A European research and development firm has announced a seven-ounce, wrist-worn wearable computer with a 2.2 x 2.8-inch color touchscreen.
Eurotech’s WWPC ("wrist-worn PC") offers a wealth of standard PC interfaces, along with several innovative wearable-specific features, the company claims. It targets emergency rescue, security, healthcare, maintenance, logistics, and "many other" applications.
According to Eurotech, the WWPC integrates everything users expect of a PC, in a versatile, ergonomic form factor that supports a variety of wrist sizes. It can be worn over or under work clothes, and has flexible left- or right-handed straps that enclose dual 2-cell Li-polymer rechargable batteries. Claimed battery life is six hours in "fully operational" mode, or eight hours under normal circumstances.
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
Additional claimed - 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
According to its website, Eurotech’s corporate strategy is to "define and penetrate new and emerging markets." The company also offers rugged surveillance systems for public transportation that run Linux.
