Spatial Interaction with Haptic Holograms

چکیده
We present a comprehensive report of our work in the design and implementation of systems that combine holog-raphy with haptic feedback. Two separate holo-haptic systems are described. First, we describe a static system wherein a user can see a free-standing static holographic image and inspect its shape using a force-feedback stylus. In the second system, visual display is provided by a dynamic holographic video system, and the user can modify the geometry of the image in near real-time. We also suggest a preliminary set of guidelines for presenting physically believable multimodal simulations in coinci-dent visual-haptic workspaces.

the feel of virtual information. Extant systems with both visual and haptic output usually employ an spatially offset workspace configuration in which the hand's operation of the haptic device is in a space separate from where the eyes are looking. In contrast, our spatially coincident workspace permits the hand, feeling due forces, to be part of the visual display. Visual sensing, haptic sensi...

We describe the implementation of a system which enables a user to interact with and modify an electronic holographic image using a force-feedback device. The force-feedback (or haptic) device is capable of sensing and reporting the 3D position of its hand-held stylus and displaying appropriate forces to the user. Thus, a user can feel and modify algorithmically specified shapes in the haptic w...
متن کاملHaptic target acquisition to enable spatial gestures in nonvisual displays
Nonvisual natural user interfaces can facilitate gesture-based interaction without having to rely on a display, which may significantly increase available interaction space on mobile devices, where screen real estate is limited. Interacting with invisible objects is challenging though, as such techniques don’t provide any spatial feedback but rely entirely on the users’ visuospatial memory. Thi...
متن کاملThe effect of non-informative spatial sounds on haptic scene recognition
Previous studies found that performance in tactile or haptic spatial tasks improved when non-informative visual information was available, suggesting that vision provides a precise spatial frame to which tactile information is referred. Here, we explored whether another intrinsically spatial modality, audition, can also affect haptic recognition. In all experiments, blindfolded participants fir...
