The document discusses a study that evaluated the use of a MYO armband wearable device for hand gesture navigation in an Apple Maps application. A questionnaire was administered to 23 participants who used hand gestures like spreading fingers, waving left/right, and making a fist to perform common map navigation tasks like zooming and panning. Results showed that while most users felt comfortable with the device, they also found the gestures difficult to learn and use. Participants reported high levels of effort and stress associated with each gesture type when navigating the map. The study aims to understand user experience characteristics that can help design effective applications for this type of wearable gesture input device.
