Haptics
Research
Haptics involve feedback technologies using the sense of touch by applying forces, vibrations, or motions to devices. It takes advantage of your sense of touch and feeling to communicate information about the environment you wish to control with a computer. It creates a special type of communication which responds to "touch" as you interact with virtual objects.
Advantages
We can design better gaming experiences and massage machines Because it uses the sense of touch, it gives better communication about feelings
Risks
The hardware can harm people if broken, and is expensive to replace.
Media
Application for Solving World Hunger
Haptic technology can be used to centralise the control over the entire farm in one place (control room) this will make 1 man be able to control the entire farm. All parts of the farm could be centrally controlled from anywhere in the world. So fewer workers are required.
