Head-Mountable Display Image Cropping via Head Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital image cropping methods rely on input devices like mice or trackpads, which are not intuitive or natural, especially for adjusting image composition in real-time.
Innovation Solution
A method and system using a head-mountable display (HMD) that receives movement data from sensors, allowing users to pan or tilt their head to crop digital images naturally, generating a cropped image based on these movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional input devices like mice or trackpads are used for image cropping, then precise control over cropping parameters can be achieved, but the operation becomes less intuitive and more complex
Solution Approach 1:
The patent replaces mechanical input devices (mice, trackpads) with head movement sensing technology. The HMD captures natural head movements through sensors and translates them into cropping operations, substituting mechanical interaction with biological movement detection. This makes the cropping operation more intuitive as users naturally move their heads to indicate desired crop regions.
Solution Approach 2:
The system allows users to perform cropping operations using their own head movements without requiring external input devices. The HMD detects and processes the user's natural head motions directly, enabling self-service cropping where the user's body becomes the input mechanism, eliminating the need for separate control devices.
2Productivity
If real-time image cropping is performed during capture, then immediate composition adjustments can be made, but processing time and computational resources increase
Solution Approach 1:
The patent performs preliminary cropping operations during the image capture phase rather than after capture. By detecting head movements in real-time and applying crop transformations immediately, the system prepares the image composition beforehand, allowing users to see the final cropped result before saving or processing the full-resolution image.
Solution Approach 2:
The system applies cropping transformations to a preview or reduced-resolution version of the image in real-time, rather than processing the full-resolution image. This partial action approach allows immediate composition adjustments without the computational burden of processing complete high-resolution images, balancing speed with quality.
Data Source
AI summary
Methods and systems are provided for cropping a digital image based on movement data. A wearable computing device may receive image data. The wearable computing device may comprise a head-mountable display (HMD), and the HMD may comprise a viewing frame. The image data may be displayed within the viewing frame. The wearable computing device may receive movement information indicative of at least one movement of the wearable computing device. The at least one movement of the wearable computing device may comprises at least one of a pan of the wearable computing device or a tilt of the wearable computing device. In response to receiving the movement information, the wearable computing device may perform a cropping action on the image data so as to generate a cropped image. The cropped image may represent a reduced portion of the image data.
