Application:

Compact Computer Aid for Maintenance (CCAM).

Purpose:

Computational aid for power plant maintenance.

Users:

Mechanics and electricians.

Environment:

Hand held PC-compatible with one-quarter VGA text display.

Comments:

The CCAM application shown below is used to align pumps and motors. The challenge posed by this interface is the simulation of graphics using a small text based display and operational consistency across multiple pieces of plant equipment. On-screen prompts are coordinated with the color coded custom keyboard to provide context-sensitive assistance.
