Abstract

This paper presents a card type battery-less information terminal $CardBIT - and a method of situated interaction that uses single-lens cameras. The CardBIT system provides situated information support at locations such as exhibition halls, train stations and streets. CardBIT can operate without a battery because it utilizes energy from the information car-tier and the user. It realizes location-and-direction-based interaction; a user can get appropriate information for his/her position and direction. The most significant feature of the CardBIT is its high portability because it is easily implanted into widely-used IC cards. Based on information accumulated in the CardBIT, personalized information in the form of sound, such as speech or music, is provided. Furthermore, a user can signal to the interface system and obtain information dynamically. This paper introduces the CardBIT system concept and its implementation using cameras, position estimation, and sign recognition methods. Our experiments show the feasibility of the proposed system.

一种卡式无电池信息终端系统:用于定位交互的CardBIT

本文介绍了一种卡式无电池信息终端$CardBIT -和一种使用单镜头相机的定位交互方法。CardBIT系统在展览厅、火车站和街道等地点提供定位信息支持。CardBIT可以在没有电池的情况下工作，因为它利用来自信息层和用户的能量。它实现了基于位置和方向的交互;用户可以获得适合自己位置和方向的信息。CardBIT最显著的特点是它的高便携性，因为它很容易植入广泛使用的IC卡。根据CardBIT中积累的信息，以语音或音乐等声音形式提供个性化信息。此外，用户可以向接口系统发送信号并动态获取信息。本文介绍了CardBIT系统的概念及其在摄像机、位置估计和符号识别等方面的实现方法。实验证明了该系统的可行性。
