Research On Techniques And Strategies Of Multi-target Selection For Pen-based Interface

Target selection is a common task in the pen-based interactive interface.However,the traditional multi-target selection technology has higher requirements for the arrangement of the selected targets,and the selection error rate is high,which affects the users interactive experience.Although the traditional technology has an error correction mechanism,it requires both hands to operate at the same time,which is difficult to operate,has a high cognitive load and a long selection time.In order to improve the interactive performance of multi-target selection,a rearrangement mechanism and multi-target selection technology were proposed and designed,and the selection performance of four multi-target selection technologies on three different pen-based interactive interfaces was investigated.Combined with the characteristics of target carrying attributes,a dynamic rearrangement mechanism and a new multi-target selection technology Dynamic Rubik’s Cube are proposed.In order to adapt to the pen-based interactive interface,the Circling and Crossing multi-target selection technology are improved.Through quantitative analysis and qualitative analysis to compare the performance of Circling,Crossing,Dynamic Rubik’s Cube,and Rubber Band,the results showed that Dynamic Rubik’s Cube had certain advantages.In order to verify the rearrangement mechanism and improve the traditional multi-target selection technology,dynamic rearrangement of pen in a single attribute compared with the multi-target selection technology on the interface,the results showed that the rearrangement mechanism effectively improved the target selection technology,especially the performance of the traditional Rubber Band.Rubber Band and Dynamic Rubik’s Cube are suitable for single-attribute rearrangement interface.The multiple main attributes of the target are displayed to verify the influence of the multi-attribute dynamic rearrangement interface on the multi-target selection technology.The results showed that the comprehensive performance of Crossing on the multi-attribute dynamic rearrangement interface through the screening of the target attribute set and the appearance of random targets was the best.Finally,according to the characteristics of different pen-based interactive interfaces and multi-target selection technologies,the interactive strategies,fusion strategies and dynamic rearrangement strategies for pen-based interface multi-target selection technologies are given.At the same time,the application scenarios of multi-target selection technology and dynamic rearrangement mechanism are designed and realized,which provides a reference for the multi-target selection technology of pen-based interface.
