This paper describes how to mount a new pointing device by which users, who have an existing metaphor for using information appliances, can effectively apply that including Personal Computer (PC) We propose the system wearing the operation lens support, which is called ”OPR-LENS (Operation-Lens)” The OPR-LENS system is composed of the OPR-LENS module and the OPR-LENS device, and mounted on the server and the viewer software connected via TCP/IP, respectively The OPR-LENS device forms a temple block suitable for a palm operation Users’ manipulation can be effectively supported by the effect of the spherical lens with the partial GUI image This research investigates the evaluation of the OPR-LENS system through mounting a prototype system and implementing the performance evaluation experiment In addition, the application example when applying to the existing metaphor such as information appliances was shown in this paper

OPR-LENS: Operation-Lens System for Supporting a Manipulation of Information Appliances

We propose a novel interface in mobile environment called “Ubi-Finger” that realizes sensuous operations for PDA and information appliances by gestures of fingers. Since gestures are usual methods of non-verbal communications and enables sensuous operations for users, many researches on them carried out especially in the field of Virtual Reality. However most of those existing gesture-input systems are either very expensive or large, and have not been used in mobile environment. In contrast, Ubi-Finger is a gesture-input device, which is simple, compact, and optimized for mobile use. We develop prototype systems, and evaluate how effective our approach works.

Ubi-Finger : Gesture Input Device for Mobile Use

A new concept of "Attachable Computer" is proposed for the purpose of augmenting the use of daily artifacts by fit-up type small computer devices which can be directly attached on user interfaces of the artifacts. Attachable Computer is a small computer device which can recognize situations on the user interface of electric household appliances such as a light switch or a display panel of video tape recorder by a small sensor and a simple image recognition technique. We have designed a prototype system which can control a computer system by manipulating the user interface of real world artifacts. The system consists of a portable micro computer and small sensors such as a photo-sensor or a CCD camera. By attaching the computer device directly to the user interface of artifacts, situations on the user interface of artifacts are captured by sensors, and recognized through a simple image recognition technique.
