After soldering all the equipments, it turned out that the delays in the operation of our device are caused by power consumption problems. Because of this reason we had to regulate the Neopixel ring's power consumption. As we recognised this problem quite late (little before the demo), the easiest solution was to set its brightness lower. A better solution could have been to supply energy for the Neopixel ring directly from the battery. In this way we could have kept its brightness, but it would have required more soldering which we didn't have time for.
Another fast change what we had to make was the relocation of the RFID reader from the finger to the inner side of the wrist, because of the reasons which were mentioned in a previous post. As a result of this the concept has also changed. From now on the interaction was only limited to hugs, rather than allowing every kind of touch.
The last challenge was to find out where to place the RFID tags to sense the different hugs. For this we conducted a fast 'research'. We asked around 15 people to give a hug to Shachi and we signed the wrist positions on his back. It was really interesting as we got really different result than what we expected. So we had to relocate the already placed RFID tags :)
