Fanctionality and Cognition of Agent Icons in Virtual Space

研究了三维虚拟空间中智能体图标的功能与认知之间的关系。具体性、功能性、立体性和复杂性是四个设计要素。根据这些设计元素的设计概念绘制了Agent图标，并对这些图标的可理解性进行了检验。并采用新的图标图片心理距离测量方法进行了评价实验。根据实验结果，给出了与各设计要素相对应的设计准则.此外，设计了四个元素之间有联系的图标，并对它们的可理解性做了进一步的实验。在此基础上，提出了高认知图标的设计原则。其次，对三维智能体图标进行了操作实验。受试者被要求戴上液晶快门红色眼镜。屏幕上出现的球形图标。受试者操作三维a ...更多信息 l鼠标具有6个自由度来指向目标图标。结果表明，光标到图标的距离与操作时间呈正相关，图标的大小影响操作时间。这些发现也表现在二维空间中的点运算特征中。在图标目标周围经常看到微小的点修改。然而，Fitts定律在3D鼠标的总体操作上得到了结论。第三，研究了虚拟空间中图标位置的估计方法。距离是从光标位置到目标图标的距离，角度α被定义为从光标位置到目标位置的向量的角度。定义了基于这些参数的评价函数。改变这些参数的系数，并进行了实验。在操作时间和正确命中率方面，提出的估计方法优于顺序法，具有上级的优点。但是，它不能显示的角度和距离的参数，对估计的贡献很大。未来的工作是检查的估计方法为中心的操作模型的主题。少

Relation between function and cognition of agent icons in three-dimensional virtual space was examined. Four design elements were concreatness, functionality, dimensionality and complicatedness. Agent icons were drawn under the design concepts about these design elements, and comprehensibility of these icons were examined. Moreover the evaluation experiment by the new measure of the mental distance between the icon pictures was carried out. Results from these experients a design guideline corresponding to each design element were shown. Furthermore, the icon that have relations among the four elements was designed, and an experiment was further done about their comprehensibility. Then, the design guideline of the high cognitive icons was proposed newly. Secondly, the experiment about the operation of the three-dimensional agent icons was done. Subjects were made to attach liquid crystal shutter red glasses. The globular icon presented on the screen. Subjects operated a three-dimensiona … More l mouse with a degree of 6 freedom to point target icons. Results showed that the distance from cursor to the icon and operating time had positive relationship, and the size of icons effected to the operating time. These findings were also shown in a point operation character in the two-dimensional space. Minute point modification was seen frequently around the icon targets. However, the Fitts' law was concluded on the total operation of the 3D mouse. Thirdly, The estimation method of an icon position in the virtual space was examined. A distanced was from the cursor position to the target icons, and an agle a was defined as angle of the vector from a cursor position to a target position. An evaluation function by these parameter was defined. The coefficient of those parameters was changed, and an experiment was carried out. Proposed estimation method was superior to the ordinal method in operating time and correct hitting rate. However, it couldn't show which parameter of the angle and the distance contributed to the estimation strongly. Future work is to examine the estimation method centered in the operation model of the subject. Less
