Abstract
Vision-based hand pointing interactive systems always assume implicitly that users’ physical pointing accuracy is perfect. However, this may not be the case. We investigated the accuracy provided by users in three pointing strategies. Result showed that pointing inaccuracy can be as high as 239mm at 3 metres away and suggest that the line-up method provides the best accuracy overall.
