动作环境下液晶显示荧幕对阅读绩效与视觉疲劳之影响

今日交通工具中广泛使用液晶显示萤幕,荧幕也随着各式各样的振动对人产生影响.尤其人们眼睛在阅读精确的文章时,振动所造成不适,影响就变得更剧烈,因此容易造成阅读绩效不佳与视觉不适.本研究想要探讨液晶萤幕在不同振动情形(振动频率、振动振幅与不同振动方向)对数字大小、数字多寡与数字排列之影响.阅读绩效与视觉疲劳的量测为反应时间、正确率、闪光融合阈值、视力变化与主观评量,由实验得到频率对反应时间、正确率与视觉疲劳有显著的影响.因此荧幕硬件与软件之设计必须考虑到振动的影响.     

The Characters of a Sylow p-Subgroup of the Group G2(pn), p≠2, 3

 We compute the irreducible complex characters of a Sylow p-subgroup of the Chevalley group G ₂(q), q=p ⁿ , p≠2, 3 and show that the non linear irreducible characters are induced from linear characters of subgroups of order q ⁵ and q ⁴. Received April 6, 1995

优先股的特征和我国的制度设计

优先股是相对普通股而言的金融创新产品,融合了股权与债权两者的优点,投资人既能获取低风险收益,在利益遭遇侵害时又不失产权人应有的权利诉求。因此,在我国资本市场供给失衡的背景下推行优先股制度具有重要的现实意义。     

Perception of psychopathy and the Uncanny Valley in virtual characters

Virtual characters with a realistic, human-like appearance are increasingly being used in video games and animation. However, increased realism does not necessarily imply increased acceptance and factors such as aberrant facial expression may evoke the Uncanny Valley phenomenon. In humans, personality traits such as anger, callousness, coldness, dominance, being unconcerned, and untrustworthiness are associated with psychopathy; a visual facial marker of this condition being a lack of visible response in the eye region to emotive situations. As such, the present study investigated if inadequate upper facial animation in human-like virtual characters evoked the uncanny due to a perception of psychopathic traits within a character. The results revealed that virtual characters that showed a lack of a startle response to a scream sound were regarded as most uncanny and perceptions of personality traits associated with psychopathy were a strong predictor of reported uncanniness but, that other negative personality traits not associated with psychopathy were not. The study presents possible psychological drivers of uncanniness to inform designers why a lack of detail in a character’s upper face when portraying a startle response may evoke perception of specific negative personality traits in a character, to help control the uncanny in character design.
