ITPEC IP April 2023 Question 11
ITPEC IP April 2023 — Question 11 of 100
A touch panel detects direct contact with the display surface, and common types include resistive and capacitive panels. It combines visual output with positional input, allowing a user to select, drag, type, or gesture by touching items shown on the screen. Resistive panels detect pressure between layers, while capacitive panels detect changes in an electric field.
Answer (d)
Why not others:
- (a) describes a graphics tablet or digitizer used with a pen or pointing device
- (b) describes a touchpad, which controls a separate on-screen pointer
- (c) describes a wheel-based pointing or control device rather than direct screen contact
Key rule: A touch panel is both screen and positional input surface; a touchpad or tablet is a separate input device.
