Haptic interaction technology is widely used in many areas,such as medical,education,shopping,entertainment and military,which have greatly enriched the information user obtained through the electronic equipment.People can operate the device more efficiently and accurately through touch interactive technologies applied to the mobile terminal,which brings a great deal of convenience to the user's study and life.The research on the interaction accuracy and efficiency of mobile terminals is a research hotspot in the field of intelligent human-computer interaction,which has important guiding significance for improving the usability of interactive interfaces and designing commercial interactive interfaces.The introduction of tactile feedback can increase the effective interaction between the operator and the virtual world,which directly affect the interactive performance of human-computer interaction.The research on the interaction accuracy and efficiency with tactile feedback will be different from the traditional touch interaction mode.The influence of tactile feedback on human-computer interaction performance needs to be further studied.Based on the application of electrovibration and vibration tactile feedback technology of mobile terminal,the gesture interaction with naked fingers as the research object,studying the effect on the performance of human-computer interaction with electrovibration and mechanical vibration tactile feedback,mainly including qualitative effect on the properties of interaction,the applicability of the theoretical model and interactive accuracy-efficiency model characterization.Contributions and innovative work are as follows:First,this paper proposes a Steering Law interaction model under electrovibration tactile feedback technology,which can be used to predict the completion time of interactive tasks based on trajectory navigation interactive tasks of touch screen under different electrovibration conditions.The influence of electrovibration tactile feedback on efficiency and accuracy of interaction operation was qualitatively and quantitatively analyzed through naked finger interaction experiment on touch screen,and the applicability and application conditions of the interaction model were tested through descriptive and predictable analysis.The results show that high intensity tactile feedback may not produce the optimal interaction efficiency,whereas the appropriate feedback can improve interaction efficiency.The analysis of the applicability of the interaction model shows that the predictability of the model is affected by the strength of tactile feedback.Secondly,electrovibration and vibration tactile feedback with fixed intensity were used to study the qualitative effects of these two tactile feedback separately or synergistically on the interactive efficiency and accuracy of drawing gestures.Besides,we quantitatively analyzed the usability of the CLC pen-based drawing gesture interaction model through the bare-finger tactile interaction of mobile terminal.The results of qualitative analysis shown that electrovibration and vibration tactile feedback worked synergistically has a significant effect on the interaction performance and user preference,and demonstrated the availability of the model.Thirdly,the influence of tactile feedback in different combinations on interactive performance is analyzed by applying electrovibration and vibration tactile feedback together in linear and exponential forms respectively,combined with panning gesture operation as research content.The usability of traditional Fitts' law,Steering law and Meyer's law under tactile feedback combined in exponential form condition is analyzed.The results show that the application of tactile feedback in exponential form combination can achieve better interaction efficiency than other combinations and Meyer's law can better describe panning gesture operation in terms of definition and model predictability.In this paper,the effects of electrovibration and vibration tactile feedback with different strengths and modes on interaction performance and model of mobile terminal are studied.The Steering Law which is more suitable for electrovibration tactile feedback condition is proposed and verified.The application of two different combinations of tactile feedback and interactive tasks was studied to verify the usability of the traditional interaction model.The conclusion of this paper provides a theoretical reference for the application of tactile feedback in mobile terminal interaction.
