Input device, display apparatus, and method of controlling input device

摘要

An input device, a display apparatus and a method of controlling the input device are provided. The input device includes: a communicator configured to communicate with a display apparatus; a sensor configured to sense a sound; a volume extractor configured to extract volume sections from the sound sensed by the sensor; and a controller configured to determine whether a peak level of each of the volume sections extracted by the volume extractor exceeds a threshold level, and in response to determining the peak level of a volume section among the volume sections exceeds the threshold level, control the communicator to generate an event signal for cancelling a job for a pattern image displayed on the display apparatus based on a touch input and transmit the event signal to the display apparatus.
