What is PC Eye?

PC Eye is an eye-tracking system that is mounted on a computer screen or tablet and enables users to control and communicate with the device through eye movements. It is primarily used by people with physical disabilities who are not able to operate a mouse or keyboard.


How Does It Look?

A long thin bar-like machine situated below or on the screen.

Equipped with infrared cameras and sensors that track eye movement.

Usually light in weight so that it is easily carried around.

Connected to the computer through USB cable.


How to Use It:

1. Install the PC Eye unit on the screen bottom through magnetic mount.

2. Install Tobii software called Communicator 5 or TD Control.

3. Calibrate the system by following on-screen dots with your eyes.

4. After calibration, we can use your eyes to operate cursor

  *Click using blinking, dwelling (staying focused on a point), or external switches

  Type on an on-screen keyboard, speak pre-recorded messages using speech software


Who Can Uses It?
  • Individual with limited motor control
  • Individual with neurodegenerative diseases
  • Non-verbal individuals using communication devices.
  • Individual who suffers spinal cord injuries


Advantages of PC Eye:

1. Hands-Free Control

Allows users to operate a computer solely by eye movements, and it is ideal for individuals with no or little hand movement.

2. Increase Independence

Allows users to browse the web, type, communicate, and even play games on their own—without the help of a caregiver.

3. Accurate and Responsive

Offers highly precise eye-tracking for cursor control, even for individuals with very minimal head movement.

4. Access to Education

Empowers physically disabled pupils to engage with digital learning, write examinations, complete assignments, and use creative software such as drawing or coding.



PC Eye Disadvantages:

1. Costly

The software and equipment required are expensive, which may limit access by some individuals or schools without some sort of financial assistance.

2. Installation and Training Required

Initial installation will likely need the help of an expert, and users will likely need training and time to accommodate the system.

3. Sensitivity to Lighting

Bright sunlight or poor lighting circumstances can interfere with eye-tracking accuracy.

4. Eye Fatigue

Prolonged usage can cause eye strain or fatigue, especially in first-time users.

5. Not For All

It becomes increasingly challenging for individuals who have uncontrollable eye movements, poor eyesight, or mental disability to utilize.
 

 Benefits in Education:

  Equal access to learning: Gives disabled students access to digital learning aids class engagement.

  Improves communication: Enables students to communicate with teachers and friends via speech generating software.

  Empowers independence: Enables homework, surfing, and research independently of physical support.

  Boosts confidence and motivation: Independent device control gives a sense of belonging and motivation.

  Personalized learning: Educators can adjust learning apps and environments based on the student's needs and pace.

YouTube provides good images and animations that allow learning to be more fun and memorable. It also helps students learn independently. Like sometimes we can give t...
