QR and Bar codes
We have a range of experience with 2d and 3d barcodes for stock control, lotteries and ticketing.
There are two main types of RFID tag – active and passive. The active types are normally for specialist applications and all of the projects we have done use the low frequency passive type that require no battery and are easy to incorporate into stickers, passes and tickets. For tracking people these tags require the use of readers at visitor flow areas such as doors or kiosks. In our experience a 3m wide arch is normally required for a reliable read of the tag. Production Science were the system integrator for a smart ticketing system at the British Music Experience that demonstrated ticket and web integration and brought together museum content, web content and visitor experience (for Land). more For tracking equipment or more complex tasks, without doubt the best RF tag system is the one made by Navigator Systems.
Most of our experience in robotics consists of programming with commercial robots. On a project with Pico Comau for Birmingham’s science museum ThinkTank we built a computer vision system for a car assembly robot that allowed it to watch the end of a drumstick and repeat a persons movements as drum beats on a real drum kit.
Computer vision techniques have been a part of interactivity since Myron Krueuger devised his Metaplay environment in 1970. Projects we have worked or consulted on using computer vision techniques are numerous but the one we enjoyed the most was Kids Room – a reproduction of a childs bedroom that came alive and provided a supporting narrative as children played in it to discover a hidden world. This project was devised by MIT and became a part of the Play Zone in the Millennium Dome.
