I have always thought the finger and rings are ideal places for control devices. This new project seems very versatile and natural to use. Would work well with Google Glass.
The Raspberry Pi has already put affordably home computing environments into the hands of many and its success indicates the interest and demand, 1 million sold and counting. Lets hope the BBC's plans will stimulate and add to this."The lesson from the 1980s is that the availability of hardware and the use of television to stimulate demand for computer literacy was not in itself enough. The project relied on the creation of a large amount of training, informal learning and curricular material; the broadcasts were part of a complete instructional package further widened by the growth of home computing magazines. Informal, rather than formal, learning seems to have been particularly influential on those who subsequently founded companies."
“The effective exploitation of microprocessor technology in Britain will ultimately depend on the creativity and imagination that is brought to bear on the problems and possibilities of computer applications, and hence the capacity of the subject to attract the best minds and the liveliest talents. Our failures over the past years to compete in world markets for industrial goods have probably been at least partly due to the shortage of good scientists and engineers, through a failure to attract more young people to science based subjects.”
