HMI

Definition
HMI is the acronym of Human Machine Interface.
That refers to set of devices allowing interaction between the computer and its user.

To remember
Acquisition interfaces: keyboard, mouse, joystick, motion sensor (WiiMote, Kinect...), and microphone.
Rendering Interface: screen, stereoscopic 3D glasses.
Combined interfaces: touch screen, force feedback control.

Extra
The glasses said 3D can be of several types:
• 3D glasses (active or passive) which allow to have a 3D rendering come from an external screen.
• Stereoscopic 3D glasses which integrate two screens (one per eye) in order to feign the third dimension.
We talk about stereoscopic and gyroscopic 3D glasses when these integrate a motion detector in order to modify the display according to the head position.

Current development version, no « standardized » (finalisation of the spec in 2014).
It allows the direct taken over of the Rich media (audio and video) and the interactive contents.
