Pointing is a fundamental enabling operation for human-computer interaction across a broad spectrum of scenarios. The paper presents a study exploring how to develop a pointing system for truly wearable, rather than hand-held, computing. It describes a Fitts' law study of pointing based on motions in free-space captured using an inertial sensor pack. It… (More)
A daily-wear wearable system is one of the most convenient mediums in practical application scenario of transferring various information data or services between two users as well as between a user and a device. To implement this service scenario, we chose to develop a wearable forearm mounted accelerometer based input system. A set of gesture commands was… (More)
We describe a new input method that utilizes patterned vibration that is generated through the finger writing on a textured pad. Using a flexible or a foldable textured pad which can be worn by the user can bring more diverse applications than conventional input interfaces such as a touchpad or tablet screen.
The ever decreasing size of information devices these days does not allow even the space for small input devices such as a touchpad or a 3x4 keypad. We introduce here an input device, FeelTip, as a solution for very small information devices. The main idea is to exchange the usual roles of a finger and a surface in a touchpad; a device has a tip and a… (More)
Multi-touch interfaces are becoming popular as a new input means for the various applications. In this paper, we suggest a new Korean text entry method using a multi-touch interface called MPT (Multi-Point Touch) input method. We conducted a text entry performance test comprising 4 sessions for 10 participants, and compared the result with an existing… (More)
Wearable computer can be worn anytime with the support of unrestricted communications and variety of services which provides maximum capability of information use. Key challenges in developing such wearable computers are level of comfort that users do not feel what they wear, easy and intuitive user interface and power management technique. This paper… (More)
