![]() ![]() The Radio Frequency (RF) Remote Controls are the handheld devices that use radio frequency transmissions. The flaw is overcome by Radio Frequency Remote Controls. The shortcoming of this remote control is the need to point the remote control in the direction of its electronic gadget. The low-frequency light beams emitted by remote controls are invisible to the human eye, but the receiver in the TV set could detect it. By the 1980s, the remote controls with infrared light beams became popular. It also lets the user change the colour of their TV screens.Īfter 25 years of Ultrasonic remotes, Infrared Technology became the focus. It had multiple buttons for different functions. The processed sound waves switched the TV on or off, or changed the channel, or mute or unmute the sound. In Space Command Remote Control, the high-frequency ultrasonic sound waves were generated using aluminium rods, and the receiver in the TV set picks it up. ![]() This type of remote control was called the Space Command Remote Control. In 1956, Zenith Radio Corporation found even more efficient technology – the use of ultrasonic sound waves rather than the light waves. The receptors responded to other light sources like bulbs and sunlight. This pioneering achievement had its limitations. The remote control had a directional flashlight that could activate the photocells which would switch the sound and video on or off, or change the channels. It was operated with the help of four photocells – one in each corner of the TV screen.

The remote was wired, and the cable ran from the TV set to the viewer, meandering across the living room. The result was the Lazy Bones Remote Control. He challenged his engineers to create a device that can mute the TV and change the channel at his comfort. ![]() The man was Eugene F McDonald, the president of Zenith Radio Corporation. The first TV remote control came to existence because of one man’s desire to mute the commercials. It was the size of a dictionary and, hence, was not portable. Being the most innovative invention of its age, the Philco Mystery Control looked like a rotary telephone without the handset. It operated on radio frequencies and was used to control the household radio. The Mystery Control Remote System was invented by a company called Philco in the 1930s. Today, let us look at the history of the remote control and its journey. But do you know how remote controls have evolved over time? From a wired appliance to a space command appliance, its journey has been amazing. Since its first invention, remote controls have made our lives easy by being that little gadget that has made TV viewing seamless, to begin with. No surfing through the TV channels at the comfort of the couch!Įlectronic gadgets had to be turned on and off manually, every time!
