The present invention provides a smart tool for real-time measurement of a changing environment and real-time display of such information to the user, thereby supporting the user for example in surgery. Visual information in the vicinity of the tool tip is displayed to the user of the tool as haptic information. The smart tool comprises a tool (surgical knife), a light-receiving element for receiving the light reflected by an object in the vicinity of the tool tip, a decision portion for deciding the brightness and/or color of the object in the vicinity of the tool tip based on the output from said light-receiving element, a repulsive force calculation portion for calculating the repulsive force to be applied to said tool based on the output from said decision portion, a motor driving circuit for applying repulsive force to said tool based on the output from the repulsive force calculation portion, a motor, and a wire.
