Human-centered 3D home applications via low-cost RGBD cameras

In this chapter, we will introduce three human-centered home 3D applications realized by virtue of low-cost RGBD cameras. The first application is personalized avatar for user via multiple Kinects, which can reconstruct a real human and provide personalized avatars for everyday users and enhance interactive experience in game and virtual reality environments. The second application automatically evaluates energy consumption of users in gaming scenarios by a model with tracked skeleton, which may help users to know their exercise effects and even diet or reduce their weights. The final application presents a real-time system that automatically classifies the human action acquired by consumer-priced RGBD sensor.
