IoT devices which display life-support information to users is increasing. However, it is difficult to add information-giving function to the product which close to user’s life, i.e. commodity. In fact, this information is given from the device which have a wealth computation source. In this research, we propose the approach which add information-giving function to those IoT introduction difficult things, using augmented reality technology. This system enables right things to give right information in right timing.
