Interactive Displays: Natural Human–Interface Technologies

How we interface and interact with computing, communications and entertainment devices is going through revolutionary changes, with natural user inputs based on touch, gesture, and voice replacing or augmenting the use of traditional interfaces based on the keyboard, mouse, trackballs and joysticks. As a result, displays are morphing from one–way interface devices that merely show visual content to two–way interaction devices that also directly receive natural user inputs and, thus, provide more immersive experiences. This book provides an in–depth coverage of the technologies, applications, and trends in the rapidly emerging field of interactive displays enabled by the natural interfaces. Key features: Presents a state–of–the–art review of interactive display technologies, with emphasis on natural interfaces using touch, vision, and voice recognition as they apply to interacting with visually rich information displays and systems. Provides an in–depth reference reading on all the touch technologies and applications, and developments towards achieving thinner, lighter, and lower–cost touch–screen devices. Details the techniques and applications in vision–based user inputs, with emphasis on 3D sensing and interaction technologies, and their applications in the emerging interfaces using the gestures of hands, body, face, and eye gazes. Covers the fundamentals and developments in voice input, processing and recognition techniques enabling voice based user interfaces and interactions. Discusses multi–modal interfaces and the emergence of natural human–computer interaction schemes which intuitively combine touch, vision, and voice for life–like interactions. Examines the requirements and technology status towards achieving the future “true” 3D immersive and interactive displays.
