Methods and systems for generating virtual reality environments from electronic documents

摘要

Generating a virtual reality environment from an electronic document by mapping image and text content extracted from the electronic document to a virtual reality module. First an electronic document is analysed to identify the document elements that occur within the electronic document 210. The document elements are parsed to identify candidate images that have minimum image characteristics suitable for virtual reality 220, 230. One or more of the candidate images are inserted into the virtual reality module 240. Text elements related to the candidate images may also be inserted into the virtual reality module 250, 260. Preferably, upon execution of the virtual reality module by a virtual reality viewing device, the text and image elements from the electronic document are presented in a virtual reality environment to the viewer for non-linear exploration and reading. Preferably, a plurality of N-gram sequences of text indicating a probability of the text occurring within a portion of the electronic document are generated. At least one of these N-gram sequences is then selected so as to carry out an online search to identify additional images which can be inserted into the virtual reality module at positions relative to the originals candidate image.
