Customizing Lip Video into Animation for Wireless Emotional Communication
2004 (English)Report (Other academic)
Universal Multimedia Access (UMA) engines are used to adapt the media content to suite different environments.
The adaptation decision for content used over wireless networks is heavily dependent on the bandwidth needs since the transmission cost over wireless networks is high. We customize lip video into lip animations and through tests we challenge the assumption that the quality is reduced when the transmission cost is reduced. We show that animations are comparable with video when considering human emotion understanding and comparable with audio only when considering transmission cost. We argue that it is important to consider human cognitive and perceptive factors in the decision stage of a UMA engine. This can both improve the user’s perceived quality and lower the transmission cost.
