Dynavox does support switches--so if he is having a hard time accessing the symbols on the Dynavox, he can hit a switch to scan through the symbols for him. When it highlights the symbols he wants, he can press the switch to select. I'm not sure of his motoric abilities and if using his hand to hit the switch would be the best option...but it's a start. He can either use directed scanning (he's in control of scanning) or automated scanning( he hits a switch to start the scanning process and then hits the switch again to select the symbol).
Another option would be to look at how the Dynavox is set up. He maybe could use larger symbols for a bigger target to hit with his hand. Or a keyguard can be put on the Dynavox to assist in isolating a finger and keep his hand from accessing other buttons if he is sliding his hand up/down the touchscreen to get to the desired symbol. Dynavox also has a hold/release time, so you could set it to where he may have to leave his finger on a symbol for a few extra seconds before it accepts his choice. Hope this helps, not seeing or knowing more about his abilities or where the problem is in his access...these will help give you some ideas of where to start, though.
