A miniature rotor craft controlled through a head-mounted display and Lego blocks manipulated with a PlayStation controller: These were just a couple of examples of new ideas and creativity on display last week at a two-day open house held by Sony Computer Science Laboratories Inc.

About 30 scientists and researchers working for the lab in Tokyo's Gotanda district showcased their projects at the open house, which is usually held once every two years.

One eye-catching technology was the Flying Head, a miniature camera-equipped helicopter that sends video to a head-mounted display, which is used to fly it.
