Head-Controlled Voice Input for Faster VR Text Entry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for inputting content while wearing virtual or augmented reality headsets, such as using handles to control a cursor on a virtual keyboard, are inconvenient and inefficient.
Innovation Solution
A method and device for voice input using head control, where a user controls a head-turning motion to navigate a pointing cursor in a voice input interface, performs speech recognition, and integrates a virtual reality device with an interaction unit, input text generation unit, and processing unit to manage head movements for efficient text input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a user uses a handle to control a cursor on a virtual keyboard, then text input can be performed, but the operation is inconvenient and input efficiency is low
Solution Approach 1:
The patent replaces the mechanical handle control system with a voice-based input system. Users speak commands naturally without physically manipulating a handle, substituting mechanical interaction with acoustic signal processing. This resolves the contradiction by eliminating the cumbersome mechanical control while maintaining text input capability through speech recognition.
Solution Approach 2:
The voice input system serves multiple functions: it allows users to input text, navigate interfaces, and control the virtual environment simultaneously through speech. This multi-functionality improves both efficiency and convenience compared to the specialized handle control method, which could only perform basic cursor movement and selection.
2Productivity
If head control is used to control cursor movement in the voice input interface, then input efficiency is improved, but the device complexity increases
Solution Approach 1:
The patent introduces head movement detection as an intermediary control mechanism between the user and the voice input system. The interaction unit detects head movements and translates them into cursor positioning commands, serving as a natural bridge that leverages existing head-tracking capabilities without requiring complex new hardware.
Solution Approach 2:
The system dynamically adjusts cursor positioning based on real-time head movement detection. The interaction unit continuously monitors head position and updates cursor location accordingly, creating a dynamic control system that responds naturally to user head movements rather than requiring static positioning or complex manual adjustment.

AI summary
Disclosed is a method for achieving voice input by using head control. A head control indication cursor is suspended at the position of an input control within a first preset time in a voice input interface according to a first head rotation motion of a user; speech recognition is carried out, and input text is generated in a speech conversion result textbox; whether the head control indication cursor moves into the voice conversion result textbox within a second preset time is determined according to the first head rotation motion; and the input text is added to the input control.
