Most data-intensive operations for multimedia applications such as image processing, vision, and 3D graphics require high external memory bandwidth. In augmented-reality (AR) processors [1], both 3D graphics and vision operations are required, so memory bandwidth becomes even more critical. In [1], however, memory bandwidth is not considered, floating-point processing is not supported, and there is...
The objective of this research is to propose and design a compact tactile display module and verify its performance in a pen-like haptic interface, particularly on the touch screen. A small, safe, silent and light tactile display module with low power dissipation has been built. Based on this module, we present the Ubi-Pen, a pen-like haptic interface providing texture and vibration stimuli. Preliminary...
