A method for reproducing apparent continuous depth in a stereoscopic display using “Depth‐Fused 3D” technology

— A new method that can present fine depth increments in a stereoscopic display is proposed. In typical stereoscopic displays, depth can be presented by binocular disparity, but binocular disparity of less than one pixel cannot be displayed because, in general, electronic displays have discrete pixels. We combined binocular disparity and modulation of the edge luminance in DFD (depth-fused 3D) displays. In an experiment, the perceived depth could be continuously changed by modulating the edge luminance only. Therefore, continuous depth can be produced by combining binocular disparity and modulation of edge luminance distribution.

Edge-Based Depth-Fused 3D Display

We propose a new type of depth-fused 3D (DFD) display, which employs fusion between a shape and its edge. By changing the luminance ratio between these two images, perceived depth change can be successfully obtained.

Detection of tangential force for a touch panel using shear deformation of the gel

Many capacitive touch panels detect the position and contact area of the user finger, and can estimate the vertical force from the change in the contact area. However, they cannot detect and measure the tangential force. This research aims to enable the measurement of tangential force using a gel layer, which deforms when a tangential force is applied. By measuring the finger motion of the user, we can estimate tangential force from the gel spring ratio. Using this input method, any part of the touch panel surface becomes a joystick, or virtual objects can be modeled by deforming them with the fingers.

The Effect of Frequency Shifting on Audio–Tactile Conversion for Enriching Musical Experience

We have applied a frequency-shifting method, which was proposed previously in the literature for mixer manipulation, with the aim of generating vibration-based feedback to enrich the listener’s musical experience. Experimental results showed that the proposed method significantly increased the listener’s evaluation of sound consisting of high-frequency components, while a relatively poor evaluation was observed for sound containing low-frequency components.

P‐43: Effects of Changing Image Size on Depth Perception Using a Floating 3‐D Display

A floating-image display produces 3-D effects using a lens system that makes an image appear to float in the air. The authors examine the effects on depth perception and asthenopia of viewing a floating image that continuously changes in size. The results of the experiments suggest that viewers perceive the floating image to be moving back and forth as the image size changes despite the fact that the images actual position does not change. Monocular depth cues, especially changes in size, enhanced the 3-D effects of images presented on the floating-image display.
