Emergency calling shortcut is a mobile application with the aim of helping the visually impaired or blind people to make emergency phone calls, however, it can also be useful for anyone. The proposed calling procedure is more agile than the conventional one. With this application it is not necessary to unlock the phone neither request its execution on the Smartphone because it runs in the background. It consists of a combination of simple cell phone movements to call three previously saved different phone numbers. The innovation of this work is the use of the accelerometer to interact with the user, combined with the proximity sensor to avoid undesired calls. As far as we know, this application is unique in its way of operating and more robust than those that use the on/off button since it is practically impossible to make calls without the user requesting it. Applications that use the on/off button sometimes make undesired calls.
