功能是产品的本质属性，然而随着机床设计的高科技化、数码化，其功能日趋复杂，操作界面让人眼花缭乱，即使是CRT操作屏幕也让人一下子难以明白。一旦机器出现故障，打开机盖，裸露出复杂构件，没有丝毫视觉上的暗示，往往无从着手，而操作手册更是充斥着大量技术名词，操作因此变成一项复杂而困惑的事情。功能示意性语意的表达要求设计师找到一种能准确传达情感的语意符号，通过外在视觉使内部机构功能更明确，使人机界面单纯易理解。这一过程也就是设计师编码而操作使用者解码的过程，设计师的语意传达必须建立在使用者操作经验的基础上，把握操作人员的生理特征和行为特性，使设计起到准确传达功能的作用。功能标识在机床产品显示和操作区域的细部设计中犹为突出。如按钮表面做成手指负形；操纵杆外形做成手掌负形；设置纹理增加把持摩擦力；通过纹理方向暗示操作运动方向等，增加人机互动，人机交流，以形体本身说明其操作方法。
參考答案:Product function is the essential attribute, however, with the high-tech machine tool design, digital, and its function is becoming increasingly complex. Operator Interface dazzling, even CRT screen operation is also difficult to understand immediately. Once a mechanical fault plane opened the lid open and more complex components without the slightest hint of visual often begin. Operating Manual is flooded with a lot of technical terms, the operation has become more complex and perplexing things. Indicative of the functional meaning to express their demands to find a designer can accurately convey emotional meaning symbols, to the internal structure of the external visual function more clearly so that people Machine Interface simple easy to understand. This process is a designer of the coding and decoding process user operation. Designers must convey the meaning users operating on the basis of experience. grasp the physical characteristics and behavior of the operator, played accurately convey the design function. Function marking machine products show in detail the design and operation of the region are still outstanding. If button-shaped surface caused negative fingers; The stick-shaped configuration caused palm negative; Texture increase friction dominated installed; texture implies that the direction of movement through the operation, increase human interaction and human exchanges, and its physical operation itself.
