HapticHead - Around-the-head tactile display

HapticHead is a novel around-the-head tactile display which can be used in a variety of applications such as guidance utilizing moving tactile cues, important tactile notifications or immersive Virtual- and Augmented Reality experiences. Developed by the Human-Computer Interaction group at the University of Hannover, HapticHead is under active development and evaluation as of 2018.

Guidance

HapticHead can generate moving tactile cues which allow intuitive spatial awareness of nearby virtual or real objects, positions or orientations. This also allows navigating visually impaired people which is an active topic of research.

Immersion

Applications in Virtual- and Augmented Reality aim to immerse the user in a fully-fletched experience in which a HapticHead display can play a major role in by letting the user feel virtual snowflakes, shockwaves or objects close to their head.

Notifications

Getting a directional tactile notification directly on the surface of the head in the event of emergency may help save precious time. This kind of notification cannot be missed and is interpreted intuitively, giving the user just that little bit of extra time to react.

A high level of presence is an important aspect of immersive virtual reality applications. However, presence is difficult to achieve as it depends on the individual user, immersion capabilities of the system (visual, auditory, and tactile) and the concrete application. We use a vibrotactile grid around the head in order to further increase the level of presence users feel in virtual reality scenes. In a between-groups comparison study the vibrotactile group scored significantly higher in a standardized presence questionnaire compared to the baseline of no tactile feedback. This suggests the proposed prototype as an additional tool to increase the level of presence users feel in virtual reality scenes.
