HAPTIC FEEDBACK SYSTEM AND METHODS

Smart overview of the Invention

A haptic feedback system is designed to enhance user experience by providing tactile sensations through a wearable device. This device contains one or more regions filled with a non-Newtonian fluid, which allows for dynamic changes in resistance to deformation based on applied forces. The system aims to deliver more diverse and nuanced haptic feedback compared to traditional methods, which often rely solely on vibration.

Components of the Wearable Device

The wearable device can take various forms, such as gloves, socks, sleeves, headbands, or even integrated into head-mounted displays (HMDs). It features enveloped regions that contain non-Newtonian fluids, allowing these regions to change their viscosity and resistance when forces are applied. This adaptability enables the device to simulate a range of sensations, enhancing immersion in virtual environments.

Functionality of Non-Newtonian Fluids

Non-Newtonian fluids behave differently under stress compared to standard fluids; their viscosity can increase or decrease depending on the force applied. For instance, some fluids become more solid-like when subjected to higher forces, allowing users to walk or run across them without sinking. This unique property is leveraged in the wearable device to create varying levels of resistance that can mimic real-world interactions.

Force Providers in the System

The system includes one or more force providers that generate forces to modify the viscosity of the non-Newtonian fluid. These providers can be electromechanical vibrators, piezo-electric actuators, or other mechanisms that apply force directly to the fluid-filled regions. They can be integrated within the wearable device or exist separately, such as in handheld controllers that already provide haptic feedback.

Applications and Benefits

This innovative haptic feedback system has potential applications in gaming, training simulations, and virtual reality experiences. By offering a wider range of tactile sensations, it enhances user engagement and realism. The ability to adjust feedback dynamically based on user interactions represents a significant advancement over traditional haptic technologies.
