Seko, Keiichi and Fukuchi, Kentaro (2012): A guidance technique for motion tracking with a handheld camera using auditory feedback. In: Adjunct Proceedings of the 2012 ACM Symposium on User Interface Software and Technology 2012. pp. 95-96.

We introduce a novel guidance technique based on auditory feedback for a handheld video camera. Tracking a moving object with a handheld camera is a difficult task, especially when the camera operator follows the target, because it is difficult to see through the viewfinder at the same time as following the target. The proposed technique provides auditory feedback via a headphone, which assists the operator to keep the target in sight. Two feedback sounds are introduced: three-dimensional (3D) audio and amplitude modulation (AM)-based sonification.

Fukuchi, Kentaro, Sato, Toshiki, Mamiya, Haruko and Koike, Hideki (2010): Pac-pac: pinching gesture recognition for tabletop entertainment system. In: Proceedings of the 2010 International Conference on Advanced Visual Interfaces 2010. pp. 267-273.

We present our new interaction technique for tabletop system and video game application using it. This technique is for recognizing a pinching gesture performed with the thumb and forefinger and tapping gestures with them by a ceiling camera above the table. The positions and orientations of multiple gestures are recognized at 200Hz, and the users around the table are tracked by their arm positions. This technique is useful for large-sized tabletop system for multiple users because it does not require any additional equipments to them nor registration process before using the system. Some pilot studies demonstrated the robustness and accuracy of the proposed technique with displaying appropriate guide on the display. We also developed a video game application called "Pac-pac". A player can shoot a bullet along the orientation of his hand by tapping, from any side of the table. We exhibited Pac-pac several time and well-received.

Koike, Hideki, Nishikawa, Wataru and Fukuchi, Kentaro (2009): Transparent 2-D markers on an LCD tabletop system. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 163-172.

Tabletop systems are currently being focused on and many applications using these systems are being developed. In such tabletop systems, how to recognize real objects on the table is an essential and important issue. In existing tabletop systems, 2-D markers have been often used. However, their black-and-white pattern, which means nothing to humans, spoils the appearance of the object. We developed transparent markers on a liquid crystal display (LCD) tabletop system by using the polarization features of the LCD and optical lms. In particular, through experiments with various kinds of optical films, we found that two halfwave plates make the markers rotation invariant. By using the transparent markers, tangible transparent Magic Lenses(TM) applications were developed.

Sato, Toshiki, Mamiya, Haruko, Fukuchi, Kentaro and Koike, Hideki (2009): PAC-PAC: pinching gesture recognition for augmented tabletop video game. In: Proceedings of the 2009 ACM International Conference on Interactive Tabletops and Surfaces 2009. p. D8.

A novel tabletop entertainment system that allows simultaneous interactions by multiple participants was developed. The newly developed interaction technique of this system recognizes a pinching gesture performed with the thumb and forefinger. This gesture recognition technique enables rapid response and high degree-of-freedom input for the players.

Sato, Toshiki, Mamiya, Haruko, Koike, Hideki and Fukuchi, Kentaro (2009): PhotoelasticTouch: transparent rubbery tangible interface using an LCD and photoelasticity. In: Proceedings of the ACM Symposium on User Interface Software and Technology 2009. pp. 43-50.

PhotoelasticTouch is a novel tabletop system designed to intuitively facilitate touch-based interaction via real objects made from transparent elastic material. The system utilizes vision-based recognition techniques and the photoelastic properties of the transparent rubber to recognize deformed regions of the elastic material. Our system works with elastic materials over a wide variety of shapes and does not require any explicit visual markers. Compared to traditional interactive surfaces, our 2.5 dimensional interface system enables direct touch interaction and soft tactile feedback. In this paper we present our force sensing technique using photoelasticity and describe the implementation of our prototype system. We also present three practical applications of PhotoelasticTouch, a force-sensitive touch panel, a tangible face application, and a paint application.

Siio, Itiro, Masui, Toshiyuki and Fukuchi, Kentaro (1999): Real-World Interaction using the FieldMouse. In: Zanden, Brad Vander and Marks, Joe (eds.) Proceedings of the 12th annual ACM symposium on User interface software and technology November 07 - 10, 1999, Asheville, North Carolina, United States. pp. 113-119.

We introduce an inexpensive position input device called the FieldMouse, with which a computer can tell the position of the device on paper or any flat surface without using special input tablets or position detection devices. A FieldMouse is a combination of an ID recognizer like a barcode reader and a mouse which detects relative movement of the device. Using a FieldMouse, a user first detects an ID on paper by using the barcode reader, and then drags it from the ID using the mouse. If the location of the ID is known, the location of the dragged FieldMouse can also be calculated by adding the amount of movement from the ID to the position of the FieldMouse. Using a FieldMouse in this way, any flat surface can work as a pointing device that supports absolute position input, just by putting an ID tag somewhere on the surface. A FieldMouse can also be used for enabling a graphical user interface (GUI) on paper or on any flat surface by analyzing the direction and the amount of mouse movement after detecting an ID. In this paper, we introduce how a FieldMouse can be used in various situations to enable computing in real-world environments.
