Abstract

The identification of postural transitions and walking patterns are important in the recognition of activities of daily living. This paper presents a feasibility study to see if postural transitions and walking patterns can be identified using a wrist-worn accelerometer-based device. Firstly, the postural transition (i.e. sit-to-stand and stand-to-sit) templates are extracted and template matching is used to identify the transitions between daily living activities such as walking within a house. Secondly, the various walking patterns such as walking on a level surface, walking up the stairs and walking down the stairs are classified using statistical features and nearest neighbor classifier. A comparison between the activity pattern from the dominant wrist and the non-dominant wrist is also presented.
