The invention discloses a holographic touch interactive exhibition 
system with multisource input and intelligent information optimizing functions. The 
system senses surrounding environment information by the aid of a plurality of sensors, a 
smoke sensor is started to monitor fire without audiences, faces in videos are recognized when the audiences are present, proper 
broadcasting information is recommended, and the identity sense of customers is enhanced. The exhibition 
system introduces an interactive mode, and the audiences can realize man-
machine interaction by the aid of a holographic touch screen to acquire information that the audiences want to know. Besides, by the aid of an intelligent 
information mining algorithm and features extracted by a color co-occurrence matrix, finding of a 
facial expression recognition area of interest and 
feature extraction are combined into one step, the faces are clustered by the aid of an 
affinity propagation clustering 
algorithm, and the 
broadcasting information is changed according to emotion. By the aid of the exhibition system, the information can be effectively pushed according to ages and genders of the audiences in a complicated background environment, sufficient exhibition can be realized, the audiences can be guided to more comprehensively know the information, and the identity sense of the audiences is enhanced.
