Repeatability and Aimability

With the vertical axis working and ability to control launching speeds testing was conducted to determine how consistently the balls could be launched.

The balls are noticeably different sizes. A small difference in pressure results in quite a difference in size, and even with a consistent pressure the balls are not all manufactured identically.

Having the launcher at a fixed position and fixed speed proved to work quite well for consistently launching the balls.

The below shows a few balls being fired in a consistent location toggling the square on and off.

Following this test we tested firing with vertical control.

Though left and right control will be added shortly but with the vertical axis we were able to shoot in a vertical line, there is some inconsistencies side to side but these should be reduced when left and right control is added.

In other tests we noticed that sometime the ball hits the correct location but then the frame reads the balls location when it bounces back out, which can be at a different angle. More analysis of the IR frame sensor data as well as how far the frame should be from the wall will be.

The wall has the following stackup. With the frame too close to the diffusion fabric it will sometimes move into the frame area, especially when struck by a fast moving ball. With the frame too far from the diffusion fabric, it makes the interface a challenge to use for the player as they expect to see a reaction when they touch the fabric where the lights are displayed, not when their hand passes through the frame a few inches from the fabric.
