Products that have to be operated by people require a user interface, also referred to as a human-machine-interface or HMI. HMIs exist in all sorts and sizes, but the most common HMIs for electronic products (apart from keyboards and monitors) are:
· Buttons (luminous or not) and/or a classic (7-segment) display;
· Buttons and a graphic display;
· A graphic display with touch control.
The design of a good HMI with graphic display requires a lot of insight into how the end user will use the product. The most prevalent steps for the development are the monitoring in practice, consultation with (potential) end users, and the development of mock-ups, which are more or less elaborate demonstrations that end users can evaluate. Experience in this area helps to produce a good result quickly.
HedoN has developed different user interfaces, sometimes in cooperation with a design firm. The technique used for this purpose by us varies. From electronics and embedded software, whether or not bare metal, to Linux-subsystems on which a web server operates and that can be approached from a browser on a PC. Or systems based on software developer environments like Qt.
A few examples of HedoN user interfaces can be viewed via the links underneath.
