Most children love to scribble sketch and draw on paper but imagine if they could record their own voice or other sound effects to the same drawing.
Hayes Raffle and his team at MIT have created a tool called Jabberstamp that allows children to record sound and voices to their drawings made on normal paper using pencils and crayons.
Children have to press a rubber stamp (see video) onto the page to record sounds into their drawings. The audio will playback when people touch the marks of the stamp with a small trumpet.
Internally, Jabberstamp is an electronic tablet with sensor while the rubber-stamp is fitted with a microphone to record sound. The sensors in the tablet keep track of the position of the stamp and encode the audio at that location. When the tablet senses the trumpet over an audio position, it plays the sound back.
Microsoft OneNote also allows you to record audio anywhere on the screen but that's probably too complex for young children. The day when JabberStamp is released as a standalone software, the TabletPC with a headset microphone would become the favorite toy of many children.
