title A real-time localization system for compactors
source Automation in Construction 10 (4) (2001) pp. 417-428
summary An operator-aiding system for compactors must incorporate a localization system. In this paper, we consider real-time kinematic (RTK) GPS and we present the solutions we have developed to maintain the positioning error lower than 0.2 m even during the satellite (limited) masking phases. By combining gyro, steering angle and speed measurements, we show that it is possible to obtain satisfying performances in dead-reckoning navigation with a low-cost internal sensor set. A forward–backward Kalman filter is proposed to deal with particularly long maskings, which typically occur when the machine works under bridges. Results of experiments carried out with an instrumented machine are presented to validate the proposed solutions.

title VR System by the Combination of HMD and Gyro Sensor for Streetscape Evaluation
source CAADRIA 2005 [Proceedings of the 10th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] New Delhi (India) 28-30 April 2005, vol. 2, pp. 123-128
summary In this paper, Virtual Reality System for Streetscape and Street space evaluation using the Virtual Reality system are concerned. Light and small VR system using the combination of HMD and 3 axes gyro sensor, which provides view stereoscopic environments and enable us to view all direction of streetscape, is presented. Next, the adaptability of this system for the streetscape and space evaluation is confirmed through two experiments. The sense of Height, Volume, Amenity, Depth, and Activeness of different stand points and those by different streets which have different width are investigated and several features of sense of Street space are clarified by the VR system.
