Experiments and scenarios ,[object Object],[object Object],[object Object],Jun 2, 2009 Davide Del Monte - www.diplod.it - Management Engineering @ unimore All 23 pick up / put down events were detected, all 3 motions with an object were detected, and all 4 hand-waves were correctly labeled as occlusions: 100% accuracy by the algorithm. No false positives occurred. ,[object Object],All 9 pick up / put down events were detected, and one of the 3 placements were detected: the other two were not. No false positives occurred. Overall, 10 of 12 events were detected, for an accuracy of 83%.

Other studies Jun 2, 2009 Davide Del Monte - www.diplod.it - Management Engineering @ unimore A Scalable Approach to Activity Recognition Based on Object Use “ The ability to recognize human activities from sensory information is essential for developing the next generation of smart devices. Many human activity recognition tasks are — from a machine learning perspective — quite similar to tagging tasks in natural language processing.” From Relational Transformation-Based Tagging for Human Activity Recognition
