Answer: (a).They can be expensive and it can be difficult to distinguish deliberate gazing from accidental glancing. Explanation:While eyegaze systems offer a unique and hands-free way to interact with a computer, they do present some challenges. First, these systems can be quite expensive, particularly the more accurate versions. Second, in practical applications, it can be difficult to distinguish between a user deliberately gazing at something on the screen and accidentally glancing at it. This could potentially lead to unintended commands being given to the computer.
