Title:
- ReQTable: Square tabletop display that provides dual-sided mid-air images to each of four users
Presenter(s):
Description:
We propose “ReQTable”, an optical system displaying dual-sided mid-air images to each of four users with less stray light. Dual Slit Mirror Arrays (dual SMAs) can produce a mid-air image that multiple people can view simultaneously without wearing special equipment. Dual SMAs are rectangular and can theoretically display mid-air images in the four surrounding directions. However, they also produce unwanted light, called stray light, which is especially noticeable when mid-air images are displayed in some directions. It is difficult for users to identify stray lights, and they cannot concentrate on viewing only the mid-air images. To improve a user experience, it is necessary to suppress stray light. ReQTable displays mid-air images in four directions with stray light reduction.
