Abstract: Various methods for motion gesture recognition are provided. One example method may include receiving motion gesture test data that was captured in response to a user's performance of a motion gesture. The motion gesture test data may include acceleration values in each of three dimensions of space that have directional components that are defined relative to an orientation of a device. The example method may further include transforming the acceleration values to derive transformed values that are independent of the orientation of the device, and performing a comparison between the transformed values and a gesture template to recognize the motion gesture performed by the user. Similar and related example methods, example apparatuses, and example computer program products are also provided.
