Summary: This study explores users' pointing performance on large virtual curved displays and finds that the less curved the display, the higher the users' performance. Additionally, display curvature also affects the error rate. The study also shows that curved displays perform well or similarly to flat displays in terms of performance.

Summary: The study compared three mobile phone pointing techniques in Spatial Augmented Reality (SAR): raycast, viewport, and direct, with raycast being the fastest for non-occluded targets, direct being the most accurate, and viewport falling in between. A new Fitts' model combining two spatial configurations was formulated and evaluated using experiment data, showing better predictive performance than previous models in SAR pointing tasks.

Summary: Visual analysis of dynamic networks can be challenging, especially when comparing disjoint timeslices. Interactive timeslicing shows benefits for comparing distant time points, but less effectiveness for analyzing contiguous time intervals. These findings highlight the importance of finding the most suitable interactive visualization method for different tasks related to dynamic networks.

Summary: Inorganic-based micro light-emitting diodes (microLEDs) have unique properties and demands due to their small size, making it challenging to integrate millions of microLED chips accurately and cost-effectively. Recent technological advances, such as laser lift-off technique and contact micro-transfer printing, have overcome these challenges and presented new solutions for mass transfer in the assembly of ultra-large displays and virtual reality glasses.

Summary: This paper conducted a virtual hand clicking experiment in virtual reality (VR) to test the performance of virtual hand buttons. The experiment results suggested optimal design requirements for button width and spacing under specific distances. The information throughput (TP) of virtual hand clicking in virtual environments was found to be between that of a mouse and a handheld touch screen. These findings provide valuable guidance for the interface design of virtual hand clicking interactions in virtual environments.

Summary: In this paper, we propose a novel space-efficient technique for redirection in VR, called RedirectedDoors, which focuses on the door-opening behavior. The technique manipulates the user's walking direction by rotating the entire virtual environment at a certain angular ratio of the door being opened. The results of our user study show that our technique achieves a higher space efficiency of redirection and providing haptic feedback improves the realism and comfort of the user experience, although it increases the noticeability of redirection.
