Abstract: Abstract: Motion loading of mobile terminal is an effective way to lessen users anxiety caused by when waiting for what is loaded. With regard to the design creativity, its important to explore how its design elements influence such anxiety caused by waiting. In the present study, time-distance perception is used to characterize the sense of anxiety while waiting. Through the prospective experimental paradigm and time-distance replication method, the time-distance perception experiment of the subjects in the simulated situation is carried out with speed and style as independent variables. The experimental results show that different types of motion loading all demonstrate a reduction on time perception, while the motion-loading speed exerts a more noticeable influence, notable, especially in the course of the acceleration. When the interaction of dynamic type and velocity has a significant influence on time perception, the time-distance perception of acceleration and cartoon combined loading is the shortest, and the time-distance perception of uniform speed and text class combined loading is the shortest, but deceleration and three dynamic styles combined loadings have no significant difference in the effect of time-distance perception. In conclusion, the users’ time-distance perception is related to the speed and type of motion loading via reasonable combination of speed and type which could effectively reduce users’ perception and then reduce their anxiety. The results of this study provide scientific evidences for mobile-loading motion design.
