Driving System of Diminished Haptics: Transformation of Real-World Textures
نویسندگان
چکیده
In this study, we developed a portable driving system for Diminished Haptics that transforms the haptic textures of real materials by ultrasonic vibration based on a squeeze film effect. A real material is attached on the display area (a square area with 30-mm sides) and its haptic texture is reduced. However, the vibration amplitude is decreased due to a shift of resonance frequency when a user’s finger contacts with the haptic display. Thus, a resonance frequency tracing system in the driving system plays an important role to maintain the vibration amplitude. In this paper, we focus on the details of the resonance frequency tracing system and the effect of the system is evaluated.

متن کاملTexture Overlay onto Deformable Surface Using Geometric Transformation
We propose a system that overlays textures onto the arbitrary deformable surface of an object in real time using HMD. In this system, we select a book as the object and documents as the textures. Such overlaying of textures is achieved by rendering warped textures onto a surface which is projected onto an HMD image using some geometric transformations. We assume that the surface of an object co...

In this paper, the main objective is ergonomics evaluation of automobile’s dashboard to devise suitable designs based on textures and patterns. Undoubtedly appropriated dashboards' design based on textures might be ended to more driving safety, in which the tactile-real and visualimplied texture of a surface should be considered. In this study, data was gathered by in-depth observa...

THE number of daily human computer interactions with consumer devices is increasing at a staggering rate. Just considering text messaging in the United States alone, more than a trillion text messages have been sent in the last year (CTIA Semi-Annual survey October 2011). The fundamental means of interacting with our digital environment are through video, audio, and haptics, and the sense of to...

Haptic virtual environments (VEs) are computer-generated environments within which human users can touch, feel, and manipulate virtual objects in real time through force or tactile feedback. Integration of force-feedback into VEs with graphical and auditory displays is expected to have many applications in the area of medical training, CAD/CAM, entertainment, graphic arts, and education. The de...
