A gesture is used to classify and recognize a signal that enables communication among the impaired community. It is a technique that has been in use to make people feel comfortable just like the normal people behave. In this article, the communication toolkit comprises a gesture recognition kit that comprises of an audio device, a display selective panel and an eyeglass with inbuilt camera. The...

A high contrast electroluminescent (EL) device structure is presented. The diffuse luminous reflectivity from the metal/dielectric/phosphor/indium-tin-oxide/glass EL device structure is 3%. A Eu-doped GaN phosphor is used to demonstrate the contrast-enhanced operation. Low reflectivity is achieved by inserting a light-absorbing black thick-film BaTiO3 layer between the phosphor and the rear met...

Polymer Light Emitting Diodes, the most promising name in the field of display technology has received tremendous attention from various research groups. Being an interdisciplinary area of research, there has been challenging experiments on material science, device physics and chemistry of this organic display. This review unveils the development of PLEDs from its inception, bringing out import...

We developed a device that converts visual information on a tablet into tactile information on the fingertip. To achieve this we mount optical sensors and a tactile display on the fingertip. Our first prototype using a vibrator for each finger revealed that it was difficult to recognize the information of the display, mainly because of its low resolution. We addressed this limitation in our sec...

The principal channel of interactive communication from a computer to a person is an electronic display. The amount of information shown and the way in which it can be exhibited depend on successfully matching the capabilities of the display to the human visual system. Making this channel as wide, as fast, and as effective as possible has been the goal of electronic display development for the ...

This article introduces the design and implementation of an Android-platform based calculator, which can recognize the formula captured by a mobile phone camera, compute the result, and display it on the screen. This application enables a faster calculation on a mobile device by avoiding inputting the formula to some device. Keywords-formula recognition; OCR; Android

The PARIS (Personal Augmented Reality Immersive System) is a new VR display device that was first prototyped as a virtual device in a CAVE, to aid in the development process. This initial prototyping in VR allowed the designers to save time and money, and to garner valuable feedback from prospective users, before finally committing the design to hardware.

Despite the limited power available in a battery-operated mobile embedded system, its display must have an enough resolution and sufficient color depth to support quality graphical user interfaces and multimedia applications. An LCD (Liquid Crystal Display) is a standard display device, and a color TFT (Thin-Film Transistor) LCD is common even in a low-cost equipment. An LCD display system is c...
