Tangible acoustic interface (TAI), the key concept of which is to convert any touchable objects into natural interactive surfaces, is an innovative and exciting idea in human-computer interaction. A key challenge for its development is to accurately locate the tactile interactions. In this reported work, the Cramér-Rao lower bound is utilised to study the theoretical limits of impact localisation using the hyperbolic positioning approach in TAI applications. © 2009 The Institution of Engineering and Technology.
