Gesture-Controlled Lottery Terminal with Motion Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional lottery terminals lack an engaging and intuitive user interface for interacting with users, relying on static displays and manual input methods, which can lead to decreased user engagement and inefficient transaction processes.
Innovation Solution
Implementing a gesture-controlled lottery terminal system that utilizes a graphical user interface and motion capture technology to detect user gestures in 3D space, allowing users to interact with lottery options, receive payments, and dispense tickets through a combination of body movements, facial expressions, and audio feedback, while also providing dynamic content and real-time updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional lottery terminals use static displays and manual input methods, then device complexity is reduced, but user engagement and interaction efficiency deteriorate
Solution Approach 1:
The patent replaces traditional mechanical input devices (buttons, keyboards, touchscreens) with a motion capture system that uses cameras and computer vision algorithms to detect and interpret user gestures in 3D space. This substitution of mechanical interaction with optical sensing and software-based gesture recognition resolves the contradiction by enabling intuitive, engaging interaction without adding physical complexity to the terminal hardware.
2Adaptability or versatility
If gesture control technology is implemented, then user interaction becomes more intuitive and engaging, but device complexity increases
Solution Approach 1:
The motion capture system serves multiple functions: it detects user presence, recognizes various gesture types (hand waves, finger points, body movements), determines user intent, and controls different aspects of the lottery terminal interface. This multi-functionality approach resolves the contradiction by consolidating diverse interaction capabilities into a single versatile system rather than adding separate specialized devices for each function.
Solution Approach 2:
The patent introduces a computer vision processing system as an intermediary between the user's physical gestures and the terminal's response. This intermediary layer captures raw camera data, processes it through gesture recognition algorithms, and translates it into meaningful control commands, thereby enabling versatile interaction without requiring direct complex hardware modifications to the terminal itself.
3Ease of operation
If motion capture devices are used to detect gestures in 3D space, then ease of operation improves, but measurement precision requirements increase
Solution Approach 1:
The system performs preliminary calibration and setup of the motion capture environment before actual use. This includes establishing baseline gesture patterns, configuring detection sensitivity thresholds, and pre-mapping gesture zones in the 3D space. By preparing these measurement parameters in advance, the system achieves high detection accuracy without requiring complex real-time processing during user interaction.
Solution Approach 2:
The patent implements feedback mechanisms where the system provides visual or auditory confirmation when gestures are successfully detected and recognized. This feedback loop allows users to verify that their gestures were accurately captured, and the system can adjust detection parameters based on detected gesture patterns, thereby maintaining high measurement precision while keeping operation simple for users.

AI summary
A method including providing a lottery terminal that includes a graphical user interface and a motion capture device to facilitate a user to play in a lottery. The method further includes displaying, on the graphical user interface, a first image with content that includes drawing lottery tickets, instant lottery tickets, lottery games, dynamically-generated animations, and advertisements and detecting, by the motion capture device, a gesture of the user in a three dimensional space surrounding the lottery terminal. The method may further includes displaying, on the graphical user interface, a second image with content based, at least in part, on the gesture of the user; receiving, by the lottery terminal, a payment from the user for playing the lottery; and distributing, by the lottery terminal, a lottery ticket, based, at least in part, on the gesture of the user.
