Staying mobile is very important for the quality of life, but is anything but simple when getting older. The research project inDAgo, a project initiated by research facilities in and around the city of Darmstadt, Germany, targets this problem. A first result of this project is the HelpMe application (app). By means of this app, elderly people can easily transmit in difficult situations a call for help to a network of trustworthy people willing to assist. They then receive quick and uncomplicated support by helpers in their vicinity.engamificationinDagoelderlymobileapplicationUser Experience DesignPrototypingInteraktionsmodellierungMobile und ubiquitäre InteraktionText/Conference Paper
