Comment on "Outage Probability Analysis of a MIMO Relay Channel with Orthogonal Space-Time Block Codes"

We point out that a simpler expression could be derived for the outage probability considered by Chalise and Vandendorpe (2008). As a result, the computation of confluent hypergeometric function of two variables is not needed and the required computational effort is significantly reduced.

Frames of Reference in Mobile Augmented Reality Displays.

In 3 experiments, the authors investigated spatial updating in augmented reality environments. Participants learned locations of virtual objects on the physical floor. They were turned to appropriate facing directions while blindfolded before making pointing judgments (e.g., "Imagine you are facing X. Point to Y"). Experiments manipulated the angular difference between the learning heading and the imagined heading and between the actual heading and the imagined heading. The effect of actual-imagined on pointing latency was observed for naive users but not for users with brief training or instructions concerning the fact that objects can move with body movements. The results indicated that naive users used an environment-stabilized reference frame to access information arrays, but with experience and instruction the nature of the representation changed from an environment stabilized to a body stabilized reference frame.

一种基于像素自适应仲裁的OSD分层混合结构设计

数据混合是OSD分层显示的关键技术之一.本文基于OSD的分层结构及数据组织结构特点,提出一种OSD分层显示的单混合结构,该结构采用基于像素自适应仲裁的策略,按照层优先级次序,对多个OSD图层信号实时地切换显示.FPGA验证结果表明,该结构在满足OSD分层混合显示、实现菜单选择鼠标控制等高级人机对话功能的前提下,其硬件资源开销比多混合结构节省约33%以上,且具有良好的层次可扩展性和操作灵活性.
