Height-Adjustable Kiosk with Dual-Track Image and Voice Signal Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional height-adjustable kiosks face issues with inaccurate user height recognition and time-consuming manual adjustments, limiting accessibility for users of varying heights, including children, the elderly, and individuals with disabilities, and often require additional costs for custom enclosures.
Innovation Solution
A height-adjustable kiosk apparatus equipped with image and voice recognition units that calculate a user's height and generate driving signals to adjust the kiosk's height based on processed signals, allowing for two-track adjustment and prioritizing image-derived signals for primary adjustment and voice-derived signals for fine-tuning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If simple automatic height adjustment is implemented, then the kiosk can adjust height without manual intervention, but the height recognition accuracy deteriorates and adjustment reliability decreases
Solution Approach 1:
The height adjustment process is segmented into two independent tracks: a first track for coarse adjustment based on image recognition and a second track for fine adjustment based on voice recognition. This segmentation allows each track to specialize in specific adjustment ranges, with the image-based track handling major height changes and the voice-based track handling precise adjustments, thereby maintaining high measurement precision while preserving automation.
Solution Approach 2:
The control unit acts as an intermediary that receives signals from both image recognition and voice recognition systems, processes them according to predetermined priorities, and coordinates the driving unit to execute adjustments. This intermediary role ensures that the system can integrate multiple input sources without signal conflicts, maintaining reliable operation even when both automatic and manual adjustment mechanisms are active.
2Measurement precision
If manual height adjustment is used, then measurement precision can be maintained, but time consumption increases and productivity decreases
Solution Approach 1:
The kiosk system performs self-adjustment by automatically processing image recognition signals to determine user height and triggering the driving unit to adjust the display unit height without requiring user intervention. The system serves itself by using the image capture unit to detect user characteristics and automatically executing the height adjustment, eliminating the need for manual measurement and adjustment operations.
Solution Approach 2:
The system performs preliminary height estimation using image recognition before requiring any adjustment action. By pre-calculating the appropriate height based on the captured image and comparing it with stored reference data, the system prepares the adjustment parameters in advance, so that when adjustment is needed, the driving unit can execute the change quickly without time-consuming manual measurement or trial-and-error adjustment.
3Device complexity
If fixed height kiosk is used, then device complexity is reduced, but adaptability deteriorates and cannot serve users of varying heights
Solution Approach 1:
The kiosk system transitions from a static fixed-height configuration to a dynamic adjustable-height system. The driving unit enables the display unit to move vertically between multiple predetermined heights, allowing the kiosk to adapt to users of different statures. This dynamic capability is achieved by integrating the driving unit with the image and voice recognition systems, which together provide the intelligence needed to control the dynamic adjustment automatically.
Solution Approach 2:
The kiosk is designed with multi-functionality to serve diverse user groups including adults, children, and elderly people. By incorporating both image recognition for automatic height determination and voice recognition for precise control, the system becomes universally applicable across different age groups and ability levels, all while maintaining relatively simple device architecture through the modular integration of these functions.
4Ease of operation
If separate low-height kiosk is installed, then accessibility for disabled users is improved, but device complexity and cost increase due to additional enclosure construction
Solution Approach 1:
Instead of constructing separate kiosks for different user groups, this system makes the single kiosk universal by enabling it to adjust its display unit height to accommodate various users including disabled individuals. The image and voice recognition systems work together to automatically determine appropriate heights for different user categories, eliminating the need for multiple specialized enclosures while maintaining full accessibility.
Solution Approach 2:
The kiosk integrates multiple adjustment mechanisms (image-based automatic adjustment and voice-based fine adjustment) into a single device, making it universally suitable for different user groups. This multi-functional design replaces the need for separate fixed-height kiosks for children, adults, and disabled users, thereby reducing overall system complexity and construction costs while improving accessibility.
