The Sky Blues have won just five league matches at the Ricoh Arena this term compared to 10 away from home as they prepare to welcome an out-of-sorts Swindon side who are currently just six points above them in the table.
But caretaker boss Carsley is keeping his cards close to his chest regarding how he plans to change his side's fortunes on home soil.
He said: "We've been racking our brains all week on things we can do differently and obviously the proof will be in the pudding that we've come up with a successful way of doing things. We'll be changing it around on Saturday."
It may not necessarily be an issue of personnel as Carsley could opt to name the same side who claimed a 2-0 victory away at high-flying Bournemouth in midweek.
Defenders Richard Wood (groin) and Blair Adams (knee) remain sidelined for a couple more weeks while striker Stephen Elliott is set to miss the rest of the season with his knee injury.
