Visuo- & HoverHaptics - Drohnen als Haptische-Gadgets

SolKutTeR · 23. Januar 2019

Alle reden von Lieferservice mithilfe von Drohnen,..
hier ein recht interessantes Konzept von der Standford Universität HoverHaptics, um diese als Haptische-Gadgets einzusetzen.

We suggest that quadcopters can facilitate rich haptic interactions beyond force feedback by appropriating physical objects and the environment. We present HoverHaptics, an autonomous safe-to-touch quadcopter and its integration with a virtual shopping experience. HoverHaptics highlights three affordances of quadcopters that enable these rich haptic interactions: (1) dynamic positioning of passive haptics, (2) texture mapping, and (3) animating passive props. We identify inherent challenges of hovering encountered-type haptic devices, such as their limited speed, inadequate control accuracy, and safety concerns. We then detail our approach for tackling these challenges, including the use of display techniques, visuo-haptic illusions, and collision avoidance. We conclude by describing a preliminary study (n = 9) to better understand the subjective user experience when interacting with a quadcopter in virtual reality using these techniques.

Hier noch ein erster Einblick in die Visuo-Haptic Einheit, auf den Drohnen.

We utilize visuo-haptic illusions to improve the perceived performance of encountered-type haptic devices, specifically shape displays, in virtual reality. Shape displays are matrices of actuated pins that travel vertically to render physical shapes; however, they have limitations such as low resolution, small display size, and low pin speed. To address these limitations, we employ illusions such as redirection, scaling, and retargeting that take advantage of the visual dominance effect, the idea that vision often dominates when senses conflict.

Our evaluation of these techniques suggests that redirecting sloped lines with angles less than 40 degrees onto a horizontal line is an effective technique for increasing the perceived resolution of the display. Scaling up the virtual object onto the shape display by a factor less than 1.8x can also increase the perceived resolution. Finally, using vertical redirection a perceived 3x speed increase can be achieved.
