Gizmodo Japan: Auto door

Gizmodo Japan: Auto door: " Cleanliness, efficiency, compactness, cool-factor for a variety of reasons, automatic doors have become a standard feature of Japanese shops. While the typical sliding star-trek style design has proven itself, the tanaka auto door aims to improve upon a good concept. This new design entails strips equipped with infrared sensors that open to the approximate shape of the person or object passing through, minimizing entry of dust, pollen, and bugs while keeping precious air-conditioning in."
