NEW YORK ( TheStreet) -- Tech toys were one of the highlights of Toy Fair 2011 in New York City, which saw lots of classic playthings like board games and boomerangs updated with cutting-edge technology. Mattel ( MAT - Get Report) spiced up its traditional Ken doll with a microphone that plays back up to five seconds of recorded sound, while Hasbro ( HAS - Get Report) introduced new versions of Monopoly and Battleship that contain infared cameras that scan the gameboard to keep track of play. (That's toy company TOSY's newest iteration of Topio below, a ping-pong playing robot.)
Jakks Pacific ( JAKK - Get Report) took a cue from a popular iPhone music app and is releasing an actual microphone that makes you sound like the rapper T-Pain while singing into it. Other top tech trends at this year's Toy Fair include games that incorporate social elements (like those that work with apps), toys focused on science and engineering (like model-building) and playthings that include motion-sensor technology. TheStreet combed the 100,000-plus products on display to bring you some of the best tech-related toys from the event. Read on.
