Project Details
- This demonstration presents a prototype solution of a natural (finger) pointing interface.
- "Based on an infrared signal power density weighting principle, a small infrared emitter on the user's finger and multiple receivers placed around the laptop screen generate data for a low-cost microprocessor system. The microprocessor sends its output to a laptop computer, where it is used to determine coordinates for the cursor location."
- "The prototype is not only a proof of concept, it is also a tool for further research on human performance in pointing and further development of interactive techniques."
