You may use a sensor. For example, if you clap the light will turn on. Also a temperature sensor, if the room you are in is cold the light will turn on or off.

The major advantage of a clap switch is that you can turn something (e.g. a lamp) on and off from any location in the room (e.g. while lying in bed) simply by clapping your hands. The major disadvantage is that it's generally cumbersome to have to clap one's hands to turn something on or off and it's generally seen as simpler for most use cases to use a traditional light switch. The primary application involves an elderly or mobility-impaired person. A clap switch is generally used for a light, television, radio, or similar electronic device that the person will want to turn on/off from bed.
