Meeting decades of computer science and computer engineering research in multimodal interaction (eg, speech and gesture recognition), machine learning (eg, classification and feature extraction), software (eg, web browsers, distributed agents), electronics (eg, energy-the microprocessor Efficient, head-mounted display), the design methodology in a user-centered design and rapid prototyping have enabled a new class of computer? wearable computer. lectures take the perspective of a potential designer or researcher in wearable computing. Designing a wearable computer requires attention to various factors because the computer s proximity to the body and its use? while performing other tasks.
