Knowledge is commonly socially constructed, through collaborative efforts towards shared objectives or by dialogues and challenges brought about by different persons' perspectives.

Manabe, Hiroyuki and Fukumoto, Masaaki (2012): Touch sensing by partial shadowing of PV module. In: Adjunct Proceedings of the 2012 ACM Symposium on User Interface Software and Technology 2012. pp. 7-8.
A novel touch sensing technique is proposed. By utilizing partial shadowing of a photovoltaic (PV) module, touch events are accurately detected. Since the PV module also works as a power source, a battery-less touch sensing device is easily realized. We develop a wireless touch commander consisting of 6 PV modules so the user can input by using both touch and swipe actions.

Manabe, Hiroyuki and Fukumoto, Masaaki (2011): Tap control for headphones without sensors. In: Proceedings of the 2011 ACM Symposium on User Interface Software and Technology 2011. pp. 309-314.
A tap control technique for headphones is proposed. A simple circuit is used to detect tapping of the headphone shell by using the speaker unit in the headphone as a tap sensor. No additional devices are required in the headphone shell and cable, so the user can use their favorite headphones as a controller while listening music. A prototype is implemented with several calibration processes to compensate the differences in headphones and users' tapping actions. Tests confirm that the user can control a music player by tapping regular headphones.

Manabe, Hiroyuki and Fukumoto, Masaaki (2009): P-recognition: you are already recognized. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 3901-3906.
The user's intention is reflected in not only the actual input action but the ones immediately before it as well. "P-Recognition"" recognizes the preceding actions, and predicts the intention just when the actual action starts. This paper tests P-Recognition in a pen-based map navigation interface as an example, where the map is panned by user's dragging strokes and zoomed by user's enclosure by a circle. The feasibility of the proposal is confirmed in an experiment. We find that dragging and circling actions are distinguishable before the pen touches the screen. Moreover, for some users we can recognize their intention to write text. It is confirmed that the user's intention is present in the preceding actions and so is detectable.

Fukumoto, Masaaki (2009): PuyoSheet and PuyoDots: simple techniques for adding "button-push" feeling to touch panels. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 3925-3930.
Two simple techniques for touch-panel based portable information devices are proposed. A soft-gel based transparent film named "PuyoSheet" placed over a touch panel provides button-push feeling to the fingertips. Another configuration, soft-gel based small dots, named "PuyoDots", is attached to the backside of a handheld device provides button-edge and button-push feelings to the fingertip(s) that hold the device. Preliminary evaluations indicate that proposed techniques improve "usability" and "preference" without deteriorating input speed or error rate compared with an ordinary touch panel device.

"Whisper" is a new wrist-worn handset, which is used by inserting the fingertip into the ear canal. A received signal is conveyed from a wrist-mounted actuator to the ear canal via the hand and a finger by bone conduction. The user's voice is captured by a microphone mounted on the inside of the wrist. All components of Whisper can be mounted on the wrist, and usability does not decrease if the size of components is miniaturized. So, both wearability and usability can be achieved together. The way Whisper is operated is similar to that of an ordinary telephone handset. Thus, onlookers may not look upon Whisper's operation as "talking to oneself", even if the associated PDA is controlled by voice commands. Whisper is especially effective in a noisy environment. Signals received via bone conduction can be heard clearly in the presence of noise without raising the volume (-12 dB at noise = 90 dB(A) in comparison to cellular phone handset). Whisper is also effective in avoiding the annoying problem of the user's voice being raised in a noisy situation. Feedback of the user's utterance is boosted by bone conduction when covering the ear canal with a fingertip, then the user's voice does not need to raised in the presence of noise (-6 dB at noise = 90 dB(A) in comparison to cellular phone handset). Whisper is useful as a voice interface for a wrist-worn PDA and cellular phone.
