Hands-free, user-supported portable computer
The people in patent drawings always look so fulfilled, don’t they? This fellow is using a wearable computer with a head-mounted display and a microphone for voice input. At first I thought that the bricklike object on the ground was the computer. But it’s really an electrical device that the guy is testing (this computer was meant to aid the servicing of military equipment and similar items). He’s wearing the computer on a strap which can only be described as purselike.
