Assessing the overall usability of mid-air and micro-gestures issued from an armband to control video, music, or an extended entertaining environment is still a research ques-tion today. To address this problem, this paper reports on results gained by jointly conducting and comparing two user studies. On one hand, a gesture elicitation study is conducted to measure the effectiveness and the user sub-jective satisfaction of gesture interaction by participants using a Thalmic Myo armband for interacting with NetFlix and Spotify, two plug-ins developed for this purpose. This study suggests new gestures which were not identified be-fore from the initial set of the 5 Myo standard gestures, based on agreement rates. On the other hand, a System Usability Scale (SUS) focusing on the usability and the enables to identify which gestures are considered usable and desirable in this context.
