Osaka Univ: Development of groundbreaking touch display: Guidance for the blind
Osaka Univ: RESOU Group
A special polymer sheet that detects temperature differences and changes its adhesive properties has been placed on the display screen.
This display system can “sense local temperature changes” and “control surface stickiness” (Figure 1).
Research achievement points:
Display by adding adhesiveness (1D) to image information (2D).
Extended touch and swipe operation functions.
Applicable for presenting information to the visually impaired.
Application: This display
Hierarchy of folders: Change the stickiness according to the size of the folder, you can know the capacity of the folder just by touching.
Swipe operation: Increase the adhesiveness of important parts, generate frictional force, and stop swiping fingers.
Guidance for the visually impaired: Application to touch displays is also possible.
Video content: Adding stickiness to video information gives the video a sense of realism.
