Dr. rer. nat. Simon Voelker
Researcher / Akademischer Rat
I am a researcher (Akademischer Rat) in HCI (Human Computer Interaction) at the Media Computing at RWTH Aachen University (Germany), headed by Prof. Jan Borchers. My research is about interaction theories, techniques, and systems in areas ubiquitous computing environments, multitouch tables, interactive surfaces, and tangible user interfaces.
I did my Diplom (2010) and my Ph.D (2016) at the Media Computing at RWTH Aachen University.
My Ph.D thesis focussed on bringing the benefits of multi-touch input to desktop workspaces by overcoming the ergonomic challenges of large multi-touch surfaces and the lack of haptic feedback when interacting with these surfaces.
For more details, take a look at my thesis: Towards Interactive Desk Workspaces
I am also the coordinator of the board of examiners of the computer science department at RWTH Aachen University.
If you have any questions regarding the board of examiners please contact me via the online form of the computer science department.
|Knobology Revisited: A Comparison of User Performance between Tangible and Virtual Rotary Knobs: We present an experimental comparison of tangible rotary knobs and touch-based virtual knobs in three output conditions: eyes-on, eyes-free, and peripheral. Twenty participants completed a simple rotation task on a interactive surface with four different input techniques (two tangibles and two virtual touch widgets) in the three output conditions, re- presenting the distance from the locus of attention. We found that users were in average 20% faster using tangible knobs than using the virtual knobs. We found that tangible knobs retains performance even if they are not in the locus of attention of the users. We provide four recommendations of suitable choosing knobs based on tasks and design constraints. (read more)|

|PERCs: Persistently Trackable Tangibles on Capacitive Multi-Touch Displays: PERCs use the touch probing signal from capacitive touch screens to determine whether the tangibles are on- or off-screen. This allows robust capacitive tangible widgets regardless of being touched. (read more)|

|Combining Direct and Indirect Touch Input for Interactive Workspaces using Gaze Input: Interactive workspaces combine horizontal and vertical touch surfaces into a single digital workspace.However, direct interaction on the vertical surface is cumbersome. To overcome these problems, indirect touch systems use the horizontal touch surface into an input devices that allows manipulation of objects on the vertical display. If the horizontal touch surface also acts as a display, however, it becomes necessary to distinguish which screen is currently in use by providing a switching mode. In three studies we investigate the use of gaze tracking to perform these mode switches. (read more)|

|An Interaction Model for Grasp-Aware Tangibles on Interactive Surfaces: Tangibles on interactive surfaces enable users to physically manipulate digital content by placing, manipulating, or removing a tangible object. However, the information whether and how a user grasps these objects has not been mapped out for tangibles on interactive surfaces so far. Based on Buxton’s Three-State Model for graphical input, this paer present an interaction model that describes input on tangibles that are aware of the user’s grasp. (read more)|

|Passive Untouched Capacitive Widgets (PUCs) are simple physical widgets the can be detected by an unmodified capacitive touch screen without being touched by a user. They can be used on most existing projected-capacitive displays. (read more)|

|Indirect Touch is a multitouch system in which users indirectly manipulate objects on the vertical screen by with touches on the horizontal screen. This interaction improves ergonomics of interactions over an extended period by reducing gorilla arm (vertical screen) and stiff neck (horizontal screen). (read more)|
