Recently, the researches of activity recognition with sensor data are increased by the spread of smart phones with 3-axis accelerometers and gyroscopes. However, gathering various sensor data from many people is difficult. To solve this problem, we developed activity gathering platform using various client software. Moreover, annotating the data of continuous activ- ities is also an important task. However, this task requires a large amount of it is done by hands. Moreover, an activity has a complex structure, and annotation by human often contains ambiguity. For this reason, a system needs to support so that a worker may add annotation efficiently and correctly. Therefore, we propose the annotation software which has the function of hierarchical segmentation and hierarchical annotation as a precise and invariant method.
