The Carrow Road clash is a sell-out and the visitors arrive on the back of a 6-1 thumping of fellow relegation candidates Sunderland on Monday night.
One win in eight games has dropped the Canaries right into the relegation mix but a win would effectively secure top flight football for the third straight season.
"It's a game that we very much want to win - it's a home game so a chance to get valuable points," said Norwich manager Hughton.
"Our home form has been excellent. It's always been about what we do.
"Villa are on the back of a good result but it's about concentrating on our strengths. We have a fabulous crowd who will get behind us. To be in this division means everything to us."
Defender Sebastien Bassong is expected to be fit after an ankle problem, but fellow centre-half Michael Turner (groin) remains out.
Forward Kei Kamara will play the last game of his loan spell from Sporting Kansas City, with no confirmation yet of whether the deal will be made permanent.
Hughton said: "We have until Monday to make the decision, and there have been conversations between us, but those will be kept private as we concentrate on the job in hand, and that is making sure we put ourselves in a position on Saturday where we are going to get a result."
The manager, meanwhile, also "absolutely dismissed" reports winger Anthony Pilkington was set for a summer move to Stoke and that West Brom were planning to hijack Norwich's agreed £8m transfer of Dutch forward Ricky van Wolfswinkel from Sporting Lisbon should the Canaries get relegated.
He added: "It's always a tough job, but you do the job because of the challenges. We can speak about the challenge now - the challenge of going into these last three games trying to get the results that we need. They're there throughout the season.
"You do this job because of them, and you never shy away from them, but you also do the job because you have a confidence in what you're doing. We need to take that confidence into these last three games."
