Design of Learning Media in Mixed Reality for Lao Education

To improve and develop education systems,the communication between instructors and learners in a class during the learning process is of utmost importance.Currently the presentations of 3D models using mixed reality(MR)technology can be used to avoid misinterpretations of oral and 2D model presentations.As an independent concept and MR applications,MR combines the excellent of each virtual reality(VR)and augmented reality(AR).This work aims to present the descriptions of MR systems,which include its devices,applications,and literature reviews and proposes computer vision tracking using the AR Toolkit Tracking Library.The focus of this work will be on creating 3D models and implementing in Unity 3D using the Vuforia SDK platform to develop VR and AR applications for architectural presentations.

青光眼视觉康复研究现状与展望

青光眼在当今世界不可逆性致视觉损伤的眼病中位居前列,其所引起的视觉障碍严重影响患者的日常生活及社会心理功能,导致患者生活质量大幅度下降。通过利用患者残余视功能进行视觉损伤康复可有效改善患者生活质量,但目前社会各界对青光眼所致视觉障碍以及视功能康复的重视程度尚显不足。本文总结国内外相关领域的研究进展,从青光眼视觉损伤的流行病学现状入手,揭示青光眼视觉损伤问题的普遍性和严重性,并围绕患者视觉质量的改变特点、患者的康复需求与服务的供给现状、新型扩大视野的辅助设备和最新行之有效的康复干预方法等核心问题进行综述,以期为青光眼视觉康复研究提供一定的启发和思路。
