Technology has moved from a level at which a user is always present in a place before he/she can control or do anything at the place. Imagine what television used to be before the inception of remote control. With the inception of remote control, the television can be controlled while lying on the bed or sitting down on the chair. The user do not have to move towards it and press the button on it before one can control it. Now envision how it will be, being able to control their entire home appliances automatically and even remotely.
