Abstract: This paper studies the user diet preferences acquisition techonology, and establishes a food category model based on similarity. It designs a system of user diet preferences acquisition and diet recommendation in smart space. The system uses pressure sensors to gain user’s diet data, and captures user diet preferences by dynamic partition of sensor data. It uses the food category model to relize the diet recommendation. Experimental results proves the validity of the system.

Key words: smart space, pressure sensor, dynamic partition, preference acquisition, diet recommendation
