HMD Golf Game Input Device with Tactile Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current golf games using head-mounted displays (HMDs) lack intuitive gameplay, as they do not effectively simulate the real golfing experience, leading to a disconnect between virtual and actual golfing motions.
Innovation Solution
A game system that includes a head-mounted display, an input device capable of tracking user motions, and a stimulus generation mechanism to provide tactile feedback when the golf club contacts the ground, allowing users to swing a rod-shaped input device to control a player character in a virtual golf game, enhancing immersion and realism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a head-mounted display is used to provide virtual reality images, then the sense of immersion into the video world is enhanced, but the gameplay becomes less intuitive and realistic
Solution Approach 1:
The patent applies feedback by providing tactile stimulation to the user's hands when the virtual golf club contacts the ground. The stimulus generation section delivers vibration or tactile feedback through the input device, creating a sensory loop that connects the user's physical actions with the virtual game events, thereby enhancing both immersion and intuitiveness simultaneously
Solution Approach 2:
The patent utilizes mechanical vibration by driving the stimulus generation section to vibrate the input device held by the user. This vibration occurs specifically when the golf club contacts the ground in the virtual environment, providing a physical sensation that mirrors the virtual action and makes the gameplay more intuitive and realistic
2Ease of operation
If traditional game controller buttons are used to swing a golf club, then the game is easy to operate, but it significantly deviates from real golf playing
Solution Approach 1:
The patent applies copying by using a rod-shaped input device that replicates the form and handling characteristics of a real golf club. Instead of using abstract buttons, the user physically swings the device like a real club, and the system copies the motion dynamics to control the player character, maintaining both ease of operation and realism
Solution Approach 2:
The patent implements feedback by providing tactile stimulation when the virtual golf club contacts the ground, creating a sensory connection between the user's physical swing and the virtual game events. This feedback loop makes the simplified control mechanism feel more realistic and faithful to actual golf playing
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enables a more intuitive and immersive golf gaming experience by providing tactile feedback and accurately simulating golfing motions, making the game more engaging and realistic.
Implementation Method 1
the control section drives a stimulus generation section disposed in the input device to stimulate the user's hands gripping the input device
Data Source
AI summary
Provided is a golf game that is readily intuitively playable by a user. An input reception section receives an operation input indicating a motion of an input device gripped by the hands of the user. A control section controls a motion of a player character in a game space in accordance with the operation input. An image generation section generates a game image. When a golf club held by the player character comes into contact with the ground in the game space, the control section drives a stimulus generation section disposed in the input device to stimulate the user's hands gripping the input device.
