Abstract

The invention discloses a wearable fingertip force feedback device, comprising: Velcro, finger cots, strings, torsion springs, torsion spring shafts, sliders, guide rails, transition plates, motors, couplings, lead screws, Nut, first lead screw bracket, base, first finger ring, second finger ring and second lead screw bracket. The invention can output the feedback force to the fingertips of the human body to enhance the force-tactile perception in the human-computer interaction.

Description

technical field [0001] The invention relates to the technical field of force feedback, in particular to a wearable fingertip force feedback device. Background technique [0002] Today, technologies such as somatosensory, multi-touch, virtual reality, and remote operation have gradually penetrated into various fields such as medical care, education, and games as several ways of human-computer interaction. Taking virtual reality as an example, although it has matured in terms of vision and hearing, it still has insufficient haptic perception, that is, it lacks a control mechanism that can realize force feedback and integrate with virtual reality technology to enhance the technology. The sense of immersion and reality brought by users. Although some existing devices such as PhantomOmni, Omega, and Delta can realize force feedback, they mainly provide feedback force to large limb joints of the human body and the range of action of force feedback is limited. Therefore, developi...
