Here is an openidea for an electronic target with a tablet as the target and an IR sensor attached to it.

Below is a link for IR tracking

If we can combine the IR tracking with an app on a tablet then we can use the tablet as the target and attach a small emitter or reflector to the gun and have a iTarget.

Anyone wants to give a shot? [/url]

That's quite fascinating. I wonder what kind of IR ray you would have to use to push enough light and power 10m away.

It's an open idea for discussion, not perfect but I hope it can lead somewhere. If you can help answering your own question regarding IR ray then it might give more people ideas to work off.

I guess the best bet would for you to mount 4 IR LED's at the corners of the target. By having the LED's arrayed with a fair bit of separation you should be able to compute the angles reasonably well as the relative positions change. The sensor should be able to see the LED's from quite a distance.

We fear zombie threads. However, we could find no other reference to this device, or similar:

Has anyone tried this device? Is it worth the $89 stated for Bullseye practice?

IR LEDs on the corners of the target would not have to be very bright at all to stand out from the background.

I've thought a lot about how to do an electronic target / trainer cheaply. All solutions have problems.

Mounting LED beacons on the target would make tracking very easy, but the camera would need to be mounted to the gun, which means adding weight in some location that is not in the sight line.

In addition, the small cheap cameras don't have high enough frame rate to capture movement induced by the trigger. I've tried using HD cameras up to 60 fps and they couldn't capture it. There are higher frame rate cameras available but the cheap ones (under $1,000) accomplish it by reduced resolution. Unfortunately there is not a high volume commercial product that can be adapted to this.

The inverse solution, mounting a Laser diode on the gun and using a camera to capture the dot on the target reduces the weight added to the gun, but still has the frame rate issue and introduces potential safety issues if an IR laser is used since the light is not visible. When I tried it I mostly shot with a red dot sight and "hid" the laser dot behind the red dot. I also tried it with open sights by putting 2 targets up vertically with the laser pointing at the bottom target, hidden by the gun/hand/arm, but sighting and calibration was a pain.

It's been a few years since I looked at this problem. Maybe it's time to try again and see if anything new is on the market.
