We have developed several applications for the mobile users. I will introduce some of them for you. ARDetail shows the details information of products. At the same time, the user can see actual appearance and size under real environment. SLAM and various kinds of detections are integrated intelligently to make the tracking fast and stably.

After the customer shoots at the object, such as electric appliance, the application will pop up the 3D model of this appliance cover the real one. The customer can press the button of the model, which led the application to give useful information to the customer. It helps the customer to understand the product correctly and completely.
