Projection device and a control method thereof

A projection device electrically connected to a signal source, comprising:

• an identification module, configured to generate identification sensing data;
• a determining unit, electrically connected to the identification module, configured to receive the identification sensing data in response to the projection device implementing a gesture identification function, identify a gesture content based on the identification sensing data, and generate a control instruction based on the gesture content;
• a control module, electrically connected to the determining unit, configured to receive the control instruction and determine a command channel object of the control instruction;
• an interface module, electrically connected to the control module and the signal source, configured to receive input data from the signal source and the control instruction from the control module, wherein the interface module is configured to transmit the control instruction to the signal source to enable the signal source to operate according to the control instruction;
• a signal processing module, electrically connected to the control module and the interface module, configured to receive the control instruction from the control module and the input data from the interface module, generate at least one of projection data and audio data based on the control instruction and the input data, wherein the command channel object is at least one of the interface module and the signal processing module;
• a projection module, electrically connected to the signal processing module, configured to receive the projection data and provide an image beam based on the projection data;
• and
• an audio module, electrically connected to the signal processing module, configured to receive the audio data and output sound based on the audio data.
