HMD Tilt Input for Content Manipulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable computing devices lack a user-friendly mechanism to apply manipulative actions to displayed content objects, as different users have varying preferences for how content is displayed, and existing solutions do not efficiently accommodate these differences.
Innovation Solution
A head-mounted device (HMD) system that includes a processor and data storage with user-interface logic to receive data on the direction and extent of tilting, allowing for various manipulative actions such as zooming, scrolling, and rotating of displayed content objects based on the device's tilt, enabling users to interact with content in a personalized manner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional input methods are used in wearable computing devices, then the device structure remains simple, but the ease of operation deteriorates due to lack of efficient content manipulation mechanisms
Solution Approach 1:
The patent replaces traditional mechanical input interfaces (buttons, switches, touchscreens) with a motion-based control system. The wearable device detects head movements through inertial sensors and translates these natural motions into content manipulation commands, eliminating the need for complex physical input mechanisms while improving ease of operation.
Solution Approach 2:
The system utilizes the user's natural head movements as the input mechanism, allowing the body's own motions to serve as the control interface. This self-service approach converts incidental head movements into meaningful input actions, eliminating the need for separate input devices and simplifying the overall system while enhancing operational ease.
2Adaptability or versatility
If fixed content display methods are used, then the device complexity remains low, but the adaptability deteriorates as different user preferences cannot be accommodated
Solution Approach 1:
The patent implements dynamic content display that adapts to user preferences through motion-based control. The system allows users to manipulate content properties (zoom level, scrolling, rotation) in real-time based on their head movements, transforming static display into a dynamic, adaptable interface that responds to user intent without requiring complex pre-programming for each user preference.
Solution Approach 2:
The motion-based control system serves multiple functions simultaneously: it detects user intent, controls content navigation, adjusts display parameters, and adapts to different user preferences all through a single unified interface. This multi-functional approach enhances adaptability while avoiding the complexity of implementing separate control mechanisms for each function.
3Productivity
If no content manipulation mechanism is provided, then the device complexity remains simple, but the ease of operation worsens as users cannot efficiently interact with displayed content
Solution Approach 1:
The patent replaces the absence of a manipulation mechanism with a motion-based control system that detects head movements and translates them into content manipulation commands. This substitution enables efficient content interaction (zooming, scrolling, rotating) without requiring complex physical interfaces, thereby improving productivity while maintaining relatively simple device architecture.
Data Source
AI summary
Methods and devices for applying at least one manipulative action to a selected content object are disclosed. In one aspect, a head-mounted-device (HMD) system includes at least one processor and data storage with user-interface logic executable by the at least one processor to apply at least one manipulative action to a displayed content object based on received data that indicates a first direction in which the HMD is tilted and an extent to which the HMD is tilted in the first direction. The at least one manipulative action is applied to a degree corresponding to the indicated extent to which the HMD is tilted in the first direction.
