Designers Kiki Tang and Daniel Yoon describes
"It is of course touch based and all the user’s connections are shown graphically so you can see who is connected to whom. Each contact has an avatar that is encompassed by two colored rings. The inner colored ring shows the contact’s previous emotional state, and the outer ring represents the contact’s current emotional state. It is important to show the shift in emotions in order to see how an event has affected that contact.
Another important feature that we felt was important was the “Emotional Health Chart”. This chart would monitor the user’s emotional health through an indefinite period of time. One would be able to see how a certain event, or phone call/ message has affected the user. Obviously, if the chart shows someone is always upset, there would be a problem… If permitted, a user would be able to view other user’s charts as well.
The phone is used in conjunction with a biometrics ring that is worn by the user to collect “emotional data”. Spec-wise it features a transparent OLED screen that remains transparent when not in use and turns opaque during interaction. The front of the device is a full touch screen surface, while the back has a physical keyboard.
Considering how RIM Blackberry is flagging a bit in the face of iOS and Android phones.
