A smart toy is a toy which effectively has its own intelligence by virtue of on-board electronics. These enable it to learn, behave according to pattern, and alter its actions depending upon environmental stimuli. Typically, it can adjust to the abilities of the player. A modern smart toy has electronics consisting of one or more microprocessors or microcontrollers, volatile and/or non-volatile memory, storage devices, and various forms of input–output devices.[1] It may be networked together with other smart toys or a personal computer in order to enhance its play value or educational features.[2][3] Generally, the smart toy may be controlled by software which is embedded in firmware or else loaded from an input device such as a USB flash drive, Memory Stick or CD-ROM.[4] Smart toys frequently have extensive multimedia capabilities, and these can be utilized to produce a realistic, animated, simulated personality for the toy. Some commercial examples of smart toys are Amazing Amanda, Furby, iDog, and AIBO.[5]
