VR Display Flicker Reduction via Sensor-Based State Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Virtual Reality (VR) devices experience a flicker phenomenon when displaying images, particularly noticeable in a still state due to slight user movements causing sensor measurement variations, leading to pixel differences and flicker.
Innovation Solution
An image display method that determines the activity state of a VR device using sensor data to switch between flicker suppression and forwarding processing modes, processing images based on whether the device is in a still or moving state to adapt the display and reduce flicker.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If image forwarding process is used in still state, then display responsiveness is improved, but flicker phenomenon occurs due to sensor measurement variations
Solution Approach 1:
The system dynamically switches between forwarding process and flicker suppression process based on the detected activity state of the VR device. When the device is in a still state, the flicker suppression process is applied to eliminate pixel differences caused by sensor variations. When the device is in a moving state, the forwarding process is applied to maintain display responsiveness. This dynamic adaptation resolves the contradiction between display stability and responsiveness.
2Reliability
If flicker suppression process is applied continuously, then display stability is improved, but processing time increases
Solution Approach 1:
The system periodically evaluates the activity state of the VR device using sensor data and alternates between forwarding process and flicker suppression process based on the detected state. This periodic state-based switching ensures that flicker suppression is applied only when necessary (in still states), maintaining display stability while minimizing processing time overhead by avoiding continuous application of the suppression process.
3Measurement precision
If sensor measurement frequency is increased, then activity state detection precision is improved, but device complexity increases
Solution Approach 1:
The system uses sensor data as an intermediary to indirectly determine the activity state of the VR device rather than directly measuring complex activity parameters. By evaluating sensor measurements (accelerometer, gyroscope, magnetometer data) to infer whether the device is in a still or moving state, the system achieves accurate activity state detection with relatively simple processing logic, resolving the contradiction between measurement precision and device complexity.
