IDEO's Social Mobiles project sought to design mobile phones that modify their users' behaviour to make it less disruptive.

Five working prototypes were developed by IDEO and designer/artist Crispin Jones.

The Electric Shock Mobile prototype attempts to reform mobile phone users who persistently disturb others with loud and intrusive conversations. It delivers a variable level of electric shock depending on how loudly the person on the other end of the line is speaking to encourage both parties to speak more quietly.
