This mobile phone and information terminal being developed by NTT DoCoMo uses the human hand for input and output. The voice signal received from the phone is conveyed by bone conduction to the fingertip (like the 1980's bone fone). To listen, the user inserts the fingertip into the ear, which not only enables the incoming voice to be heard clearly even in noisy environments, but also enables the user to speak in a low voice (see schematic). In addition, calls can be started and ended by rhythmically touching the fingertips together in what is called an "OK Tapping" operation, so that the user doesn't have to find and push small buttons.

I was able to try out a prototype at ISWC. It really does work, but it requires that you place the fingertip carefully so that your finger bone touches the skull bones. It also required a bit of pressure to be applied constantly (to keep the bones tightly together), which made long conversations tiring. Also, the vibrating ring feels quite weird.
The sound quality is not the best either, but is nevertheless quite sufficient.
