Demand rises for “no touch” hologram elevator buttons

A technology company in the city of Hefei, west of Shanghai, has attracted more than 100 orders for its holographic lift buttons as Chinese look for ways to avoid touching surfaces that may harbour the Covid-19 virus. The device works by projecting an image of buttons in the air, and allowing users to “touch” them. The maker, Easpeed, says it can be fitted to all elevators, and has a response time of less than 30 milliseconds. The system is relatively expensive, at about $2,000, prompting some building owners to opt for retrofitted voice controls, at a cost of around $500. This has been done in hospitals in Yichang, Hubei Province, and Beijing’s Xiaotangshan Hospital.
