Common portable LCD display FEATURES: High resolution colour video image. Image that appears in the person's line of sight. Viewing angle comparable to viewing a 26" monitor from 2, meters (6.5 Feet) away. Ultra light-weight, no major disturbance in the eyesight. Head mounted display FEATURES: A typical HMD has either one or two small displays with lenses and mirrors embedded in a helmet, eye-glasses or visor. The display units are miniaturized and may include CRT, LCDs, Liquid Crystal on Silicon (LCos), or OLED KEY BOARD At the higher end, you can get a "twiddler" from Hand key, or keyboard from info grip. You can connect micro switches that enable you to plug directly into the keyboard port. A combination keyboard that weighs 4 ounces and fits in the palm of your hand. The twiddler 2 is an existing technology of wearable computing. HARD DRIVE Many hard drives commonly used in laptop computers can withstand operational shock, it is common to go jogging while editing, and sometimes shoot momentary video while on horseback or riding a mountain bike down the centre of a line bumping over every railway tie, and capturing the experience on a hard drive. It is possible to carry enormous amount of hard drive space on your body. Prof Martin has 36GB hard
