Abstract
With the increased dependence on electronic devices as the primary mode of communication, there has been an upward tread on increased sophistication and complexity of these devices. The development and production of the most convenient and best input hardware has been a major field of exploitation by developers. Virtual laser keyboard has been a major breakthrough in this field. The keyboard which is non-physical has brought a new dimension in the field of data entry where the mechanical keyboards can be replaced by a light beam projected on a flat surface. It replaces the physical key board which occupy space on the devices. This paper focuses on the virtual laser keyboard as a revolutionary invention in multimedia and data entry industries. The paper looks on what should be done in order to globalize the user of this virtual keyboard while it also focuses on the limitations that are associated with this technology.
Key words: miniaturization of devices; virtual laser keyboard; CMOS; sensor chip; red diode. Introduction
Communication, an important aspect of our lives would be less streamlined without devices such as computers, laptops and mobile phones. All these devices require the user to feed it with information and instructions through an input device. A keyboard is the major input device to these electronic devices. Daily people use it when composing mails, perform searches through the web, creating word processing document and sending texts in a mobile phone with a three-by-four keypad (Fuller 2011). It is amazing to see how people in trains, classrooms, in the streets use the keyboard showing how important crucial for communication. In fact, without a keyboard, it would have been impossible to create this document. With the increased miniaturization of hand held devices, smaller and smaller keyboards are being developed. The problem is that the users’
