AR Text Input Interface Without Controllers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing AR devices require additional accessories like handles or remote controllers for text input, which cause inconvenience and burden in daily use scenarios.
Innovation Solution
A text input method and apparatus that enables direct text input on a head-mounted display device without the aid of accessories, utilizing a text input control with concentric rings or a nine-grid configuration to facilitate character selection and input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If accessories like handles or remote controllers are used for text input in AR devices, then text input functionality is achieved, but device complexity and user burden increase
Solution Approach 1:
The patent extracts the text input control from external accessories and integrates it directly into the AR device's display interface. The text input control, including multiple child controls for character selection, is rendered as a graphical overlay on the display screen, allowing users to interact with text input functionality using only the AR device itself without requiring additional handles or remote controllers.
Solution Approach 2:
The AR device provides text input capability through its own display and control interfaces. The system enables users to input text by interacting with child controls displayed on the screen, making the device self-sufficient for text input operations without relying on external accessories.
2Productivity
If a text input control with multiple child controls is displayed on the AR device, then text input efficiency is improved, but the interface complexity increases
Solution Approach 1:
The text input control is segmented into multiple child controls, where each child control corresponds to a specific character or set of characters. This segmentation allows users to efficiently select characters by interacting with individual child controls rather than typing each character individually, thereby improving text input efficiency while organizing the interface into manageable discrete elements.
Solution Approach 2:
The text input control serves multiple functions through its child controls - each child control can represent different characters or character combinations. This multi-functionality allows the interface to handle various text input scenarios (single characters, common word fragments, etc.) through a unified control structure, improving productivity without proportionally increasing complexity.

AI summary
A text input method and apparatus, and a non-transitory computer readable storage medium are provided. In the text input method, in response to determining that a head-mounted display device is triggered for text input, the head-mounted display device displays a text input control in a target picture displayed by the head-mounted display device. The text input control may include a plurality of first child controls that correspond to characters, and each first child control displays corresponding characters respectively. Furthermore, in response to determining that a target first child control among the plurality of first child controls is triggered, the head-mounted display device determines target characters corresponding to the target first child control, determines a text to be inputted based on the target characters, and inputs the text to be inputted into a text input box displayed on the target picture.
