7. Mobile User Interface

• Description:
  

Mobile handsets are limited on their hardware features unlike big wired devices. For example, smaller screen and memory capacity, lower CPU speed, etc. As a result, mobile handset UI has been poor and required advanced technologies in the area of voice recognition, key input methodology, platform and service UI, etc.

• Enablers:
  

1. Technical progress in user interface area like voice recognition, key input methodology, platform and service UI, etc.
2. Enlarged H/W features such as CPU power and memory.

• Inhibitors:
  

1. Retardation of UI technology
2. Low CPU power

• Paradigms:
  

1. Old: Users should hold their device and press keys to handle them.
2. New: Users can handle their devices in voice during driving the car and leaving them on the desk or shoulders.

• Timing:
  

2001: MIC(Ministry of Information and Communication) found SIPIC(Speech Information Processing Industry Committee) and constructed common speech database
2003: Enlarged SIPIC to Korea Speech Information Technology Industry Association
2005: Registered speech Information technology R&D centers in universities, Korea.
