Abstract:The Myo armband by Thalmic Labs allow the user to control application by means of movement and gestures. These gestures are measured using EMG to measure the power exerted by the muscles. Furthermore, the movement is measured using an Inertial Measurement Unit. Currently quite some applications have been made for the Myo, however there is still enough room for the development of unique applications. To explore what unique applications could be made for the Myo a research question was formulated, being: “In what domain(s) can the Myo provide actual benefit?”. This question has been answered with a state of the art research into the current applications for the Myo as well as a research into related technologies to the Myo. The application domains for the Myo are found to be Mouse and keyboard replacement, Virtual reality, Entertainment, Robotics and Health. Where Health consists both of Medical and Sports. The actual benefits provided by the Myo are identified to be handsfree usage, large range and battery life as compared to the LEAP Motion, Kinect, Fitbit and more. The first research question provided the basis for the second research question: “What application can be built so that the Myo actually provides this benefit?”. This research question has been answered using the Creative Technology Design Process which consists of an ideation, specification, realisation and evaluation phase. The ideation phase resulted in three possible applications a guitar trainer, a remote smart screen control for teachers and a tennis trainer. using the unique aspects of the Myo and via interviews the choice was made to create the tennis trainer application. The specification phase provided the basis for the application. Using a functional analysis, system architecture and a requirement analysis the application was given form. The most important requirements formulated here were the usage of the Myo, the visualisation of power and movement and storage of the workouts. The realisation phase covers the creation of the final prototype. Before this prototype was made a set of Lo-Fi prototypes was created to explore certain functionalities of the final prototype. Afterwards the final prototype was created which implemented the requirements and system architecture formulated in the specification phase. In the final phase, the evaluation phase, the Hi-Fi prototype was tested using user evaluations. 21 people with an age range of 18-25 years old participated within these user tests. The overall result was that the application was received in a positive manner with some specific points being that the choice for using a Myo as sensor input was found logical and not hindering. The average grade given by the participants was a 7.2. Future development into the application would involve the improvements on the feedback of certain functionalities, such as the calibration and favourite feature. Furthermore, visualisation of the tennis movements can be made clearer. Also the workout names should be improved. Additional features of the application would include the addition of video footage, the recognition of swing types and qualitative feedback upon these swings.
