Ayatsuka, Yuji and Rekimoto, Jun (2005): tranSticks: physically manipulatable virtual connections. In: Proceedings of ACM CHI 2005 Conference on Human Factors in Computing Systems 2005. pp. 251-260.

A virtually connected medium called tranStick is described that functions both as a "virtual wire" and as a "memory card" containing a shared space. A user can connect two networked devices by simply placing one of a pair of tranSticks with the same identifier into each device. The tranSticks provide feedback indicating that the devices are connected; the connection to be closed or changed in the same way it would be if the devices were connected by a physical cable. A user can also access to a shared space on a network as if the space were in the tranStick. Since tranSticks contain long secret keys, the process of finding another tranStick with the same identifier can be encrypted. The tranStick approach differs from other approaches in that it provides feedback from the connection as well as serving as a medium for establishing a connection, and it enables disconnection and switchover to be done intuitively because the operations are reversible.

Ayatsuka, Yuji, Rekimoto, Jun and Matsuoka, Satoshi (1998): Popup Vernier: A Tool for Sub-Pixel-Pitch Dragging with Smooth Mode Transition. In: Mynatt, Elizabeth D. and Jacob, Robert J. K. (eds.) Proceedings of the 11th annual ACM symposium on User interface software and technology November 01 - 04, 1998, San Francisco, California, United States. pp. 39-48.

Dragging is one of the most useful and popular techniques in direct manipulation graphical user interfaces. However, dragging has inherent restrictions caused by pixel resolution of a display. Although in some situations the restriction could be negligible, certain kinds of applications, e.g., real world applications where the range of adjustable parameters vastly exceed the screen resolution, require sub-pixel-pitch dragging. We propose a sub-pixel-pitch dragging tool, popup vernier, plus a methodology to transfer smoothly into 'vernier mode' during dragging. A popup vernier consists of locally zoomed grids and vernier scales displayed around them. Verniers provide intuitive manipulation and feedback of fine grain dragging, in that pixel-pitch movements of the grids represent sub-pixel-pitch movements of a dragged object, and the vernier scales show the object's position at a sub-pixel accuracy. The effectiveness of our technique is verified with a proposed evaluation measure that captures the smoothness of transition from standard mode to vernier mode, based on the Fitts' law.

Ayatsuka, Yuji, Matsuoka, Satoshi and Rekimoto, Jun (1996): Penumbrae for 3D Interactions. In: Kurlander, David, Brown, Marc and Rao, Ramana (eds.) Proceedings of the 9th annual ACM symposium on User interface software and technology November 06 - 08, 1996, Seattle, Washington, United States. pp. 165-166.

We propose a new feedback technique for 3D interaction using penumbrae which the objects cast. Rather than generating a real penumbra, which is computationally expensive, a fast, simplified algorithm is employed, which also is better suited for position feedback purposes. User studies show that 1) compared to orthographic shadow projections, 3D spatial recognition and placement tasks are substantially faster with our penumbrae, and 2) the users feel the feedback to be more natural.
