Abstract

The number and quality of smartphones on the market has dramatically raised lately. Researchers and developers are, thus, more and more pushed to bring algorithms and techniques from desktop environments to mobile platforms. One of the biggest constraints in mobile applications is the fine control of computing power and the relative power consumption. Although smartphones' manufactures are offering better computing performance and longer battery life, the mobile architecture is not always powerful enough. Furthermore, nowadays, the touchless interaction (e.g., the usage of voice commands) on mobile devices is particularly attractive. The device can also possibly answer to our questions (e.g., Siri-Speech Interpretation and Recognition Interface, which according to Apple is "the intelligent personal assistant that helps you get things done just by asking"). The use of talking avatars can improve the quality of the interaction and make it more useful and pleasant. Since avatars are static models, but the interaction requires dynamics, it is almost obliged to introduce avatars' animations.
