These data consist of x as one muscle and y as the other. The muscles are at the bottom of each picture.

Diagrams of Recorded Muscles

So far, we have recorded EMG signals from three fingers. Below are the diagrams for the three muscles we have recorded, highlighted in green. They are extrinsic muscles, responsible for the extension of fingers but located in the forearm.

Extensor Digiti Minimi: Responsible for pinky extension.

Extensor Digitorum: Responsible for the extension of the four fingers, not including the thumb.

Extensor Pollicis Brevis: Responsible for the extension of the thumb.

Progress Report: 3/10/16

For the past few weeks, We have been collecting data for the different muscles that we need to analyze. So far, we have recorded the data for all five fingers for Extensor Digiti Minimi and Extensor Pollicis Brevis.

These past few weeks we have been also working on finding a way to separate the points

This is the graph we gathered. The x coordinate was Extensor Digiti Minimi and the y coordinate was Extensor Pollicis Brevis.

From the graph, we can see that there is a clear difference between the thumb and the other fingers. This is what we predicted because the thumb's movement is caused by an entirely different muscle while the other fingers are all intertwined and are moved by common muscles. Now that we have this, we are going to work on differentiating the other fingers so we have to now start dealing with 3D and 4D.
