| In daily life,the interface interaction tasks in tablet computers can be divided into two types of tasks in which the position of the operating object changes or the position remains unchanged during the operation process.In interactive tasks where the location of the operating object changes,the direct-copy-paste method for copying and pasting targets has complex operating instructions.Due to the lack of shortcut key coordination on tablets,the operation process is cumbersome.When operating multiple targets,it is impossible to complete the interactive task through one operation,which can easily lead to user fatigue.The target zoom task only changes the size of the operand itself,and its position does not move.When completing a zoom task,users need to perform multiple pinching and unfolding actions or drag the screen for a long distance,resulting in discomfort caused by finger friction.In a grip state,such operations can lead to poor device stability and heavy psychological burden on users.This topic first proposes control-to-copy-paste method and multi-touch-to-copy-paste method based on the copy and paste task of changing the position of the operating object.The performance is compared with the direct-copy-paste method,and the interactive performance of the new technique is discussed from both qualitative and quantitative analysis.The results show that for the target copy and paste technique,the control-to-copy-paste method has the best performance,has been praised by users.The comprehensive performance of the control-to-copy-paste method and the multitouch-tocopy-paste method have been improved by 94% and 93%,respectively;The operating speed has been increased by 400% and 274% respectively;The false triggering rate decreased by 54.72% and 42.48% respectively;The accuracy rate increased by 4.62% and5.6% respectively.Two new techniques have improved interaction efficiency and finger input capabilities.Secondly,based on the classification of target scaling tasks with unchanged operating object positions,a control-to-zoom method is proposed for equal scale scaling with unchanged aspect ratio during scaling,and its overall performance is doubled compared to the common kneading scaling method;Operating speed increased by 59.1%;The distance deviation has been reduced by 10.9%.A static-point-to-zoom method is proposed for non-equal scaling with varying aspect ratios during scaling.Its overall performance is improved by 50% compared to the common drag-to-zoom method,and the operating speed is improved by 110.5%.The two zoom techniques have received high user ratings,greatly improving interaction efficiency,reducing the psychological burden of users completing the zoom task of the tablet while holding it,and improving the user’s interactive experience.Finally,according to the technical characteristics of target copy and paste and target zoom tasks,we propose strategies for using new interactive techniques for both tasks.Considering practical applications,design application scenarios for different interaction techniques to provide new design ideas and theoretical references for tablet computer interaction technique design. |
