Control of Electro-Optical Displays

The complexity of modern electronic devices leads to increasing requirements concerning the human-machine interface (HMI). The array of the buttons, the selection of the display icons, and the design and lighting of the display become increasingly important. SAC, a system house of industrial machine vision, has attended to that subject: with the additional module HTM (human test module) the optical inspection of the HMI becomes standard.

Symbols, printed or lasered, can be inspected in terms of completeness, consistency of shape, and position (x, y, and angle). The brightness of the icons in day/night design can be determined, too.

Displays (LCD, LED, 7-/14-Segment, dot matrix, special symbols, etc.) can be checked for their functionality with simple macro commands. Segment failures, short circuits, and completeness can be checked as well as homogeneity, colour fidelity, and brightness of lighting.
The HT module is fully integrated into the graphical standard interpreter Coake. Application programmes can thereby be created graphically by the user easily via drag & drop.
