Quick guide to Auto Trigger:
If you want G-Trigger to behave differently for different active program, it's now possible. For example, you want left to right for playing next track, right to left for playing previous track, only if Windows Media Player is active then create a new profile, assign left to right for next track, right to left for previous track and check "Auto Trigger" with program name as wmplayer.exe. Bingo!!! Its done.

How G-Trigger works:
G-TriggerService.exe application runs all the time and polls the G-Sensor to get current position of the device. It polls G-Sensor for about 10 times a second and observes the positions of the device. It keeps track of last 5 positions and scans all the 5 positions and checks if any shake is detected. If shake is detected it looks for action and triggers an action.

FAQ:
1. Does polling of G-Sensor all the time damages it?
-It does not seems to damage sensor by polling but I don’t take any responsibility in a case. Use it at your own risk!

2. Does G-TriggerService impacts my device’s battery power?
-Yes! It runs all the time as soon as your device is awake and it keeps on polling the G-Sensor, so it will consume some battery power. Although, I am running it all the time since I developed, I don’t see any legible battery consumption. Though you need to benchmark if you want to see exact battery consumption.

3.How much memory does G-TriggerService eats?
-G-TriggerService takes around 500KB when OSD is off and takes around 1MB if OSD is on.

The dev posted this about the shake detection:

Ok.. Let me try to explain the shaking gestures

Hold the mobile phone facing yourself and perform following:

Left to Right:
Quickly move the phone from current position towards right hand side for about 6 inches (Increase speed during motion from slow to fast and suddenly stop at the end to feel the shock)

Right to Left:
Quickly move the phone from current position towards left hand side for about 6 inches (Increase speed during motion from slow to fast and suddenly stop at the end to feel the shock)

Top to Bottom:
Quickly move the phone from current position to downwards for about 6 inches (Increase speed during motion from slow to fast and suddenly stop at the end to feel the shock)

Bottom to Top:
Quickly move the phone from current position to upwards for about 6 inches (Increase speed during motion from slow to fast and suddenly stop at the end to feel the shock)

Front to Back:



Hold the phone facing yourself and near to you.
Quickly move the phone from current position to far away from you for about 6 inches (Increase speed during motion from slow to fast and suddenly stop at the end to feel the shock)

Back to Front:
Hold the phone facing yourself and little far from you.
Quickly move the phone from current position to nearer to you for about 6 inches from the last position (Increase speed during motion from slow to fast and suddenly stop at the end to feel the shock)

Hope this helps

Set up Toggling
Also, if you don't want to leave it on all the time, there is a way to toggle it on/off other than start/stopping within the app. You can assign a softkey (or hardkey) to "G-TriggerService.exe"

It is located under Program Files> G-Trigger> G-TriggerService




If G-Trigger is already running, it can be turned off as well, although you'll get the following pop up:



However, when toggling it back on, you will not receive this pop up, making it more convenient to do while not needing to look at your device. There is about a 1 second delay when you toggle on, but honestly it's pretty negligible.
