VIRTUAL KEYBOARD

abstract

A virtual keyboard is actually a key-in device, roughly a size of a fountain pen, which uses highly advanced laser technology, to project a full sized keyboard on to a flat surface. Since the invention of computers they had undergone rapid miniaturization. Disks and components grew smaller in size, but only component remained same for decades -its keyboard. Since miniaturization of a traditional keyboard is very difficult we go for virtual keyboard. Here, a camera tracks the finger movements of the typist ....etc

Phase-only holographic projection has driven a great deal of research and has often been seen as a desirable method of 2-D image formation. It is superior to conventional imaging projection technology. a real-time 2-D video projection system is developed here using this system. The computational
complexity of calculating diffraction patterns has been the major hindering force for this. The poor quality of the resultant images was also a factor. This paper shows a a new pproach to hologram generation and display. Thus a
high-quality real-tim ....etc

INTRODUCTION
If you're thinking about assembling a home theatre system, you may be looking at large screen televisions as the heart of your system. Projection TV could give you the size that you want -- CRT screens generally top out at 40 (101 cm) or so, and at that size, they are huge and heavy. Plasma screens can be bigger than that and still manageable, but they can be extremely expensive. Projection TV technology can create large screen sizes at a reasonable price. Or maybe you need to equip a room, like ....etc

ROBUST VARIABLE STEP-SIZE AFFINE PROJECTION ALGORITHM SUITABLE FOR ACOUSTIC ECHO CANCELLATION



ABSTRACT

The affine projection algorithm (APA) and different versions
of it have proved to be very attractive choices for acoustic
echo cancellation (AEC). In this context, a classical APA
with a constant step-size has to compromise between two
performance criteria, i.e., 1) high convergence rates and
good tracking capabilities, and 2) low misadjustment and
robustness against background noise variations and ....etc

Automatic Gridding for DNA Microarray Image Using Image Projection Profile



Abstract

DNA microarray is powerful tool and widely used in many areas.
DNA microarray is produced from control and test tissue sample cDNAs, which
are labeled with two different fluorescent dyes. After hybridization using a laser
scanner, microarray images are obtained. Image analysis play an important role
in extracting fluorescence intensity from microarray image. First step in
microarray image a ....etc

3d holographic projection technology seminar report

Holography is the science and practice of making holograms. Typically, a hologram is a photographic recording of a light field, rather than of an image formed by a lens, and it is used to display a fully three-dimensional image of the holographed subject, which is seen without the aid of special glasses or other intermediate optics. The hologram itself is not an image and it is usually unintelligible when viewed under diffuse ambient light. It is an encoding of the light field as an interfere ....etc

Abstract
A projection keyboard is a virtual keyboard that can be projected and touched on any surface. The keyboard watches finger movements and translates them into keystrokes in the device. Most systems can also function as a virtual mouse or even as a virtual piano. A proposed system called the P-ISM will combine the technology with a small video projector to create a portable computer the size of a fountain pen.
How a projection keyboard generally works:
-A laser or beamer projects visible virtual key ....etc
