That's according to a March 26 post on the Microsoft "Kinect for Windows" blog from Craig Eisler, the general manager of the product.
Eisler said the 1.5 release will add a new app called Kinect Studio "that will allow developers to record, playback and debug clips of users engaging with their applications." The 1.5 release also will feature "seated," or "10-joint" skeletal tracking, which will add the ability to track the head, neck and arms of either a seated or standing user that will work in both default and near mode.
The 1.5 update will add four new languages for speech recognition – French, Spanish, Italian, and Japanese -- as well as language packs to enable speech recognition for languages spoken differently in different regions (like English/British English).
Eisler said Kinect for Windows will be launching in 19 more countries in May and June, including Hong Kong, South Korea, Taiwan, Austria, Belgium, Brazil, Denmark, Finland, India, the Netherlands, Norway, Portugal, Russia, Saudi Arabia, Singapore, South Africa, Sweden, Switzerland and the United Arab Emirates.
