Inflatable Mouse is a volume-adjustable user interface. It can be inflated up to the volume of a familiar mouse, but be deflated and stored flat in a PC card slot of a laptop computer when not in use. Inflatable Mouse functions just like a typical mouse; moreover, it provides new interaction techniques by sensing the air pressure in the balloon of the(More)
Most of the commercialized wearable text input devices are wrist-worn keyboards that have adopted the minimization method of reducing keys. Generally, a drastic key reduction in order to achieve sufficient wearability increases KSPC (Keystrokes per Character), decreases text entry performance, and requires additional effort to learn a new typing method. We(More)
Frottage and rubbing are drawing techniques that allow interesting visual expression through simple rubbing actions revealing a texture or a pattern hidden in the background. Specifically, frottage is a drawing technique where one puts a textured surface, such as wooden planks, metal sheets, wire nets, and hemp cloth, under a sheet of paper and rubs over it(More)
In this paper, we introduce digital rubbing, which is a playful and intuitive interaction technique for transferring a graphic image directly onto paper. We designed TransPen and MimeoPad to realize digital rubbing. With these drawing tools, children and adults can use rubbing motions to transfer a digital image directly to paper and produce a drawing with(More)
This paper presents the Button Keyboard, a very small wearable keyboard with universal usability. The Button Keyboard has high wearability and social acceptance due to its remarkably small size. As it is roughly button sized (33㎜×33㎜), it can be worn on the body without any discomfort. In addition, it adapts a mobile QWERTY layout to improve text entry for(More)
New millimeter wave interferometric, multifunctional sensors have been studied for industrial sensing applications: displacement measurement, liquid-level gauging and velocimetry. Two types of configuration were investigated to implement the sensor: homodyne and double-channel homodyne. Both sensors were integrated on planar structure using MMIC (Microwave(More)
