摘　　要：力触觉是重要的非视觉信息来源之一,通过触觉向人类传递丰富的信息被广泛应用于各个领域。为解决基于振动的力触觉反馈中所存在的振动器与皮肤之间接触力不可调和重复穿戴时接触力不一致而影响振动感知的问题,提出了一种利用气囊来调节振动器与皮肤之间的接触力的方法,并以此设计了一种新型手臂力触觉反馈装置。为验证装置的有效性,设计了不同的振动强度识别实验。实验结果表明,对于参与实验的受试者,振动器与皮肤之间的接触力对振动强度的识别的影响是显著的,在气囊内外气压差为15 mbar时,振动强度的识别率最高,为76. 67%。Force/tactile sense is one of the most important sources of non visual information. The way to deliver rich information to human by tactile sense is widely used in different fields. In the force/tactile feedback based on vibration,the vibration perception is affected by the unadjustable contact force between the vibrator and the skin and the inconsistent contact force during repeated wearing. In order to solve this problem,a method for adjusting the contact force between the vibrator and the skin is proposed using gasbag,and a new device for arm force/tactile feedback is designed. To test the efficiency of the device,the experiment to recognize different levels of vibration was designed. For the subjects of this experiment,the results show that the influence of contact force on recogniting different levels of vibration is obvious. When the air pressure difference between the inside and outside of the gasbag is 15 mbar,the recognition rate is the highest,which is 76. 67%.
