As human beings, we are inherently trained in the perception of life-like signals. It may therefore be worthwhile to investigate such signals as a means of status display for mobile phones, which currently only communicate with us through beeps and vibration bursts.

The common relationship to one's mobile phone is already a close one. This project exaggerates this circumstance, by proposing a permanently active, yet subtle, tactile impulse as a status display: A calm pulse that represents a status of 'no missed calls, no missed text messages, and a sufficient niveau of battery and reception', and, respectively, a excited pulse that issues the phone's need for attention. The project involves a number of breathing and pulsating prototypes.
