Interactive displays: natural human-interface technologies

One of the first books to provide an in-depth discussion of the technologies, applications and trends in the rapidly emerging field of interactive displays (touch, gesture & voice) The book will cover the technologies, applications and trends in the field of interactive displays, namely interfaces based on touch, gesture and voice and those using a combination of these technologies. The book will be split into 4 main parts with each being dedicated to a specific user interface. Part 1 ''Touch Interfaces'' will provide a review of the currently deployed touch-screen technologies and applications. It will also cover the recent developments towards achieving thinner, lightweight and cost-reduced touch screen panels in the future via integration of touch functionalities. Part 2 ''Gesture Interfaces'' will examine techniques and applications in stereoscopic 3D computer vision, structured-light 3D computer vision and time-of-flight 3D computer vision in gesture interfaces. Part 3 ''Voice Interfaces'' will review developments in voice input, processing and recognition techniques enabling voice based interfaces and interactions. Part 4 ''Multi-Modal Interactions'' will detail the emergence of natural human-computer interactions schemes which intuitively combine touch, gesture and voice for life-like interactions. One of the first books to provide an in-depth discussion of the technologies, applications and trends in the rapidly emerging field of interactive displays (touch, gesture & voice)Provides a summary of current developments and ties this together with an outlook to future trends to offer a cohesive discussion of the field as a wholePresents a state-of-the-art view of interactive display technology, with emphasis on the technology of touch, 3D position sensing and voice recognition as they apply to visually rich information system, especially those equipped with displaysIncludes contributions from leading researcher

The Ion Capturing Effect of 5 Degrees Siox Alignment Films in Liquid Crystal Devices

We show that SiOx, deposited at 5 degrees to the interior surface of a liquid crystal cell allows for a surprisingly substantial reduction in the ion concentration of liquid crystal devices. We have investigated this effect and found that this type of film, due to its surface morphology, captures ions from the liquid crystal material. Ion adsorption on 5 degrees SiOx film obeys the Langmuir isotherm. Experimental results shown allow estimation of the ion capturing capacity of these films to be more than an order of 10 000/mu m(2). These types of materials are useful for new types of very low power liquid crystal devices such as e-books.</p

The Effect of Salt on Ion Adsorption on a Siox Alignment Film and Reduced Conductivity of a Liquid Crystal Host

It is shown that the addition of salt to liquid crystal cells, using a SiOx alignment layer, can actually reduce the ion concentration. This seeming contradiction may be explained by the ability of salt to complex with water and to aid the drying of the liquid crystal material. The results show a pathway to purifying liquid crystal devices to the extent needed for low-power low-refresh rate displays for e-book applications. </p

Design of a Wide Bandwidth Switchable Mirror Based on a Liquid Crystal Etalon

We propose the design for a switchable mirror with high efficiency and a 30 nm bandwidth. The device is based on a liquid crystal filled etalon. Broad bandwidth is achieved through the use of integrated half-wave layers into the dielectric stack design, while high efficiency is achieved using a polarization independent liquid crystal effect. Potential applications in the area of displays are also presented.</p
