Got an Itch? Let Your Chair Do the Scratching
The itch chair, designed by Dana Gordon and Alejandro Zamudio Sánchez, is a futuristic chair that scratches the back of the sitter.
"Scratch underneath this four-legged friend and feel how the motion is mapped and scaled up to your own back.
The user, moving a fingertip across a touchpad located under the seat base, controls the position of the scratching actuator and its intensity. According to the scratching on the hidden pad, the chosen mechanical fingernail (connected to a servo motor) moves around the back of the chair and provide the necessary scratch."
