273. LT-PAM: A new ranging method using dual frequency optical signals.

Author

Nakamura, Shigeki, Inoue, Yuki, Sugimoto, Masanori, and Hashizume, Hiromichi

Abstract

This paper describes a new ranging technique using optical signals. The proposed technique is called LT-PAM (Long-Term Phase Accordance Method), and it has been extended from our own ranging technique called Phase Accordance Method (PAM). LT-PAM transmits multiple sync patterns composed of two sinusoidal waves with different frequencies. Unlike chirp modulation techniques, LT-PAM transmits the two waves simultaneously and thus enables the shortening of measurement time. We have conducted experiments using two types of light sources, collimated and diffused light. The experimental results indicated that the proposed method showed a moderate level of accuracy by adjusting the measurement time. For example, LT-PAM using a light emitting diode transmitting multiple sync patterns lasting 4 ms achieved 19.5 mm standard deviation in a measurement ranging 1500 mm. We also describe the theoretical analyses related to the proposed technique and discuss possible improvements by comparing theoretical and experimental results. [ABSTRACT FROM PUBLISHER]

274. A puppet interface for the development of an intuitive computer animation system.

Author

Hiroki, Narukawa, Pantuwong, Natapon, and Sugimoto, Masanori

Abstract

In this paper, we introduce a puppet interface for the development of an intuitive animation system. Our puppet interface does not require any special devices and any type of puppet can be used. The puppet interface is developed by attaching ten visible markers onto a puppet. The user can manipulate the pose of the puppet interface to produce the desired motion in front of a camera. The puppet's joint angle information is captured by the camera and used to retrieve a suitable motion from a motion database. The retrieved motion data is transferred to a 3D character model to generate an animation. To avoid the occlusion problem, we propose an algorithm that estimates the joint angle by determining the position and rotation of markers adjacent to the occluded marker. Experiments confirmed that our proposed algorithm can generate correct results, although some occluded markers remained. [ABSTRACT FROM PUBLISHER]

285. CityVoyager: An Outdoor Recommendation System Based on User Location History.

Author

Jianhua Ma, Hai Jin, Yang, Laurence T., Tsai, Jeffrey J.-P., Takeuchi, Yuichiro, and Sugimoto, Masanori

Abstract

Recommendation systems, which automatically understand user preferences and make recommendations, are now widely used in online shopping. However, so far there have been few attempts of applying them to real-world shopping. In this paper, we propose a novel real-world recommendation system, which makes recommendations of shops based on users' past location data history. The system uses a newly devised place learning algorithm, which can efficiently find users' frequented places, complete with their proper names (e.g. "The Ueno Royal Museum"). Users' frequented shops are used as input to the item-based collaborative filtering algorithm to make recommendations. In addition, we provide a method for further narrowing down shops based on prediction of user movement and geographical conditions of the city. We have evaluated our system at a popular shopping district inside Tokyo, and the results demonstrate the effectiveness of our overall approach. [ABSTRACT FROM AUTHOR]

290. Hotaru: Intuitive Manipulation Techniques for Projected Displays of Mobile Devices.

Author

Costabile, Maria Francesca, Paternò, Fabio, Sugimoto, Masanori, Miyahara, Kosuke, Inoue, Hiroshi, and Tsunesada, Yuji

Abstract

Mobile devices (cellular phone, PDA, etc.) have so far been personal tools. Due to their evolution to multi-functionality, however, the devices have begun to be used by multiple people in co-located situations. This paper discusses near future technologies: a mobile device with a projector and intuitive manipulation techniques by using a video camera mounted on the device. In today's technologies, it is difficult to realize a mobile device with a small and lightweight projector that still retains the feature of mobility. Therefore, we have developed a system to project displays of mobile devices on a table, a floor, or a wall, by tracking their three-dimensional positions and orientations and using an existing LCD projector. The proposed system called Hotaru (a firefly, in English) allows users to annotate/rotate a picture or a document in a mobile device by touching its projected display with their fingers. Users can intuitively transfer a file between multiple devices by making their projected displays overlapped. Informal evaluations of Hotaru indicated that the proposed manipulation techniques could effectively support multiple people in co-located situations in conducting their tasks.

Abstract

We propose a novel technique for 3D tracking that integrates a single camera and ultrasound. We use ultrasound with the Extended Phase Accordance Method to measure the distance accurately to a moving target and the camera for identifying the 2D position of the target on the image plane. A prototype system consists of a target unit mounting one ultrasound transmitter and three infrared LEDs surrounding it, and a receiver unit with one inexpensive camera and one ultrasound receiver. We implemented these units in a lightweight and compact way (receiver unit size: 55 mm × 44 mm) to make the system robust to non-line-of-sight problems that frequently occur in trilateration or multicamera-based systems. To improve the ranging performance, we applied phase characteristic compensation of the ultrasound transducers by interpolating with a B-spline function and creating a compensated curved surface. Experimental results show that root-mean-square errors of the proposed system are 1.20 mm and 1.66 mm for static and mobile (target velocity: 1.0 m/s) settings, respectively. Thus, the performance of the system is comparable with that of high-end systems. Limitations of the proposed system and its possible applications are also discussed. [ABSTRACT FROM AUTHOR]
