CESTUS

During the week Tom has written a Matlab code script that can detect which sign we are making with the glove in theory. We tested the code with the glove. The code worked but was fairly inaccurate. We then recorded some more values to try and make the program more accurate

We have began recording the different sign language gestures and storing the results in tables. At first one of the flex sensors was giving irregular readings because the contacts were touching another flex sensor and shorting it. The sensors were repositioned slightly.

We tried reducing the significant figures but it made hardly any difference. We noticed that the noise level in our circuit had decreased from the previous week. We think that the noise might have been caused by another project with our long wires acting as antennas. We have marked where the flex sensors will go on the glove with a marker pen, we have attached all of the flex sensors to the appropriate positions on the glove using super glue. We have attached the circuit board to the glove using a hot glue gun.

We are coming to the conclusion of this 5-week project, today we shall be glueing the flex sensors to the gloves and recording results from the gesture movements of this flex sensors. Everything seems to work perfectly so far already, we've tested the codes and Matlab codes to ensure that everything works fine and seen the plots.

Jonathan Sims , in charge of this design drew the placement allocations for the flex sensors in order to help when we decide to glue the flex sensors to the gloves. This was done using visible markers on the gloves. There was a test glove where we glued some of the flex sensors to test the effect and the flexibility of the glue when we do decide to do this on the real gloves. Glove Color: Grey and Black
