Solution Overview

Problem

Current entertainment gaming devices primarily provide users with limited tactile feedback, relying mainly on visual and auditory cues, which can distract players from the game and fail to effectively communicate game-related information in a haptic manner.

Innovation Solution

The integration of an electromagnetic device with a touchscreen switching element, featuring a resilient front panel with permanent magnets and excitable coils, generates vibrations that provide tactile feedback to users, allowing for game-related information to be communicated haptically, regardless of the game's status, and can be combined with visual and acoustic cues.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If visual and auditory feedback are used to communicate game progress, then information delivery is effective, but user engagement and immersion are limited

Engineering Contradiction:
Improveinformation deliveryVSAvoiduser engagement
Core Design Contradiction:
Loss of informationVSAdaptability or versatility

Solution Approach 1:

The feedback system is segmented into multiple independent channels: visual feedback through display devices, auditory feedback through speakers, and haptic feedback through vibration devices. Each channel operates independently to convey different aspects of game progress, allowing the system to maintain effective information delivery while enhancing user engagement through multi-sensory stimulation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent merges multiple feedback modalities (visual, auditory, and haptic) into a unified feedback system. By combining these different sensory channels, the system delivers comprehensive game progress information while significantly improving user immersion and engagement compared to single-modality systems.

Inventive Principle:
Principle #5Merging (Combining)

2Loss of information

If user attention is diverted to check game progress, then awareness of game state improves, but focus on actual gameplay deteriorates

Engineering Contradiction:
Improvegame state awarenessVSAvoidgameplay focus
Core Design Contradiction:
Loss of informationVSProductivity

Solution Approach 1:

The system implements continuous haptic feedback through vibration devices that are activated based on game events. This provides users with real-time awareness of game state changes through tactile sensations, eliminating the need to visually check the display and allowing users to maintain full focus on the gameplay while staying informed about progress and outcomes.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The vibration device acts as an intermediary between the game system and the user, translating game events into tactile feedback. This intermediary channel conveys game progress information directly to the user's sense of touch, bypassing the need for visual attention and enabling continuous gameplay focus while maintaining awareness.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If multiple feedback channels (visual, auditory, tactile) are integrated, then user immersion improves, but device complexity increases

Engineering Contradiction:
Improveuser immersionVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The switching element serves multiple functions: it acts as a user input device for controlling the game, a visual display element through backlighting, an auditory feedback source through integrated speakers, and a haptic feedback device through vibration motors. This multi-functionality reduces the need for separate components and minimizes overall system complexity while providing comprehensive multi-sensory feedback.

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

Solution Approach 2:

The patent combines multiple feedback mechanisms into integrated assemblies where visual displays, speakers, and vibration devices are co-located with switching elements. This merging approach creates a compact unified feedback system that delivers multi-sensory information without requiring separate distributed components, thereby managing device complexity.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A gaming machine comprises a housing (1), in which a game sequence controller, at least one display device (49) for displaying a gaming unit (3) and at least one switching element (26), actuatable by a user and in contact with the game sequence controller, are arranged. At least one electromagnetic device (27) coupled to the game sequence controller is associated with the switching element (26) and, if the switching element (26) is actuated, generates information that can be detected tactilely by the user in the form of a vibration and/or a change of the actuating resistance depending on the course of the game.
