Human Factors Analysis And Application Of Pressure Input In Pen Interaction

In this paper,we mainly introduce the pen pressure as the control quantity into the pen interactive technology,the user's ability to control the pen pressure,and according to the experimental results of the design of two pressure-based interactive technology:pen-based interactive pressure-based small target Choose the technology and the introduction of pressure pen scrolling technology.Firstly:the study of the user's ability to control pen pressure.We first analyzed the pressure distribution of the electronic pen itself when using pen-type interaction,and then we analyzed the ability of people to control the pressure when introducing some visual feedback.Experiments show that when the visual effect feedback is introduced,the experimenter controls The ability to significantly increase the pressure;experimental analysis also shows that the introduction of pressure after the pen-type sliding task can still be described using Steering law.Secondly,we designed a pen-based focus-based zoom target selection technique that combines standard cursor selection techniques with variable focuing selection techniques and uses pressure as a discrete variable to switch between these two Mode.We compared the technology with Take Off technology and improved regional cursor technology,and found that the time taken to select the target will vary with the target width.When the target width is 2 and 4.the pen-based zoom-based zoom target selection technique is significantly better than the Take Off technique and the improved area cursor technology;when the target width is 8,there is no significant difference between the three.There are no significant differences in the three techniques of error rate.Thirdly,we designed a pen-style document rolling technique that introducing pressure as a rolling rate parameter into the pen-line rolling technique.The greater the pressure applied by the experimenter,the greater the rolling rate.The experimental results show that when the pressure parameters are introduced,the arc-shaped stroke scrolling technique and the linear-stroke scrolling technique are superior to those when the pressure parameters are not introduced.Finally,According to the experimental results we also put forward some guidelines on pen pressure technology.First of all,our experiments show that the pressure is able to effectively improving the pen-type interactive technology.Then when designing pressure interaction techniques,pressure can be mapped to discrete variables or pressure continuous variables to achieve pressure-based interactive application scenarios.
