Dennis Wolf, M.Sc.
From 2010 to 2016, Dennis Wolf was a student at Ulm University. In 2016, he became a PhD student in the Human-Computer-Interaction group.
Dennis acquired a B.Sc. (2013) and an M.Sc. in media infomatics (2016) at Ulm univesity, repectively. The title of his master theses was: "OctiCam: An Immersive and Mobile Video Communication System for Relatives and Children".
In the winter of 2016, Dennis spend 3 months at Cambridge university, UK doing an internship in the Intelligent Interactive Systems Group lead by Dr Per Ola Kristensson. This lead to a collaboration on two still ongoing projects.
- Mobile Devices
- Virtual Reality
- Touch Interaction
- Ubiquitous Computing
Since 360 degree movies are a fairly new medium, creators are facing several challenges such as controlling the attention of a user. In traditional movies this is done by applying cuts and tracking shots which is not possible or advisable in VR since rotating the virtual scene in front of the user’s eyes will lead to simulator sickness. One of the reasons this effect occurs is when the physical movement (measured by the vestibular system) and the visual movement are not coherent.
GyroVR uses head worn flywheels designed to render inertia in Virtual Reality (VR). Motions such as flying, diving or floating in outer space generate kinesthetic forces onto our body which impede movement and are currently not represented in VR. GyroVR simulates those kinesthetic forces by attaching flywheels to the users head which leverage the gyroscopic effect of resistance when changing the spinning axis of rotation.
OctiCam is a mobile and child-friendly device that consists of a stuffed toy octopus on the outside and a communication proxy on the inside. Relying only on two squeeze buttons in the tentacles, we simplied the interaction with OctiCam to a child-friendly level. A build-in microphone and speaker allows audio chats while a build-in camera streams a 360 degree video using a fish-eye lens.
This project deals with a novel multi-screen interactive TV setup (smarTVision) and its enhancement through Companion-Technology. Due to their flexibility and the variety of interaction options, such multi-screen scenarios are hardly intuitive for the user. While research known so far focuses on technology and features, the user itself is often not considered adequately. Companion-Technology has the potential of making such interfaces really user-friendly. Building upon smarTVision, it’s extension via concepts of Companion-Technology is envisioned. This combination represents a versatile test bed that not only can be used for evaluating usefulness of Companion-Technology in a TV scenario, but can also serve to evaluate Companion-Systems in general.
ColorSnakes is an authentication mechanism based solely on software modification which provides protection against shoulder surfing and to some degree to video attacks. A ColorSnakes PIN consists of a starting colored digit and is followed by four consecutive digits. From the starting colored digit, users indirectly draw a path (selection path) consisting of their PIN. The input path can be drawn anywhere on the grid.
