Solution Overview

Problem

Current media playback systems provide limited incorporation of haptic feedback, failing to enhance the media experience with sophisticated tactile and touch-based sensations during the playback of media content on mobile devices.

Innovation Solution

Implementing haptic technologies in mobile devices, such as smartphones and tablets, to provide synchronized tactile and touch-based feedback, including texture, pressure, and thermal sensations, by establishing a connection with local content receivers and receiving haptic data signals to enhance the user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If haptic feedback is incorporated into media playback systems, then user experience is enhanced with tactile sensations, but device complexity increases

Engineering Contradiction:
Improveuser experience enhancementVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system separates haptic feedback generation into independent haptic effects that can be individually controlled and synchronized with specific media events. Each haptic effect is a discrete component that can be managed separately, reducing overall system complexity while enabling rich tactile feedback experiences during media playback.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a haptic feedback manager as an intermediary component that coordinates between media playback and haptic effect generation. This manager synchronizes haptic effects with media events and manages the complexity of coordinating multiple haptic components, shielding users from the underlying complexity while delivering enhanced experiences.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple haptic effects are provided simultaneously, then immersion is enhanced, but energy consumption increases

Engineering Contradiction:
Improveimmersion levelVSAvoidenergy consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The system activates haptic effects periodically or event-driven rather than continuously, synchronizing tactile feedback with specific media events such as scene changes, sound effects, or visual impacts. This approach provides immersive experiences at key moments while allowing the device to conserve energy during static or less engaging segments of media playback.

Inventive Principle:
Principle #19Periodic action

3Adaptability or versatility

If haptic feedback is continuously provided, then user engagement increases, but user comfort decreases due to overstimulation

Engineering Contradiction:
Improveuser engagementVSAvoiduser discomfort
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system applies haptic feedback selectively and partially rather than continuously, providing tactile sensations only when they add value to the media experience. By synchronizing haptic effects with specific media events and avoiding overuse, the system maintains user engagement while preventing the discomfort that would result from constant or excessive haptic stimulation.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

Methods, apparatuses, systems, and computer-readable media for using haptic technologies to provide enhanced media experiences are presented. According to one or more aspects of the disclosure, a computing device, such as a smart phone, tablet computer, or portable media player, may establish a connection with a local content receiver. Subsequently, the computing device may receive, from the local content receiver, a sensation data signal that specifies one or more haptic effects to be provided at a particular time relative to playback of a media content item received by the local content receiver. Thereafter, the computing device may provide the one or more haptic effects.
