Melo Legarda et al.: Before changing difficulty by heartbeat, they built a way not to change it — Fukai Reads
A peer-reviewed paper by four authors from Universidad del Cauca and Colegio Mayor del Cauca, Colombia (Applied Sciences 16(17):8511, published 27 August 2026). They built a mechanism that adjusts game difficulty from a chest-strap heart sensor and logged eight sessions totalling 6 hours 48 minutes. Mean end-to-end latency was 2.06 s. The striking number: against 191 committed state transitions there were 83 flips the automaton withheld — nearly a third of the change-or-hold decisions land on “do not change”. No subjective data was collected, and the authors never claim the game became more enjoyable.
Wu et al.: Rebuilding a Case Report Into a Chain of Decisions — Fukai Reads
A medical-education gamification paper by Qian Wu and colleagues (CUHK and others). MedGame is a dual-engine framework that converts static case reports into a three-level Act / Scene / Decision Node script and then into a dependency graph of multimodal generation tasks. Fine-tuning on a 5,000-case benchmark lifts structural validity from 79.4% to 99.1%, while medical accuracy plateaus around 7 out of 10.
Jeong 等：同一问题，换一种答题方式，难度也会不同——Fukai 解读
由 Harim Jeong 等人撰写的关于认知负荷与交互设计的论文（发表于 JMIR Serious Games，已通过同行评审）。在平板电脑上的斯特鲁普任务中，保持刺激不变，仅将答题方式从文字标签改为色块，127名6至12岁儿童的正确率从0.86提升至0.91，反应时间缩短了85.4毫秒。前额叶脑指标未出现显著差异。
Wermann et al.: How In-Game AI 'Words' vs 'Demonstration' Change Learning and Cognitive Load — Fukai Reads
A pre-registered experiment by LMU Munich and colleagues comparing 'verbal' and 'demonstration' support from an in-game AI NPC. Splitting 152 people into three groups in Qookies, a quantum-technology learning game, they found no difference in learning gains between conditions, but the verbal-plus-visual group reported significantly lower intrinsic cognitive load than the verbal-only group (d=0.60).
Liu et al.: AI Assistance Erodes Persistence — A Warning for Hint Design — Fukai Reads
A paper by Grace Liu and colleagues on how AI assistance affects independent problem-solving and persistence. Across RCTs with 1,222 participants, AI raised in-session performance but, once removed, left people solving less and giving up more. Those who got direct answers declined most while hint-users did not, a result that speaks directly to game hint design.
McConnell & Zhao：用遗传算法实时生成「恰到好处」难度谜题 — Fukai 的读书笔记
McConnell 与 Zhao 关于使用遗传算法进行自适应谜题生成的论文。将类似 Cosmic Express 的路径谜题，根据记录玩家解题方式的玩家模型，以每题约7秒的速度实时生成，并在18人实验中证明「仅依赖时间指标」的版本在体感难度与进度感方面逊色于其他版本。
