Educational system, method, computer program product and kit of parts

摘要

An educational system comprises a set of science experimental items and a computer system including a detector and a display. The computer system is configured to display educational media content on the display relating to the experimental set in response to the detector detecting an item in the science experimental set and the computer identifying the media content to be displayed based on the detection of the item. The detector may detect a code applied to the item or the shape of the item using image recognition. The educational system may be provided in instalments as part of a mail-order system which may include reminders to perform the next experiment. Also envisaged is a defocus code system including a printed code and a computer system including a camera. The printed code contains less than 20 bytes of information and the computer system can read the code when the camera is not focused on the code. The code may be a coloured dot matrix code including an orientation symbol and an error checking code.
