Patent number: 10777019Abstract: An object of this disclosure is to provide a technology for providing 3D reading scenarios. The technology includes: acquiring, in a VR reading mode, corresponding 3D scenario information based on a literature work currently read by a user; and establishing, in cooperation with VR glasses, a 3D reading scenario for the literature work based on the 3D scenario information. Compared with the existing technologies, this disclosure can acquire the corresponding 3D scenario information based on the literature work, and establish the 3D reading scenario for the literature work using the 3D scenario information. Moreover, this disclosure in cooperation with VR glasses further realizes an immersed reading experience by reading literature works in a 3D scenario. This not only improves the monotone disadvantage of the traditional reading scenario, but also brings users into an immersed reading environment in the reading process, and greatly enhances the users' reading experience.Type: GrantFiled: September 18, 2018Date of Patent: September 15, 2020Assignee: Baidu Online Network Technology (Beijing) Co., Ltd.Inventors: Miaomiao Feng, Wen Hou, Bingbing Li, Qinglong Li
