It is primarily voice-activated, has only three buttons, and minimal function: send/receive calls and text messages. To send text, Speech to Text Transcription system is used. The three sliding buttons are made of Polycarbonate plates with OLED screens, and an LCD screen under the buttons shows detailed messages and directions. Users slide the plate with a shown indicator upward. The outer screen communicates between users, while the inner screen communicates between user and phone system.
