"Active Click" is a new interface mechanism for addling tactile feedback to touch panels. A small actuator is attached to a body of PDA or the backside of a touch panel. The tactile feedback, created by driving the actuator with a short pulse, is perceived by the grasping hand or tapping finger-tip when the panel is tapped. Active Click is effective in(More)
We propose unvoiced speech recognition, "Mime Speech Recognition". It recognizes speech by observing the muscles associated with speech. It is not based on voice signals but electromyography (EMG). It will realize unvoiced communication, which is a new communication style. Because voice signals are not used, it can be applied in noisy environments; it also(More)
This paper proposes the application of a tree-structured clustering method that integrates the effects of noise as well as SNR variation in the framework of piecewise-linear transformation (PLT)-based noise adaptation for robust speech recognition. According to the clustering results, a noisy speech HMM is made for each node of the tree structure. An HMM(More)
We propose a method for recognizing the ID tags on gobjectsh in the real world that uses image information from a cell phone camera. The method offers robustness with regard to view−direction and view−distance. Instead of using projective transformation for geometric calibration and multi−view data, we use five color−rectangles based on the ggeometric(More)
The cellular phone offers significant benefits but causes several social problems. One such problem is phone use in places where people should not speak, such as trains and libraries. A communication style that would not require voiced speech has the potential to solve this problem. Speech recognition based on electromyography (EMG), which we call "Mime(More)
The recognition of telop characters in video has two problems: edge degradation and background noise. To overcome these problems, this paper proposes; (1) a feature that describes the shape of background region in addition to character region, (2) a classifier that dynamically decreases the influence of noise using the difference in number of pixel within a(More)
NTT DoCoMo Multimedia Laboratories are researching user interfaces that will enable you to use devices, objects, and information naturally and with ease as if they were part of your body. This article describes associated technical issues and introduces the concept of Human Centered Communication and Computing (HC3) based on the technologies described.(More)
