MYO – Initial thoughts and concerns

In an attempt to get our hands dirty with trying the MYO for the very first time, we realized that we share a love-hate relationship with it ( I shall quote you on this , Wallace). We were sincerely impressed with the simplistic design and hassle free set-up. A simple low energy Bluetooth dongle and a connecting application along with a very simple but powerful getting started guide was all it took to discover all of its functional capabilities. We were very much driven to validate our design ideas by exploring the gestures further.

As impressed as we were, We wrote our own sample application to understand the actual troubles. This was when we found out that calibrating the MYO is a very crucial step in getting it to work for any further application and This was not in anyway easy or obvious . The getting started guide was so well presented as to (deceptively?) make it all look so easy.

Once we had the sample application, We tried to see if our gesture mappings still made sense and if the design would still work . The problem of false positives, false negatives with the pose being misread or simply going undetected is of concern although we believe that calibrating the MYO very carefully should address this issue significantly if not completely solve it.

The idea of using 3 of 5 poses recognized by MYO in the core activity of symbol selection, and the other two poses for committing the symbol selection and committing the word selection each seems very much feasible, but we still need to address the question of auto completion at a word level and more importantly the visual deign of the layout. This is because the MYO is on the higher end of the sensitivity, and it essentially means that users will need to depend(heavily) on the visual cues , at least initially , in order to get accustomed to the sensitivity and to avoid erroneous symbolic input.

So, we plan on making the visual representation more effective while also trying to balance the sensitivity of the MYO and also maybe allow a different correction mechanism (rotate arm in intended direction ) without having to use backspace (spread fingers gesture).
