Takashima, Kazuki, Fujita, Kazuyuki, Itoh, Yuichi and Kitamura, Yoshifumi (2012): Elastic scroll for multi-focus interactions. In: Adjunct Proceedings of the 2012 ACM Symposium on User Interface Software and Technology 2012. pp. 19-20. Available online

This paper proposes a novel and efficient multi-focus scroll interface that consists of a two-step operation using a con-tents distortion technique. The displayed content can be handled just like an elastic material that can be shrunk and stretched by a user's fingers. In the first operation, the user's dragging temporarily shows the results of the viewport transition of the scroll by elastically distorting the content. This operation allows the user to see both the newly obtained and the original focus on the viewport. Then, three types of simple gestures can be used to perform the second operation such as scrolling, restoring and zooming out to get the demanded focus (or foci).

In: Proceedings of the 2011 ACM International Conference on Interactive Tabletops and Surfaces 2011. pp. 35-44. Available online

We propose a furry and scalable multi-touch display called the "FuSA2 Touch Display." The furry type of tactile sensation of this surface affords various interactions such as stroking or clawing. The system utilizes plastic fiber optic bundles to realize a furry-type texture. The system can show visual feedback by projection and detects multi-touch input using a diffused illumination technique. We employed the optical feature of plastic fiber optics to integrate the input and output systems into such a simple configuration that the display becomes scalable. We implemented a 24-inch display, evaluated the visual feedback and touch detection features, and found that our implemented display encourages users to interact with it in various actions.

Fujita, Kazuyuki, Itoh, Yuichi, Takashima, Kazuki, Kitamura, Yoshifumi, Tsukitani, Takayuki and Kishino, Fumio (2010): Anchored navigation: coupling panning operation with zooming and tilting based on the anchor point on a map. In: Proceedings of the 2010 Conference on Graphics Interface 2010. pp. 233-240. Available online

We propose two novel map navigation techniques, called Anchored Zoom (AZ) and Anchored Zoom and Tilt (AZT). In these techniques, the zooming and tilting of a virtual camera are automatically coupled with users' panning displacements so that the anchor point determined by users always remains in a viewport. This allows users to manipulate a viewport without mode-switching among pan, zoom, and tilt while maintaining a sense of distance and direction from the anchor point. We conducted an experiment to evaluate AZ and AZT and compare them with Pan&Zoom (PZ) [17] and Speed-dependent Automatic Zooming (SDAZ) [10] in off-screen target acquisition tasks and spatial recognition tests. Results showed that our proposed techniques were more effective than those of competitors in reducing time to reach off-screen objects while maintaining users' sense of distance and direction as well as PZ.

In: Proceedings of the ACM Symposium on User Interface Software and Technology October 7-10, 2007, Newport, Rhode Island, USA. pp. 279-288. Available online

Multi-display environments compose displays that can be at different locations from and different angles to the user; as a result, it can become very difficult to manage windows, read text, and manipulate objects. We investigate the idea of perspective as a way to solve these problems in multi-display environments. We first identify basic display and control factors that are affected by perspective, such as visibility, fracture, and sharing. We then present the design and implementation of E-conic, a multi-display multi-user environment that uses location data about displays and users to dynamically correct perspective. We carried out a controlled experiment to test the benefits of perspective correction in basic interaction tasks like targeting, steering, aligning, pattern-matching and reading. Our results show that perspective correction significantly and substantially improves user performance in all these tasks.
