A sensor, and an information display method for sensor and a system thereof are provided. First, an original image with an anthropomorphic object is provided. Next, plenty of sense information is received one by one. The sensor is used to detect physiological information or motion information or environmental information of a user for generating the sense information. Afterwards, the sense information is gathered statistics to obtain a sense record. Then, a status, which is after a period time, of the anthropomorphic object is forecasted according to the sense record. Next, the original image is changed to a forecasting image according to the status. Finally, the forecasting image is display. Accordingly, the user can know daily lives any time by the change of the image.一種感測器及其資訊顯示方法與系統。首先,提供具有人形物體的原始影像。接著,依序接收多個感測資訊,這些感測資訊是利用感測器所偵測一使用者的生理資訊、運動資訊或是環境資訊所產生。之後,統計這些感測資訊,以獲得感測記錄。然後,依據感測記錄,預測當經過一段時間之後人形物體的狀態。再依據上述狀態,變更原始影像為預測影像。最後,顯示預測影像。據此,藉由影像的改變,使用者可隨時瞭解其日常生活作息。S205~S230‧‧‧本發明第一實施例之感測器的資訊顯示方法各步驟
