Augmented reality phone
Shown here is a phone from Kyocera's booth, called "Organic Transparent." This concept features an flip-out sheet of glass that is supposed to serve as an "augmented reality layer." The idea is that it can act as a screen on which information about businesses or a landmark it's pointed at can be projected.
Mobile 3D video
Each gets a heart that they grip in their hand. The device measures pulse, which is supposed to represent how fast your heart is beating while talking on the phone to your sweetheart. The info from the hearts is sent via Bluetooth through the phone to the other person's phone and then to his or her own heart. When the heart heats up, vibrates, or its lights change colors, it's meant to communicate how a person's partner is feeling about them at that moment.
