What innovative device assists the disabled with computer pointing?

1. Graphics tablet

2. Touch screen

3. Eye-tracking device

4. Optical mouse

The correct answer is: Eye-tracking device

The eye-tracking device is an innovative tool specifically designed to assist individuals with disabilities in computer interaction, particularly in terms of pointing and selecting items on a screen. This technology allows users to control the computer by tracking their eye movements, effectively enabling them to navigate and interact with digital interfaces without needing traditional pointing devices like a mouse or touchpad. Eye-tracking devices utilize sophisticated sensors and cameras to detect where the user is looking on the screen. When the user's gaze lingers on a specific area or icon for a set duration, it can trigger a selection action, which is incredibly beneficial for individuals with limited motor skills, allowing them to use a computer with greater ease and independence. While graphics tablets, touch screens, and optical mice are useful tools in computer interaction, they may not cater specifically to the needs of individuals with certain disabilities as effectively as eye-tracking devices. Graphics tablets require a stylus and typically demand some level of hand dexterity, touch screens necessitate physical contact, and optical mice still rely on hand movement for navigation. In contrast, eye-tracking technology opens up opportunities for those who find traditional pointing methods challenging.
