【摘要】：觸控交互、筆式交互和空間手勢交互因其交互自然直觀的性能特點,被廣泛應用于各類交互設計當中。觸控交互不需要額外的交互設備,相比于鼠標鍵盤等交互方式更加便捷,然而操作過程中的遮擋和“肥手指”問題影響了用戶的操作。筆式交互基于傳統(tǒng)紙筆交互,用戶可以迅速掌握其操作方式。筆的操作精確度相對較高,但其只使用二維坐標信息,輸入帶寬偏低�？臻g手勢利用人體關節(jié)的自然屬性的變化表達豐富的語義信息,但長時間的空間手勢操作產(chǎn)生的疲勞感將對輸入性能產(chǎn)生影響。為了在保證交互操作精確度的基礎上,充分利用3種交互技術的優(yōu)勢,提升輸入效率,本研究根據(jù)實際繪圖場景設計混合輸入技術并對其展開評估。以實證研究的方式對觸控、筆和空間手勢的輸入性能展開了對比。研究結果表明,筆更適合進行精確操作,且受目標尺寸變化的影響較小;觸控和空間手勢更適合完成精確度要求相對較低的操作,與筆操作相比,觸控的操作速度較快;觸控和空間手勢因摩擦力和易疲勞的原因不適合進行長時間操作。以性能對比研究結果和定性分析結果為基礎,結合實際繪圖場景中操作任務的特點,在單因素控制條件和雙因素控制條件下設計雙通道和三通道混合輸入技術:雙通道順序輸入下的觸控按鈕+筆輸入技術(DS-TB+P)、觸控點擊+筆輸入技術(DS-TC+P)、觸控滑動+筆輸入技術(DS-TS+P),雙通道交疊輸入下的空間靜態(tài)手勢+筆輸入技術(DO-MSG+P),雙通道并行輸入下的觸控+筆輸入技術(DP-T+P),雙通道二維空間劃分下的觸控點擊+筆輸入技術(D2D-TC+P),雙通道三維空間劃分下的空間靜態(tài)手勢+筆輸入技術(D3D-MSG+P),三通道功能粒度控制輸入技術(TG-MSG-TC+P)和三通道功能離散控制輸入技術(TD-TC+MSG-P)。分別通過單因素控制條件和雙因素控制條件下的混合輸入實驗,對幾種技術的輸入性能展開評估。研究結果表明,在單因素控制條件下DS-TB+P和DS-TC+P的總體表現(xiàn)最佳,而DS-MDG+P的總體性能和主觀評價最低。在雙因素控制條件下的混合輸入環(huán)境下,D2D-TC+P的總體表現(xiàn)最佳,而D3D-MSG+P在操作性能和總體評價上均表現(xiàn)最不理想。最后綜合實驗結果和分析,提出混合輸入技術的設計建議并設計混合輸入技術的應用場景。
[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.
