Claim 6:
7. The method according to claim 6, wherein the orientation data further comprises a deviation angle that is of the terminal and that is from a preset coordinate axes in the preset coordinate system, and the performing normalization processing on the orientation data to obtain normalized data comprises:
performing normalization processing on the deviation angle according to the following formula to obtain normalized data:, Normalized
