When pressing a letter, sometimes it'll select another letter on the screen. For example, if I press on H, sometimes it will show that I pressed G instead. This could be because the letters on the screen are too small, or my fingers are too fat, or simply because the touch screen navigation is not accurate enough.
This holds the computer to the front screen and is adjustable. The A in the first image is slotted into the A in the second image. Same for B. It supplies the batteries to the device. The problem with the design is that when trying to remove the device from its stand, alot of force is used, which results in the user applying so much force that the device hits the glass window or fingers are crushed against the glass. This is dangerous and could damage the product.
My suggestion for the first problem is to implement a surface acoustic wave for the touchscreen monitor if not already chosen for the touch screen navigation system. It works by having transducers and reflectorsat the x and y axis of the screen, and when there is a touch at the glass, waves are absobed, causing a touch to be detected. This would allow a high touch resolution and also allow the highest clarity for the images behind the glass. I thought about introducing a stylus but that would easily be lost, or would cause to be too time consuming and fiddly to take out and store, considering if someone is on the road, they would want navigations fast.

For the second problem, of removing the device from it's stand, I would suggest, instead of removing the device upwards, it should be pulled out towards the user. I changed the port and the slot in piece, labelled A and B in the above images, so that they are horizontal, and so the wire comes out from the back of the device instead of from the bottom. I kept these lower to the stand, so as not to change up the inside of the device too much. This way, when removing the device from its stand, the user can push against the stand, in order for the device to slip away from the stand easier. Also, they can use two hand to do this, allowing more control.
