Abstract
An operation judgment method for an interactive touch system, which is applied by a first electronic device in cooperation with a second electronic device. The first electronic device receives a projected image from the second electronic device. The projected image is displayed on a display surface of the first electronic device. The operation judgment method includes steps S1 to S3. Step S1 generates a plurality of touch feature information corresponding to a plurality of touchpoints according to a touch action. Each touch feature information includes a plurality of eigenvalues, and the touch feature information is stored in a touch register module, wherein the first touch feature information of each touch action is the initial touchpoint. Step S2 sequentially analyzes the touch feature information to generate a first command or a second command.
