- KonferenzbeitragArmTouch: The Forearm as Touchpad for VR Control(Mensch und Computer 2019 - Tagungsband, 2019) Reich, Kristin; Jäger, Elisabeth; Do, Xuan Linh; Wolf, KatrinInteracting with elements inside a virtual reality (VR) experience is usually done with a controller. However, they tend to be clunky and cumbersome to use. We designed an alternative controller that allows for a rich touch interaction. Our prototype uses the forearm for touch input in VR. The forearm is easy to find through proprioception and also displayed through the HMD. We implemented two versions, one using a touchpad mounted at the forearm and one where the input is realized through touching only the skin of one’s arm. Users can select items of different menu types and through different gestures. A user study showed that both concepts show good usability, but none of the two touch mechanisms was preferred over the other.
- KonferenzbeitragThe Gesture Authoring Space: Authoring Customised Hand Gestures for Grasping Virtual Objects in Immersive Virtual Environments(Mensch und Computer 2022 - Tagungsband, 2022) Schäfer, Alexander; Reis, Gerd; Stricker, DidierNatural user interfaces are on the rise. Manufacturers for Augmented, Virtual, and Mixed Reality head mounted displays are increasingly integrating new sensors into their consumer grade products, allowing gesture recognition without additional hardware. This offers new possibilities for bare handed interaction within virtual environments. This work proposes a hand gesture authoring tool for object specific grab gestures allowing virtual objects to be grabbed as in the real world. The presented solution uses template matching for gesture recognition and requires no technical knowledge to design and create custom tailored hand gestures. In a user study, the proposed approach is compared with the pinch gesture and the controller for grasping virtual objects. The different grasping techniques are compared in terms of accuracy, task completion time, usability, and naturalness. The study showed that gestures created with the proposed approach are perceived by users as a more natural input modality than the others.
