The Wearable concept has been continuously developed to produce the wearable platforms which we use today in our fieldtrials and tests. An enormous amount of work has needed to be carried out in a continous evaluation.

- V1
- V2
- V2+ V3
- V3 unplugged
- V3 Complete Prototype
Spring 2000
V
- 0.1 Embedded PC Board attached to HDD and power Supply
- 0.2 Keyboard/VGA interfaced added, simple Test CRT BIOS uploaded
- 0.3 System powered up and able to boot DOS.
- 0.4 BIOS tweaks / Mouse added HDD preloaded with Flat Win95 Setup
- 0.5 Windows 98 Running stably after changes to BIOS and PSU
- 0.6 Network port installed on 10-Base-T (NB not PNP!)
- 0.7 Project box modified for Board and HDD, PSU external
- 0.8 Video-Input not operating, C&T driver needed re-configuration, GPIO Pins are back to front on the hardware!!!
- 0.9 Video-Input worked with a replacement board, Original 166MHz board been sent back for evaluation. Newer board is slight revision requiring a couple of software mods.
- 1.0 First WearCAM for Final Year Project Bench inspection, complete with automatic software for taking pictures.
- 1.1 Micro CMOS camera able to take pictures very small. Capture limited to 320x240 at 24 bpp for hardware reasons.
- 1.2 Battery made from 10x 7/5 AF cells mounted to army belt making wearable computer usable – Just!
- 1.3 Complete system made from new wearable, PSU and battery coupled with the Micro-Optical Head-Up-Display
- 1.4 Board substituted for original board which has had the SA71111 (Video input) replaced. Upgraded power to C&T69000 to reduce VGA ‘shimmering’
Summer 2000
- 1.5 BIOS changed to new phoenix BIOS, support for ACPI added. Reduction in power consumption of some 40%
- 2.0 New 266MHz board installed with similar configuration and V1.14 of the Phoenix BIOS, power consumption similar to 166MHz part but with added active cooling fan.
- 2.1 Battery life now in excess of 8 Hours, with further APM tweaks.
- 2.2 HDD spin down disabled due to ‘hanging’!
Autumn 2000
- 2.3 PSU – Prototype reduced to 20x18mm PCB design.
- 2.4 System now registered for use on the school network eee633 name given not WearCAM (sorry!).
Winter / Spring 2001
- 2.5 6.4” LCD panel support
- 2.6 Software re-write for field trials.
- 2.7 Battery now has plug in charger for use in the field.
- 2.8 Hot swappable Battery and charger dual configuration with new SMPSU.
- 2.9 Portrait mode supported for LCD
- 3.0.0 New input device finger mouse
- 3.0.1 Touch screen working for handheld display
Summer 2001
- 3.0.2 New machined funky case
- 3.0.3 166MHz V3 Prototype
Autumn 2001
- 3.0.4 700MHz PIII Prototype
- 3.0.5 Production of 2 further Wearables
