The frame rate of existing stereo cameras is not enough to track quick hand or finger actions. It also requires lots of computational cost to find correspondence between stereo images to compute distance. The recently commercialized 3D position sensors such as TOF cameras or Leap Motion needs strong illumination to ensure sufficient optical energy for the high frame rate sensing. To overcome these...
Simulator sickness is an issue in virtual reality environments. In a virtual world, sensory conflict between visual sensation and self-motion perception occurs readily. Contradiction between visual and vestibular sensation is a dominant cause of motion sickness. Vection is a visually evoked illusion of self-motion. Vection occurs when a stationary human experiences locomotor stimulation over a wider...
This paper presents a simple but effective way of enhancing tactile stimulus by a mechanism with springs to preserve elastic energies charged in a prior energy-charging phase and discharge them to enhance the force to hit a finger in the stimulating phase. With this mechanism, a small and light stimulator attached to the fingertip is developed and demonstrated to generate the tactile feedback strong...
To improve single-handed operation of mobile devices, rear touch panel operation to control commands and facial feature detection to control cursor position are proposed. Operational control is achieved through finger chord gestures on a rear touch panel, and nose movement is used to control cursor movement. Zooming is achieved by detecting the apparent distance between the left and right eyes in...
