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.
