Poupyrev, Ivan, Oba, Haruo, Ikeda, Takuo and Iwabuchi, Eriko (2008): Designing embodied interfaces for casual sound recording devices. In: Proceedings of ACM CHI 2008 Conference on Human Factors in Computing Systems April 5-10, 2008. pp. 2129-2134.

“In the Special Moment project we prototype and evaluate the design of interfaces for casual sound recording devices. These devices are envisioned to be used by a casual user to capture and store their everyday experiences in the form of "sound albums" -- collections of recordings related to a certain situation. We formulate a number of design principles for such recording devices, as well as implement and evaluate two working prototypes. A candle recorder allows for capturing the general atmosphere at a party, and the children's book recorder records the interactions between parents and children while reading a book together.”

Rekimoto, Jun, Ishizawa, Takaaki, Schwesig, Carsten and Oba, Haruo (2003): PreSense: interaction techniques for finger sensing input devices. In: Proceedings of the 16th annural ACM Symposium on User Interface Software and Technology November, 2-5, 2003, Vancouver, Canada. pp. 203-212.

“Although graphical user interfaces started as imitations of the physical world, many interaction techniques have since been invented that are not available in the real world. This paper focuses on one of these "previewing", and how a sensory enhanced input device called "PreSense Keypad" can provide a preview for users before they actually execute the commands. Preview important in the real world because it is often not possible to undo an action. This previewable feature helps users to see what will occur next. It is also helpful when the command assignment of the keypad dynamically changes, such as for universal commanders. We present several interaction techniques based on this input device, including menu and map browsing systems and a text input system. We also discuss finger gesture recognition for the PreSense Keypad.”

Rekimoto, Jun, Ullmer, Brygg and Oba, Haruo (2001): DataTiles: A Modular Platform for Mixed Physical and Graphical Interactions. In: Beaudouin-Lafon, Michel and Jacob, Robert J. K. (eds.) Proceedings of the ACM CHI 2001 Human Factors in Computing Systems Conference March 31 - April 5, 2001, Seattle, Washington, USA. pp. 269-276.

“The DataTiles system integrates the benefits of two major interaction paradigms: graphical and physical user interfaces. Tagged transparent tiles are used as modular construction units. These tiles are augmented by dynamic graphical information when they are placed on a sensor-enhanced flat panel display. They can be used independently or can be combined into more complex configurations, similar to the way language can express complex concepts through a sequence of simple words. In this paper, we discuss our design principles for mixing physical and graphical interface techniques, and describe the system architecture and example applications of the DataTiles system.”
