A European embedded computing specialist has announced a wrist-worn wearable computer that runs embedded Linux. Eurotech's WWPC ("wrist-worn PC") offers a wealth of standard PC interfaces, along with several innovative wearable-specific features.

The WWPC weighs seven ounces (200 grams) without straps/batteries, Eurotech says.

The WWPC offers several wearable-specific innovations, according to the company, including a patented orientation sensor that can be configured to induce standby when the user's arm drops. Additionally, the device's tilt sensor can be used to detect motionless operator states, while a built-in GPS receiver and "dead reckoning" technology enable the device to serve as a location-transmitting beacon.

The WWPC is based on an unspecified low-power embedded processor. It boots from 32MB of flash, and has 64MB of SDRAM. Storage can be expanded through an SD-card slot supporting cards up to 1GB.

Standard PC interfaces include WiFi, Bluetooth, and fast infrared networking, USB host and device ports, sound, built-in speakers, and a headphone jack. The device has a "daylight-readable" 2.8 x 2.2-inch touchscreen LCD, and also supports human interface devices such as microphones and headsets connected via USB or Bluetooth, the company says.

Additional claimed features include:

• Direct-access keypad
• L1 16-channel GPS receiver with active helix antenna
• IrDa (up to 4Mbps)
• Bluetooth v1.1 (up to 721 Kbps)
• LAN 802.11b (up to 11Mbps) with "hardware coexistence handshake"
• Specific internal antennas
• Supports "different configurable audio/video user interfaces"
• Supports Linux or Windows CE

"The hex clock arranges time in a more consistent and logical manner than our present clock. Instead of dividing the day into arbitrary divisions (twenty-four hours in a day, sixty minutes in an hour, etc.), the hex clock represents time of day as a single hexadecimal number. A hex clock displaying three digits gives even better resolution than a standard clock, which displays a digit (or two) for the hour and two for the minutes."

"Swatch has divided the virtual and real day into 1000 "beats". One Swatch beat is the equivalent of 1 minute 26.4 seconds. That means that 12 noon in the old time system is the equivalent of @500 Swatch beats." Try the Internet Time Converter
