unconstrained nature of sketching or handwriting, as well as the tactility of moving a pen over a paper that supports very fine granular control of the pen. In particular in the context of hospitals, many writing and note taking tasks are still performed using pen and paper. This work presents the Penbook concept, detail specific applications in a hospital context, and present a prototype implementation of Penbook.

Projector phones, mobile phones with built-in projectors, might significantly change the way we are going to use and interact with mobile phones. This project explores the potential of combining the mobile and the projected display and further the potential of the mid-air space between them for the first time. Results from two studies with several gesture pointing techniques indicate that interacting behind the phone yields the highest performance, albeit showing a twice as high error rate. Further they show that mobile applications benefit from the projection, e.g., by overcoming the fat-finger problem on touchscreens and increasing the visibility of small objects.

Smartphones provide large amounts of personal data, functionalities, but during phone calls the phone cannot be used much beyond voice communication and does not offer support for synchronous collaboration. This is owed to the fact that first, despite the availability of alternatives, the phone is typically held at one’s ear; and second that the small mobile screen is less suited to be used with existing collaboration software. This work presents a novel in-call collaboration system that leverages projector phones as they provide a large display that can be used while holding the phone to the ear to project an interactive interface anytime and anywhere.
