What feature allows respondents to draw their signature on devices?

The feature that allows respondents to draw their signature on devices is the Signature option. This feature specifically enables users to input their signature directly on the screen using a stylus or finger, making it intuitive and user-friendly on touch devices. It captures the signature in a way that can be stored and analyzed within the survey, allowing for a seamless experience for both the respondent and the survey creator.

Other options serve different purposes: Hot Spot is used for image-based questions where respondents click on specific areas of an image, Captcha Verification is aimed at confirming users are not bots and ensuring survey integrity, and File Upload allows respondents to submit files but does not facilitate drawing or signing. Each of these features has distinct functionalities that do not relate to the action of drawing a signature.
