<i>Ambient lifestyle feedback systems</i> are embedded computer systems designed to motivate changes in a person's lifestyle by reflecting an interpretation of targeted behavior back to the person. Other interactive systems including "serious games" have been applied for the same purpose in areas such as nutrition, health and energy conservation, but they(More)
In the future, micro processors will be embedded in various appliances such as home appliances, digital AV appliances, and personal appliances. These appliances will be connected to various types of networks, such as Internet, and communicate with each other. The communication of appliances would integrate some services provided by these appliances and make(More)
In this paper, we propose a novel computer gaming style Lifestyle Ubiquitous Gaming, where our experience is enriched in our daily lives by using gaming concepts. In lifestyle ubiquitous gaming, human daily activities are implicitly tracked and interpreted. Then, the feedback of the activities are returned to a user as a game system' presentation. The user(More)
Our daily lives will be dramatically changed by embedded small computers in our environments. The environments are called <i>ubiquitous computing environments.</i> To realize the environments, it is important to reduce the cost to develop ubiquitous computing applications by encapsulating complex issues in middleware infrastructures that are shared by(More)
Using a single personal device as an universal controller for diverse services is a promising approach to solving the problem of too many controllers in ubiquitous multimodal environments. However, the current approaches to universal controllers cannot provide intuitive control because they are restricted to traditional mobile user interfaces such as small(More)
Various home appliances and personal appliances are expected to be connected to the Internet in the near future, and the number of such appliances will become extremely large. The Internet will provide connectivity between nodes running various services and applications, in order to provide new advanced functionality. However, the conventional IP protocol(More)
In the future, many of the physical objects that surround us will be augmented with microprocessors and wireless transceivers. They will communicate with each other, quietly monitor our daily activities and notify us of important events. Any piece of relevant information on the Internet will be available to us anytime and anywhere. We call this scenario the(More)
We report the development of a multiplex stimulated Raman microscope for spectral imaging through multi-channel lock-in detection with a single light source. A white pump beam is prepared with a piece of photonic crystal fiber (PCF). The system does not require the synchronization of plural light sources or the scanning of their wavelengths, and thus a(More)
We present <i>CookieFlavors</i>, a TUI prototyping tool that provides a set of physical input primitives realized by coin-size Bluetooth wireless sensors named <i>Cookie</i>. Developers can attach CookieFlavors on any physical objects and examine the suitability of tangible input in a TUI prototype phase. We have built a map viewer application and projected(More)
