发布时间：2018-10-10 11:25
【摘要】：触控交互、笔式交互和空间手势交互因其交互自然直观的性能特点,被广泛应用于各类交互设计当中。触控交互不需要额外的交互设备,相比于鼠标键盘等交互方式更加便捷,然而操作过程中的遮挡和“肥手指”问题影响了用户的操作。笔式交互基于传统纸笔交互,用户可以迅速掌握其操作方式。笔的操作精确度相对较高,但其只使用二维坐标信息,输入带宽偏低。空间手势利用人体关节的自然属性的变化表达丰富的语义信息,但长时间的空间手势操作产生的疲劳感将对输入性能产生影响。为了在保证交互操作精确度的基础上,充分利用3种交互技术的优势,提升输入效率,本研究根据实际绘图场景设计混合输入技术并对其展开评估。以实证研究的方式对触控、笔和空间手势的输入性能展开了对比。研究结果表明,笔更适合进行精确操作,且受目标尺寸变化的影响较小;触控和空间手势更适合完成精确度要求相对较低的操作,与笔操作相比,触控的操作速度较快;触控和空间手势因摩擦力和易疲劳的原因不适合进行长时间操作。以性能对比研究结果和定性分析结果为基础,结合实际绘图场景中操作任务的特点,在单因素控制条件和双因素控制条件下设计双通道和三通道混合输入技术:双通道顺序输入下的触控按钮+笔输入技术(DS-TB+P)、触控点击+笔输入技术(DS-TC+P)、触控滑动+笔输入技术(DS-TS+P),双通道交叠输入下的空间静态手势+笔输入技术(DO-MSG+P),双通道并行输入下的触控+笔输入技术(DP-T+P),双通道二维空间划分下的触控点击+笔输入技术(D2D-TC+P),双通道三维空间划分下的空间静态手势+笔输入技术(D3D-MSG+P),三通道功能粒度控制输入技术(TG-MSG-TC+P)和三通道功能离散控制输入技术(TD-TC+MSG-P)。分别通过单因素控制条件和双因素控制条件下的混合输入实验,对几种技术的输入性能展开评估。研究结果表明,在单因素控制条件下DS-TB+P和DS-TC+P的总体表现最佳,而DS-MDG+P的总体性能和主观评价最低。在双因素控制条件下的混合输入环境下,D2D-TC+P的总体表现最佳,而D3D-MSG+P在操作性能和总体评价上均表现最不理想。最后综合实验结果和分析,提出混合输入技术的设计建议并设计混合输入技术的应用场景。
[Abstract]:Tactile interaction, pen interaction and spatial gesture interaction are widely used in all kinds of interaction design because of their natural and intuitive performance. Tactile interaction does not require additional interactive devices, so it is more convenient than other interactive methods such as mouse and keyboard. However, the occlusion and "fat fingers" problems in the operation process affect the user's operation. Pen-based interaction is based on traditional paper-pen interaction, and users can quickly master its operation. The accuracy of the pen is relatively high, but it only uses two-dimensional coordinate information, and the input bandwidth is low. Spatial gestures express abundant semantic information by changing the natural attributes of human joints, but the fatigue produced by spatial gestures for a long time will affect the input performance. In order to make full use of the advantages of the three interactive technologies and improve the input efficiency on the basis of ensuring the accuracy of interactive operation, the mixed input technology is designed and evaluated according to the actual drawing scene. In this paper, the input performance of touch, pen and spatial gesture is compared by empirical study. The results show that the pen is more suitable for precise operation and less affected by the change of target size, touch control and spatial gesture are more suitable for the operation with lower precision, and the tactile operation speed is faster than that of pen operation. Touch and space gestures are not suitable for long time operation due to friction and fatigue. Based on the results of performance comparison and qualitative analysis, combined with the characteristics of operational tasks in the actual drawing scene, The design of two-channel and three-channel hybrid input technology under the condition of single factor control and double factor control: touch button pen input technique (DS-TB P), tactile click pen input technique) (DS-TC P), touch sliding technique) under two-channel sequential input Pen input technique (DS-TS P), double channel overlapping input) static gesture pen input technique (DO-MSG P), dual channel parallel input pen input technique) (DP-T P), dual channel two dimensional space division of tactile click pen input technique Spatial static gesture pen input technique (D3D-MSG P), three-channel functional granularity control input technique (TG-MSG-TC P) and three-channel discrete control input technique (TD-TC MSG-P) under D2D-TC P), dual-channel three-dimensional space division. The input performance of several techniques is evaluated by mixed input experiments under single factor control condition and double factor control condition respectively. The results show that the overall performance of DS-TB P and DS-TC P is the best, while the overall performance and subjective evaluation of DS-MDG P are the lowest. The overall performance of D2D-TC P is the best under the condition of mixed input under the condition of two-factor control, while the performance of D3D-MSG P is the most unsatisfactory in operation performance and overall evaluation. Finally, based on the experimental results and analysis, the design suggestions of hybrid input technology and the application scenario of hybrid input technology are proposed.
