In this paper, we propose a method of personal positioning for a wearable Augmented Reality (AR) system that allows a user to freely move around indoors and outdoors. The user is equipped with self-contained sensors, a wearable camera, an inertial head tracker and display. The method is based on sensor fusion of estimates for relative displacement caused by(More)
This paper describes an embedded pedestrian navigation system composed of a self-contained sensors, the Global Positioning System (GPS) and an active Radio Frequency Identification (RFID) tag system. We use self-contained sensors (accelerometers, gyrosensors and magne-tometers) to estimate relative displacement by analyzing human walking locomotion. The GPS(More)
We define Situated Music as a framework that selects and plays a tune according to a situation. The selected and played tune itself is also referred to as Situated Music. In this paper, we describe Interactive Jogging, that is an application of Situated Music for jogging. Measuring pitch acceleration with an accelerometer attached on a headphone, we(More)
This paper describes an algorithm to detect and track a hand in each image taken by a wearable camera. We primarily use color information, however, instead of predened skin-color models, we dynamically construct hand-and background-color models by using a Gaus-sian mixture m o del to approximate the color histogram. Not only to obtain the estimated m e an(More)
In this paper, we describe a n i m p r oved method o f personal positioning and orientation using image registration between input video f r ames and panoramic images captured b eforehand. In our previous work, we proposed the method of image registration with an ane transform. However, the ane transform is generally not capable of image registration(More)
We propose a wearable active camera with laser pointer (WACL) as a human interface device for use in telecommunications. The WACL laser pointer is attached to the active camera-head and it can point a laser spot while elevating and panning the camera-head. In our system, a remote instructor can observe around the worker, who is wearing the WACL,(More)
This paper presents a new Tangible TableTop (TTT) interface to support remote collaborative works between an expert and multiple field workers in direct and intuitive way. The TTT interface consists of a large touchscreen LCD as a tabletop display and small ultrasonic transmitters that can measure their 3D positions as physical tags on the display. The(More)
In this paper, we propose a method of personal positioning that combines images taken from a wearable camera with data from self-contained sensors attached to the user through a Kalman filter as a data integration mechanism. The proposed method estimates the user's position and direction by image registration between the input images from the camera and a(More)
This paper describes a fast and robust image registration method that can be used to create a panoramic image/video from video sequences. To estimate alignment parameters for image registration, the method computes pseudo motion vectors that are rough estimates of optical ows at each selected pixels. Using the proposed method, we implemented a software(More)
