Figure IX-1, Clinical task, the participant is asked to perform a PIP joint angle alternation of 90 degrees, 110 degrees, 140 degrees,  150 degrees, and 180 degrees for a few minutes. The sample data fit for the PIP joint angle during clinical tasks.

Figure IX-2, Typing Keyboard, the participant is asked to type on a Mac keyboard for a few minutes. The stable interval and fast angle change period fit the practical situation. The range of PIP joint angles fits the actual situation.

Figure IX-3, Walking, the participant is asked to walk freely for a few minutes. Our algorithm shows a sufficient anti-interference performance in light movement. The PIP angle didn’t change much in that period. It fits the practical situation. However, at the beginning of this task, the distribution from the body movement alternates the PIP joint angle. The data is not accurate in that period.

Figure IX-4, Playing Piano, the participant is asked to play the piano for a few minutes. The range of PIP joint angles fits the practical situation. Since it is a relatively intensive exercise, the PIP joint shows a relatively large range of movement. The participant’s finger degree of freedom doesn’t reduce significantly. 

Figure IX-5, Holding Smartphone, the participant is asked to hold the smartphone for a few minutes. It shows a relatively stable PIP joint angle. Our plot fits the practical situation. 

Figure IX-6, Writing, the participant is asked to write for a few minutes. It shows a relatively stable PIP joint angle. Our plot fits the practical situation.
