A white paper by Richard Berglind, Sr Optical Engineer at Neonode
There is a need for long-term solutions to minimize the transfer of pathogens in public areas. When it comes to the public touchscreens found in self-service kiosks and checkout counters, or button interfaces in elevators and ATM machines, many would prefer to avoid touching the screens and buttons due to the risk of spreading pathogens residing on these surfaces.
Neonode® technology provides precise and accurate means to interact with a device, while eliminating the need for physical contact.
White Paper Introduction
Neonode Touch Sensor Modules are perfectly suited for contactless touch solutions. They provide precise and accurate means to interact with a device, while eliminating the need for physical contact.
The sensor module projects a sheet of light that is responsive to touch thanks to its ability to detect reflections from objects intersecting the projected light. The easiest and most cost effective way to implement a contactless touch solution is to raise the projected sheet of light above the display by controlling the spacing between the sensor module and the display, resulting in a touch interaction area hovering above the display. An additional sensor module could be stacked on top of the first, to add flexibility to the design of the user interface.
Implementation of contactless touch with a single touch sensor module raised above the display creating a distance between the screen and the interaction area.
There are situations where an elevated touch solution is less than optimal. A user interface with small icons may suffer from inevitable parallax effects. Explicit visual feedback on the screen, which is often a necessity, is problematic from a privacy point of view. Under these conditions, interaction with a projected in-air image provides an excellent alternative.
