Headset uses ear muscle signals for hands-free control – CES 2015

The video explains how individuals with spinal cord injuries can control devices using muscles around the ears, which are innervated by cranial nerves. These muscles generate electrical signals that sensors detect and transmit to a wireless device. This device translates the signals into commands to operate wheelchairs, computers, or keyboards.

Which muscles are used to control devices in individuals with spinal cord injuries?

• Muscles around the eyes

• Muscles in the legs

• Muscles around the ears

• Muscles in the arms

What type of nerve innervates the muscles around the ears?

• Autonomic nerve

• Spinal nerve

• Cranial nerve

• Peripheral nerve

What do the sensors detect from the muscles?

• Chemical signals

• Electrical signals

• Thermal signals

• Mechanical signals

What is the role of the wireless device in this system?

• To control muscle activation

• To translate signals into commands

• To detect muscle movement

• To generate electrical signals

Which devices can be controlled using the translated commands?

• Wheelchair

• Refrigerator

• Microwave

• Television
