System and method for displaying a product catalog

A non-transitory computer readable medium having stored thereon instructions that, when executed by a processor of a computer, cause the processor to perform a method for displaying a product catalog, the method comprising:

• obtaining a current image and a previous image of a user captured by an image obtaining device from a storage device;
• locating a first face from the current image and a second face from the previous image;
• calculating a first smallest rectangle framing the first face and a second smallest rectangle framing the second face;
• calculating a scalar value between coordinates of the first smallest rectangle and the second smallest rectangle;
• determining a movement direction, a movement speed, and a movement angle of the user's face according to the scalar value;
• and
• rotating a product catalog according to the movement direction, the movement speed, and the movement angle of the user's face.

A computing system for displaying a product catalog, comprising:

• a storage device for storing images captured by an image obtaining device;
• an image obtaining module operable to obtain a current image and a previous image of a user from the storage device;
• a face locating module operable to locate a first face from the current image and a second face from the previous image;
• a calculating module operable to calculate a first smallest rectangle framing the first face and a second smallest rectangle framing the second face;
• the calculating module further operable to calculate a scalar value between coordinates of the first smallest rectangle and the second smallest rectangle;
• an analyzing module operable to obtain a movement direction, a movement speed, and a movement angle of the user's face according to the scalar value;
• and
• a rotating module operable to rotate a product catalog according to the movement direction, the movement speed, and the movement angle of the user's face.
