Developing a Mobile Application for an Abdominal Exercise Machine Using an Accelerometer

This paper proposes a method of developing a mobile application for an abdominal exercise machine. Currently, inexpensive exercise machines, which are sold internationally, do not give feedback to users about the workout they engage in. Therefore, it would be useful to develop an app that could monitor physical activity on low-cost exercise machines. An additional benefit of using smartphones is that the exercise data can be cast to larger TV screens and monitors. Leg raise and lower cycles, as well as the number of back raise and lower cycles, were determined from angles measured by smartphones equipped with accelerometers connected to the bars of an abdominal exercise machine. In addition, an Android application for abdominal exercise machines was created based on the method. The app allows users to monitor their abdominal exercises by setting parameters related to raising and lowering their legs and the backs of their bodies. The results of physical activity were displayed on a smartphone screen and spoken using Text to Speech technology.
