Remember cycling in the dark on your way to school (or work)? Still dozing a bit in the dark...it is wintertime, it is cold and you are wearing gloves.
Semi-consciously you follow your path, perhaps even signalling with your hand. But you do not register the oncoming car, moped, other bicycles.
improve safety in such circumstances I would like to enhance [Lardybloke]'s idea of torch gloves into signalling gloves: as soon as you stretch your finger a minute switch detects the erect index finger and starts to illuminate an array of LED's on your finger and glove. The other traffic will detect a bright flashing signal. You continue to doze while other people react and move into safety...
For the more communicatevely challenged we can enhance the glove with a special middle vinger detection. As soon as the middlefinger is raised, all sorts of offensive patterns become visible on the glove.
And to imbed the product in the computer age: it has an infrared interface to your computer, so that you can download new patterns from the Internet.
