Head-Mounted Eye Imaging with Dynamic Parameters for Multi-Modal User Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing devices struggle to appropriately acquire a variety of user information, such as facial expressions, iris information, and heart rate, due to varying imaging conditions required for different types of data, which are not adequately addressed by existing technologies.
Innovation Solution
A head mount type information processing device with a determination processing unit to determine acquisition target information, a setting processing unit to set imaging parameters, and an imaging control unit to capture images of the user's eyes based on these parameters, including adjustments to camera position, light source arrangement, and wavelength, to optimize image capture for specific types of user information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If imaging parameters are fixed for a single type of information acquisition, then the device complexity is reduced, but the ability to acquire multiple types of user information (iris, visual line, facial expression, heart rate) is compromised
Solution Approach 1:
The patent implements dynamic switching of imaging parameters based on the type of information to be acquired. The control unit automatically selects appropriate imaging parameters (such as infrared light for iris recognition, visible light for facial expressions) from multiple preset parameter sets, enabling the imaging device to adapt to different information acquisition needs without requiring manual reconfiguration or multiple fixed devices.
2Adaptability or versatility
If multiple imaging parameters are prepared for different information types, then the versatility of information acquisition is improved, but the device complexity and power consumption increase
Solution Approach 1:
The patent employs periodic or selective activation of light sources and cameras based on the current imaging task. Instead of keeping all light sources and cameras continuously active, the control unit activates only the specific combination needed for the current information acquisition type (e.g., only infrared light source and infrared camera for iris recognition), thereby reducing overall power consumption while maintaining full functionality when needed.
3Illumination intensity
If all light sources are activated simultaneously, then the illumination coverage is maximized, but the power consumption and potential user discomfort increase
Solution Approach 1:
The patent applies local quality by activating specific light sources based on the imaging requirements rather than illuminating all areas uniformly. Different light sources (infrared, visible, different wavelengths) are selectively activated according to the specific information acquisition task, providing optimal illumination for each type of sensing while minimizing unnecessary energy consumption and user discomfort from excessive or inappropriate lighting.

AI summary
A head mount type information processing device includes: a determination processing unit that determines acquisition target information according to a scene; a setting processing unit that sets an imaging parameter for acquiring an image that is an image of eyes of an equipment user and corresponds to the acquisition target information; and an imaging control unit that captures the image of the eyes of the equipment user according to the imaging parameter.
