To conclude this Graduation Project the research questions will be discussed once again as well as the answers given within this project. Furthermore the possible future work regarding the created application will be discussed.

8.1 Conclusion

The assignment given at the start of this assignment was to create an innovative application for the Myo. In order to do this, research was done into the Myo as well as comparable devices. There after, an application idea was formed, which was created and tested later on.

In the beginning of the project a series of research questions were asked. During the State of the Art research the first research question “In what domain(s) can the Myo provide actual benefit?” was answered.

To answer this question three subquestions were stated. The first “What are current applications the Myo is being used for?” was answered with a research into the current applications. The five identified fields were Mouse and keyboard replacement, Virtual reality, Entertainment, Robotics and Medical.

To further explore in what domains the Myo could be used a second subquestion was asked “What are possible applications for the Myo which currently do not exist?”. This question was answered with a research into related technologies and the applications related to these technologies. This resulted in the domain of Health, which encompasses both Medical as well as Sports, of which the latter was not explored much for the Myo yet.

Finally, the last subquestion “What is the added benefit the Myo provides?” was asked in order to see what benefits can be used in order to create an application in one of the found domains. This question was also answered by looking into related technologies. This time the difference in technological aspects were identified. This resulted in four unique aspects, handsfree usage, large range, battery life and the ability to read out muscle activity.

The second research question “What application can be built so that the Myo actually provides this benefit?” built further upon the first research question. The answer given within this project is a tennis trainer application. This application gives insight into the movements and power of the tennis player. This can be saved for later viewing. Furthermore, the ability to pause, play, go forward and backward into the visualisation as well as rotating around was implemented. To test whether the application proved successful a user evaluation was done. 21 people

participated within these user tests. During the evaluation a set improvements and additions were identified, which will be discussed further in the future work. Some outstanding results were, that the participants found the Myo a logical and helpful choice for tennis feedback. The participants also stated that the tutorial and calibration were the parts which could be improved the most. The final grade given for the application was a 7.2.

8.2 Future work

As already mentioned in the conclusion the user evaluation resulted in a set of improvements and additions for the created application. The most important ones will be reviewed here,. However, for a full insight into possible improvements and additions chapter 7 should be read.

The main improvements for the current application is to first provide better and more feedback. For instance, the favourite feature currently does not provide any feedback whether a favourite has been added. Also the calibration does not provide any feedback whether it has been done correctly.

Furthermore the visualisation should be improved in clarity. This can be done for instance by a human representation, which allows the user to see how the swing relates to his own body.

Another way this can be improved is by an arrow indicating which way the swing is moving, which will also be visible when the visualisation is paused.

Finally the current application can be improved by changing the workout names to the format date - time instead of the current naming. This will greatly improve the readability of the workouts. Another option here is to allow the users to alter the workout names.

Besides improvements to the application the user evaluation also brought forward additional features which can be included in future releases. Most of these features have been also mentioned within the should have and could have requirements. First is the addition of video footage linked to the visualisation. This addition would greatly improve the understanding of the visualisation making it easier to improve at tennis.

Second is the recognition of swings by the application itself. If the application can recognise the swings for the user the application becomes easier to use for new users, since it is clearer what they are looking at. This recognition also opens up the way for the final addition.

The final addition mentioned in the user evaluation is qualitative feedback. Once the swings are identified by the application, the application should also be able to compare this swing to how the swing should be. This difference can then be given back to the user in the form of feedback on where to improve.
