Virtual Lottery Device Using Camera-Mediated Physical Object Simulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lottery drawing methods on computers can produce biased results when simulating virtual object motion, making it difficult to prove that multiple events occur with intended probabilities, especially requiring extensive testing to validate equal probability outcomes.
Innovation Solution
A lottery device and method that associates random data with positions and marks on virtual objects, simulating their motion through physical operation, and determining results based on these associations to ensure randomness and equal probability outcomes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If lottery drawing is carried out by simulating physical operation of virtual objects in virtual space, then the lottery atmosphere becomes more true-to-life, but the lottery results may become biased depending on the design of the virtual object
Solution Approach 1:
The patent introduces a camera as an intermediary device that photographs the actual physical lottery object (dice, roulette, etc.) and uses the photographed image as the virtual object in the virtual space. This mediator ensures that the virtual object accurately reflects the physical object's actual state rather than relying on pre-designed virtual models, thereby preventing bias while maintaining the true-to-life atmosphere of physical operation simulation.
2Reliability
If extensive testing is conducted to prove that multiple events occur with intended probabilities, then the validity of lottery results can be ensured, but the manufacturing process becomes burdensome
Solution Approach 1:
The patent creates an accurate copy of the physical lottery object by photographing it with a camera. This copied image serves as the virtual object that preserves all the physical characteristics and probabilities of the original. By using this faithful copy in the virtual space, the system maintains the intended probability distribution without requiring extensive physical testing, as the copy inherently reflects the original's probabilistic properties.

AI summary
A lottery device comprises a control unit and a storage unit. The control unit implements a lottery function by executing a program stored in the storage unit. The lottery function comprises an associating function for associating, on the basis of random data, a plurality of positions on a virtual object and a plurality of marks, an operation control function for simulating a motion of the virtual object in a virtual space by physical operation, and a determining function for determining a lottery result on the basis of a mark associated with a position on the virtual object as determined according to a state of the virtual object in the simulation result.
