Solution Overview

Problem

Conventional messaging systems rely on visual and auditory feedback, which fail to provide a compelling interaction for users, lacking intuitive haptic cues about message content.

Innovation Solution

Implementing physics-based tactile messaging by representing messages as virtual objects with physical parameters, allowing users to interact with these objects through sensors and actuators, generating haptic effects that simulate real-world interactions within a virtual message environment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional visual and auditory feedback are used in messaging systems, then the system implementation is simple, but the user interaction becomes unconvincing and lacks intuitive cues about message content

Engineering Contradiction:
Improveuser interaction qualityVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines multiple feedback modalities (visual, auditory, and haptic) into a unified messaging system. The haptic feedback module integrates with the display and audio components to provide synchronized multi-sensory feedback, creating a more compelling user interaction experience while managing system complexity through modular integration.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The messaging system is designed to provide multiple types of feedback (visual notifications, auditory alerts, and haptic patterns) through a unified interface. The haptic feedback module can deliver various vibration patterns and tactile sensations to convey different message states, making the system versatile in communicating information across multiple sensory channels.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Loss of information

If basic haptic feedback is used to accompany visual and auditory cues, then the system remains simple to implement, but the haptic feedback provides minimal information about message content

Engineering Contradiction:
Improvemessage content informationVSAvoidhaptic system complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent applies different haptic feedback patterns and intensities to specific message types and user actions. Different vibration patterns (e.g., continuous, pulsing, rhythmic) are assigned to different message categories, providing localized information about message content through tailored haptic responses rather than generic feedback.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The haptic feedback system varies multiple parameters including vibration frequency, amplitude, duration, and pattern to encode different message information. By changing these physical parameters dynamically based on message content and user interaction state, the system conveys rich information through haptic feedback without requiring complex additional hardware.

Inventive Principle:
Principle #35Parameter changes

3Loss of information

If physics-based tactile messaging with virtual objects is implemented, then intuitive communication of message content is achieved, but the device complexity increases significantly

Engineering Contradiction:
Improvemessage content communicationVSAvoidvirtual environment system complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent creates virtual representations of physical objects (balls, blocks, containers) within the messaging interface that simulate real-world physics interactions. These virtual objects copy essential physical properties such as gravity, collision, and stacking behavior, allowing users to interact with messages through familiar tactile metaphors while the actual physics computation occurs through software rather than physical mechanisms.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system replaces physical mechanical interactions with computational simulations. Instead of requiring actual physical objects and mechanisms to demonstrate physics-based interactions, the patent uses software-based physics engines to simulate gravitational forces, collisions, and object dynamics on the display, with corresponding haptic feedback providing tactile confirmation of these virtual physical interactions.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Systems and methods for physics-based tactile messaging are disclosed. For example, one disclosed method includes the steps of receiving a sensor signal from a sensor configured to sense a physical interaction with a messaging device; determining an interaction between one or more virtual message objects and a virtual message environment, the interaction based at least in part on the sensor signal and a virtual physical parameter of at least one of the one or more virtual message objects; and determining a haptic effect based at least in part on the interaction. The method additionally includes the step of generating a haptic signal configured to cause an actuator to output the haptic effect.
