A number of non-contact self-service machines and non-contact elevator buttons have been put into use in many hospitals and office buildings in the city to help reduce the risk of cross-infection in public areas. These devices, taking advantage of a kind of interactive holographic air cast imaging technology, can project elevator buttons and operation interface of self-service machines into the air to enable users to complete operation without touching the real objects.
