Apparatus and method for interaction between content and olfactory recognition device

An olfactory recognition system for recognizing an odor provided by a user or a spontaneously generated odor and causing a reaction to the odor in a realistic content, comprising:

• an olfactory recognition device including a plurality of gas sensors, the olfactory recognition device recognizing the odor and generating data as a result of the recognition,
• wherein the olfactory recognition device comprises a device module, a device information service stack, a device information datasheet, and a device communication module, and
• the device module comprises a gas sensor for olfactory recognition, drives the gas sensor, and controls an overall function of the device module including a communication function, the device information service stack provides functions and service functions for information exchange between the olfactory recognition device and the content device, and the device information datasheet includes electrical characteristics and sensor characteristics of the gas sensor for olfactory recognition;
• a content device for receiving the recognition result data and then producing a reaction to the recognition result data, wherein the reaction includes a modification of the realistic content in response to the recognition result data, and where realistic content includes visual content and olfactory content;
• and
• an interface for bidirectionally performing transmission and reception of data including the recognition result data between the olfactory recognition device and the content device,
• wherein a method of allowing the olfactory recognition device to interact with the content device is performed by one or more of an automatic mode, a manual mode, and a reference mode, and
• wherein when the realistic content facilitates a change in a recognized odor information transfer mode, if new mode information is transmitted to a content information service stack of the content device, and the content information service stack transmits a mode change request signal to a device information service stack of the olfactory recognition device, the device information service stack of the olfactory recognition device provides an approval signal to the content information service stack, and the content information service stack transmits mode information desired to be changed to the device information service stack of the olfactory recognition device.
