情感计算中的实验设计和情感度量方法研究
摘 要
情感计算的目标是赋予计算机感知、理解和表达情感的能力,而情感数据的获取和情感真值的度量是情感计算的研究基础。为了更好地进行情感度量的研究,以FIFA足球电子游戏为场景,进行了精心设计的实验,即首先通过游戏场景诱发游戏者自然的情绪反应;接着提出了基于情绪脚本的情感编码方法,并结合范畴法和维度法对情感数据进行了自评和他评;最后对观察者间的一致性进行了统计分析。实验结果表明,该方法能够获得有效一致的情感度量结果。

ZHANG Yinghui, LIN Xueyin(Department of Computer Science and Technology, Tsinghua University, Beijing 100084) Abstract
The purpose of affective computing is to enable computers to perceive, understand and express emotionsAffect data acquisition and affect measure are essential to the research of affective computingTo explore the problem of affect coding, experiments were elaborately performed in the scenario of FIFA football electronic gameFirstly natural affect of game players were elicited in the game environmentThen a scheme of affect coding based on emotion prototypes was proposed, and both categorical emotions and levels within the affective space were assessed by game players as well as third-party observersFinally an analysis was performed on the inter-observer agreementThe experiment data showed that valid and consistent affect coding results can be attained with the proposed method
