In virtual reality (VR) education, particularly in creative fields like film production, the role of different environments shaping learning outcomes remains underexplored. This study investigates how three distinct environments-baseline, a dynamic beach setting, and familiar office space-affect students' ability to learn lighting techniques whether team-based offers advantages over individual learning. We conducted 3×2 factorial experiment with 36 participants examine effects these on...
A polarized bifocal switch based on liquid crystals (LC) operated electrically and optically is demonstrated. The mainly consists of two parts: a LC layer as polarization polymeric layers for modulation dependent spatial phase difference which results in positive or negative lensing effect. orientations the molecules are manipulated either switching (ES) mode rewritten (ORW) mode. with an aperture size 10 mm exhibits discrete lens powers (−1.39 Diopter +0.7 Diopter) different states no...
Traditional education is considered incapable of providing prompt feedback, facilitating proactive learning, and giving indiscriminate responses. This has been observed in both in-person classes online courses, especially when students' questions fall outside the instructors' knowledge base or are trivial by instructors. Nowadays, advent large language models (LLMs) transformed acquisition. The LLM-based chatbots enable fast learning through interactive question-answering, which serves as an...
A polarized liquid crystal (LC) lens composed of a LC layers as polarization switch and polymer composites (LCPC lens) is demonstrated with electrically switching (ES) mode optically rewritten (ORW) mode. The power LCPC related to state light modulated by the layer whose orientations are manipulated either or optically. As result, not only switchable, but also rewritable. Each mode, ES ORW exhibits two discrete powers (-1.39 Diopter +0.7 Diopter). aperture size 10 mm. detail optical...
In this paper, a novel pattern steerable antenna array with scanning range of 60° and operating at 2.45 GHz is proposed. The can change the direct current (DC) material by introducing ferroelectric as substrate. DC changed external voltage bias, which realizes continuous feed phase units. consists four parts structure, isolation shifters, elements. They are integrated into two metal layers on both sides floor. Unlike other antennas, maximum radiation from −30° to 30° only controlling...
Aiming at the problem of unclear results and low accuracy ultra-high speed photographic measurement such as transient process glass crack breaking end projectile, a laser source with high power uniform facula was designed, were verified by software simulation field test. First, specific scheme designed according to parameters high-speed camera. High beam generated semiconductor array, compound eye lens used divide superimpose shaping form rectangular facula. Then, mathematical model energy...
