"Kinetic Touchless is a new interaction for touchless lift buttons that mirror your finger movements to recreate the tactile response of pushing a button. With contactless interactions on the rise in the face of COVID-19, most touchless tech tends towards a static sensor with a light or buzz to indicate an activated button, greatly diminishing the push button interaction."
It's a nifty effect for sure, but I wonder if the added cost/maintenance complexity might limit its appeal, particularly for building managers. Beyond that, I'd be very curious to see what end users would say about the system after using it for a long period of time: Is it reliable? Does it get annoying trying to gauge the distance required, or does your body "learn" it? Are accidental button presses common?
