Accessible Ultrasonic Positioning

A positioning system´s design must account for several aspects of usability, most of which are determined by the application the system supports. The development of inexpensive, easy-to-use positioning technology simplifies the deployment of location-based applications. To explore the ubiquitous positioning systems´ design space we use the term accessibility, which encompasses all aspects of usability. We´ve at tempted to address several of these aspects in the design of ultrasonic positioning systems. Our solutions score better in some categories than in others, but our approach has enabled us to design and install more than 20 systems for use in permanent and temporary applications
