HVAC Control in the New Millenniummusic. The music, words and phrases are created by the computer.Computers also have the ability to recognize shapes. These developmentsare only the first strivings of computers to interact in a dynamic,rather than a passive way with their environment. Once a computerhas the power to recognize a shape or pattern, it can be utilizedin an emergency or fire control system which allows it to do somethingto prevent injury or harm to humans and facilities.Image recognition can take place with a robot scanning camerawhich could recognize intruders or emergency situations and control amotorized device to rectify the problem. It might also be programmedto understand a few useful words such as start, go and stop spoken byany human voice.Computer EvolutionThe computer revolution rides on the cost-tails of successful products.There is always another generation of devices capable of tacklinga far wider range of tasks. The number-only keyboards and numberonlydisplays of early calculators were replaced by full alphabeticalhand-held personal computer devices.The main difficulty of minuscule keyboards will be overcomewhen speech recognition systems shrink down to the point where theycan be built into wristwatches and other small devices. Buttons as inputmechanisms then become largely redundant. Calculations will be performedand telephone numbers and other data are entered into thememory by spoken instructions.Computer voice output is also in an extremely rapid phase ofdevelopment and speech synthesizers are diminishing in size and cost.One of the first applications was a talking calculator, which not onlydisplayed the results of the calculation on its display but also offeredthem aloud in a synthesized voice.Instruments may speak their measurements and containers maytell you how much they have in them. Talking altimeters and airspeedindicators may be used in aviation. In the home there will be speakingbathroom scales, freezers that remind you to restock them, ovens thattell you how the roast is doing, doorbells that specify how many visitorsyou had and when they came and thermometers which advise you whatto wear before you get up.
