Data Glove

The data glove is a direct sibling of the original lego glove that we had been working on.

This glove (Figure 1) defines prototype. We learned a lot from this glove. We figured out how to monitor up/down motion of the wrist using bend sensors and running them into one stereo plug. Tav Hawkins figured out that we could share the ground of both of them in the same stereo plug, and face the bend sensors away from each other. It worked out great, and we got perfect data from it.

This Picture (Figure 2) has a good detail on the how the second glove's electrical backbone is wired, 3 Bend Sensors that monitor finger movements, and a double bend sensor on the top of the wrist that can monitior wrist up/down movement.

This picture has a nice display of the 3 Velostat sensors that can be used to monitor finger pressure against surfaces, or against each other as displayed in the finger pinch model above.

Patchwork has been started on the glove using iron-on patches. These patches will cover up any component of the glove that could catch on other materials. In addition, there is a superficial inhancement to covering up the sensors and wiring.

The next version of the glove is going to have 1 minor engineering change. The problem with the current glove (above) is that the velostat sensors were held onto the glove with iron-on patching, and they all came off of the fingers. The way that Dr. Warner has directed us to over come this is to use the iron-on patches in a different really neat way. After wiring the Velostat sensors, put the sensors between two pieces of the iron-on material and iron them together. Then take the iron-on-velostat sensor sandwich and sow it onto the fingers. This should create a dramatically better hold onto the glove, and more durable product.
