Reaction test
First Claim
1. Apparatus for providing a test for humans, the apparatus comprising a device providing a visual shape which is perceived to be moving along a path at varying speed by the human undergoing the test, the device being operative to vary the visual shape at a plurality of points along the path, and further including signalling means operated by the human undergoing the test as each change of shape is perceived, the device being operative to vary the speed of the shape and to vary the shape independent of operation of the signalling means by the human.

Abstract
A reaction test for determining the reaction of humans to change consists of a moving shape which changes from time to time, the change being signalled by a person being tested, and apparatus recording the delay between the change and the subsequent signal. The moving shape increases speed during the test, and the chance may be a chance of shape/colour or any other detectable change. The test results are useful in detecting or confirming certain medical conditions.

- 1. Apparatus for providing a test for humans, the apparatus comprising a device providing a visual shape which is perceived to be moving along a path at varying speed by the human undergoing the test, the device being operative to vary the visual shape at a plurality of points along the path, and further including signalling means operated by the human undergoing the test as each change of shape is perceived, the device being operative to vary the speed of the shape and to vary the shape independent of operation of the signalling means by the human.
- 8. Apparatus for providing a test for humans, the apparatus comprising a device providing a visual shape which is perceived to be moving along a path at varying speed by the human undergoing the test, the device being operative to vary the visual shape at a plurality of points along the path, and further including signalling means operated by the human undergoing the test as each change of shape is perceived, wherein the device is a personal computer, a monitor of the computer providing a screen across which the shape moves, and the signalling means comprising a computer mouse, and wherein the shape repeatedly changes from a circle to a square, and from a square to a circle.
- 10. A method of testing the reaction time of a human to a visual stimulus, the method comprising the steps of providing a visual shape which the human undergoing the test will perceive to be moving along a path at an increasing speed, varying the visual shape at a plurality of points along the path, providing signalling means for operation by the human as each change of shape is perceived, and wherein the increase in speed and variation in visual shape are independent of the signalling means.

14. A method of testing the reaction time of a human to a visual stimulus, the method comprising the steps of providing a visual shape which the human undergoing the test will perceive to be moving along a path at an increasing speed, varying the visual shape at a plurality of points along the path, providing signalling means for operation by the human as each change of shape is perceived, setting a test duration, setting an initial speed of movement of the visual shape, setting a final speed of movement of the visual shape, setting the number of changes of shape required, determining an acceleration profile for said visual shape, and determining random time periods between each change of shape, each period being not less than 1 second and not more than 10 seconds.
- 15. A computer, monitor and mouse in combination, the computer being adapted to control the monitor to create a test producing a visual shape moving across the monitor for a predetermined period, the visual shape changing at intervals and the visual shape increasing speed from the beginning to the end of a test, and the computer having a memory to record the time of each change of the visual shape and the time of the next subsequent input from said mouse.
