Digimood PED concept

The Digimood PED (which stands for Personal Emotion Digitizer) concept is kind of like a digital mood ring. Worn on the wrist, it reads the owner's mood, changes color and shows words on the display. The concept intends for all communicators to have a device. Though I also think the PED can be removed from its bracelet and given to a loved one so they always know how you're feeling.
