Embodiment Construction

[0024] The present invention will be further explained below in conjunction with the accompanying drawings.

[0025] like figure 1 , figure 2 , image 3 As shown, the finger exoskeleton wearable force-tactile interaction device includes a connecting rod 1, a finger exoskeleton base 11, and a motor 7; the connecting rod 1 includes a bottom plate 1-1 close to the inner side of the middle segment of the finger, and the front and rear of the bottom plate 1-1 The two ends are respectively connected to the upwardly folded front flap 1-3 and the rear flap 1-2, and the front flap 1-3 is connected to the middle panel 1-4; the front flap 1-3 and the rear flap 1-2 are respectively There are through holes for fingers to pass through. The connecting rod 1 is designed as an exoskeleton according to the characteristics of the human finger. When in use, the middle segment of the finger passes through the two through holes in the connecting rod 1 to be fixed, and the distal segment of the ...

Abstract

The invention discloses a touch screen-oriented finger outer skeleton wearable force-touch sense interaction device, which can provide multiple modes of force sense and vibration touch sense feedbacks for human fingers. A plane four connection rod mechanism and a direct-current motor are used as an execution mechanism to provide continuous controllable force sense feedback for an operator. Different types of touch sense feedbacks are provided for the operator by controlling vibration amplitude and frequency of a voice coil vibrator, and the authenticity of touch sense perception can be enhanced in an interaction process; a vibration motor can enhance edge information of an image, and can achieve a collision detection effect. Finally, three-dimensional feature information of a virtual object in a touch screen, such as texture, an outline shape, and roughness can be expressed. The interaction device has important meaning in improving the authenticity and the fidelity of force touch sense feedbacks.

Description

technical field [0001] The invention relates to the field of virtual reality technology, in particular to a wearable force-tactile interaction device with a finger exoskeleton facing a touch screen. Background technique [0002] Virtual reality technology enables users to have a sense of "immersive" immersion in terms of vision and hearing. With the development of virtual reality technology, it is becoming more and more important to introduce haptic perception into the virtual environment, especially for tasks that require dexterous operation such as virtual assembly and teleoperation. attach importance to. The sense of touch refers to the human perception of heat, pressure, vibration, sliding, and surface texture and roughness through the skin, while the sense of force refers to the movement and force information received by the human tendon receptors, including the position , speed, pressure, inertial force and other characteristics. Traditional human-computer interacti...
