Method and apparatus for providing personalised audio-visual instruction

Abstract

A method of and apparatus (10) for providing a personalized audio-visual instructional aid for assisting a person (11) to emulate preferred positions and/or movements in undertaking an activity by capturing position and/or movement data of the person (11) or an object associated with and controlled by the person undertaking the activity using position and/or movement sensing devices such as MEMS sensors (13) on the person (11) or object and using a computer (16) to analyze and compare the captured data with pre-stored data relating to preferred positions and/or movement in undertaking the activity and generating a visual presentation (19) based on the differences between the captured position and/or movement of the person or object and the preferred positions and/or movement and adding to the generated visual presentation, audio instructional comments relating to the differences.

Description

TECHNICAL FIELD[0001]This invention relates to a method and apparatus for providing personalized audio-visual instruction and in particular to a method and apparatus which uses sensed data coordinates of a human movement or movement of an object hi order to provide the basis for producing a personalized audio-visual teaching presentation or aid.BACKGROUND ART[0002]Accurate three-dimensional tracking of human movement has the potential to enable many kinds of human-computer interaction and vision-based methods promise tracking without encumbrance by body-mounted apparatus. The latter form of tracking can be based on the use of optical sensors affixed to a person's body however sensors of this type can become obscured and therefore accurate movement sensing is not always possible. Furthermore, setting up of a movement tracking studio using mocap cameras requires a large area, is very expensive, and for the organizations that do set up these facilities, the data collection procedures a...
