AI Technical Summary

Technical Problem

Existing technologies struggle to provide rich haptic feedback in touchscreen-based human-computer interaction scenarios, resulting in an inadequate user experience, especially when operation is difficult due to visual and auditory limitations.

Method used

By generating a stereo map based on the target image, extracting texture information and calculating vibration distribution information, vibration feedback is used to simulate tactile sensation, including vibration intensity, sharpness, and duration, to enrich the tactile feedback.

Benefits of technology

Simulate the tactile feel of real objects on touchscreen devices to enhance the user's tactile experience, enable blind operation, and improve the user's interactive capabilities in environments with limited vision and hearing.

Abstract

The application provides a method for simulating haptic feedback, and relates to the technical field of multi-modal interaction, which simulates touch by vibration feedback and improves user experience. The method comprises the following steps: displaying a target interface, the target interface comprising a first control for displaying a target image; detecting a touch operation on the target image; obtaining first vibration distribution information corresponding to the target image; the first vibration distribution information is generated based on a first stereogram; the first stereogram is generated based on texture information of the target image; and generating vibration corresponding to the texture information based on the first vibration distribution information.
