Computing is now not limited to desktops and laptops, it has found its way into mobile devices like palm tops and even cell phones. But what has not changed for the last 50 or so old years is the QWERTY keyboard. Virtual Keyboard uses sensor technology and artificial intelligence to let users work on any surface. Virtual Devices have developed a flashlight-size gadget that projects an image of a keyboard on any surface and letâ€™s people input data by typing on the image. The Virtual Keyboard uses light to project a full-sized computer keyboard onto almost any surface, and disappears when not in use. The VKEY provides a practical way to do email, word processing and spreadsheet tasks.
The new virtual keyboard technology uses sensor technology and artificial intelligence to let users work on any surface as if it were a keyboard. Virtual Keyboards lets you easily create multilingual text content on almost any existing platform and output it directly to PDAs or even web pages. Virtual Keyboard, being a small, handy, well-designed and easy to use application, turns into a perfect solution for cross platform multilingual text input.
In this paper, we survey the state of the art in alphanumeric input interfaces. After an overview of the related work in the area in section 2, we lay out the general space of interfaces for alphanumeric text input in section 3. In section 4 we discuss characteristics and human factors of touch-typing in particular. Section 5 introduces some touch-typing input methods and devices. We conclude with stating that keyboards whether virtual or real are very well suited to the task of alphanumeric input.
