Using Triz To Design The Future Keyboard, Umakant Mishra
Using Triz To Design The Future Keyboard, Umakant Mishra
Umakant Mishra
A keyboard is the most common and widely used input device for a computer. Using the keyboard is often vital to interact with a computer. There are several aspects of a keyboard such as size, key layout, convenience and ergonomic features etc., which are continuously under improvement by keyboard designers and manufacturers. TRIZ is an efficient methodology in product designing. Using IFR and Trends we can well predict the directions of the future keyboards and using Contradictions and Principles we can overcome the current limitations. This article analyses the critical features of a keyboard, does a functional analysis, derives the …

Although directional antennas have been used in mobile communications systems for quite a long time, realistic applications of directional or smart antennas in wireless ad hoc network have emerged just in recent years. Directional antennas provide numerous benefits, such as higher gains, increased transmission range and low interferences. Wireless medium access schemes play a crucial role in ensuring the efficient and fair sharing of wireless resources. Therefore there are many research work on mechanisms at the wireless medium access layer by using directional antennas. The new features of MAC with directional antennas can cause not only location dependent carrier sensing …
