Hi, I'm a computer science student and i have been working with my friends on a glove that will detect hand movement and show display it on UNITY. I want to track the hand's upward, downward, left and right movement using accelerometer's data and integrating it to displacement but i have been unsuccessful lately. I'm a beginner and know almost nothing about the accelerometer.
Thanks

Summary: unavoidable errors in the rotation estimation will add up to position errors of kilometers in a few seconds or minutes.
You need some other fixed reference point to measure the glove's location.
ok so what other sensor can i use to detect the position of the glove, it must be cheap and small in size as i'm tracking all 5 fingers per hand. Thanks

People usually use linear potentiometers for the finger position sensors. See this.
Can anyone help me understand if it's possible to track the position of my hand up and down right and left and show it on screen like 3D tracking of my hand using some sensor but not IR sensor.
Thanks

Use a camera.
that's the problem i don't want to use anything that would stick in a particular position. The whole idea is to wear the glove while wearing a VR headset so a person would be moving around himself so the camera could lose the sight of the hand.

Put a small camera controlled by a RPi on the VR. Or use a Pixy camera.
A camera on top of the goggle has the interesting property that when your hand is out of sight of your eyes in the virtual world, it's also out of sight of the camera. Do you need to track the hand motion (as distinct from finger motion) behind your back?
What about a Kinect? Don't they track arm movements with sufficient accuracy? Can you still buy them?

sorry the project is already out of budget our teacher had recommended us to use MPU6050 gyro+accelerometer for detecting motion of hands and now we have 12 of those sensors that can only detect rotations
When you get an assignment like that, you write a paper explaining why the provided equipment won't do the task and then you do something else cool with it.
Even a simple LED spirit level is fun and low cost.
Use RF modules to send signals to each other and then calculate the time taken for the signal to reach back. This requires clocks that are very fast (500 MHz... 1-2GHz) depending how accurate you want the position (to avoid aliasing).
If you can throw it together with cheap parts used how they're meant to be used, then it's hardly a project that would demonstrate anything worth a grade.
Best you can muster (and since you know almost nothing, will still be a challenge) is to create a few distinct hand shapes that can be recognized just by orientation. Peace sign, spidey hand, thumbs up, etc.
You can conclude your project and BS it with something like saying it's just one part of a larger system.
