Wearable computing is a new paradigm shift in computing. There has been several already. In the seventies not many had access to a computer, and those that had used a terminal maybe an early user had a Teletype ASR 33… I myself used an model 35, which was very robust.
One of the first personal computers was the Apple II, and soon came the PC. This was in itself a revolution. Compaq released a portable computer in the late eighties and then we had different kinds of laptops. Today we have incredible good laptops with good battery life, high resolution screens and good computational power.
Many have shifted into tablets and smart phones. They can do most of the job of a laptop – you can read you emails, follow Face-Book, and other activities on the Internet.
With the invention of devices like Google Glasses, Moverio, and Oculus Rift we see a new way of using computers (some CPU) and interaction over Internet. These devices will be further developed to allow augmented reality – what you see on the screen (in the glasses) are mixed with the real world. Your screen is private – a tablet or laptop is not as private. The screen can be much larger than any laptop, since it can sense your head movements and show other parts of your virtual display (of which you see part of in the glasses).
Given this opportunity you need an input device that is as powerful. You do want to type a letter or take notes. Speech recognition is an option if you are alone – not such a good idea if you are taking notes in a class, board meeting or writing a love letter on the bus.
The Project Virtual Keyboard will give you the keyboard that fits very well with this new way of doing computations. You will not look down to your phone any more, you will look around and at the same time have your glasses to show you Google maps while you are walking around in a new city. The Virtual Keyboard will be used to zoom in and out and switch between map mode and street mode.
