深視力テスト（三桿法）

[What is the Depth Perception Test (Three-Rod Method)?]
This is a simulation app that allows you to practice the "three-rod method" depth perception test, which is used in driver's license tests and other examinations, on your smartphone.

The app simulates looking through the peephole of a testing machine with three rods, allowing you to train in an environment close to the actual test.

[Test Standards (Compliant with the National Police Agency)]
■ Movement Range
- From the reference position (two rods on the left and right), move a maximum of 10 cm (±10 cm) in both directions (back and front).
- Distance per round trip: 40 cm

■ Movement Speed
- Actual test: Constant speed movement at 5 cm per second (8 seconds per round trip).
- Practice mode: Switchable to 2.5 cm per second (16 seconds per round trip).

■ Passing Criteria
- Three consecutive measurements
- Pass if the average error of the three measurements is within 2 cm.

[Main Functions]
■ Three-Rod Method Simulation
- The two rods on the left and right are fixed; only the central rod moves back and forth at a constant speed.
- Black rods on a white background (display close to the inspection surface).
- The tips of the rods are hidden by the peephole frame (same as the actual test).
- "Stop" the moment they are aligned in a straight line.

■ Test History
- Saves past results (date, time, average error, pass/fail) on your device
- Does not send data to the server

【Recommended for】
- Those who want to practice depth perception tests before obtaining or renewing their driver's license
- Those who want to master the timing of the three-rod method

【Caution】
- This app is for practice and simulation purposes only. It does not guarantee actual test results or pass/fail status on the driver's license test.
