Woods has struggled for form since his return to the sport
Tiger Woods has no plans to appoint a new coach for himself as he prepares to defend his title at the Memorial Tournament, which starts on Thursday.
Hank Haney resigned as the world number one's coach of six years earlier this month, citing the scandal in Woods' private life as one of the reasons.
But Woods is happy to rely on his own counsel as he continues his return from injury and five months out of the game.
"I've been using video and working on my game that way," said Woods.
"That's the great thing about technology. I have no plans for a new coach."
And Woods, 34, also conceded that he could see the reasons behind Haney's decision to resign, saying: "I understand it, there's a lot going on. Life is moving forward.
"The last six months have been pretty tough but I'm starting to get into my routine of playing, which is something I haven't done."
Woods has played only three tournaments this year, finishing fourth in the US Masters, missing the cut at Quail Hollow and then quitting during the final round of The Players Championship with a neck injury.
Speaking about the injury which forced him out at Sawgrass last month, Woods added: "The neck feels pretty good.
"It's still not where I want it to be but the inflammation has calmed down. It's a little sore after a good practice but I can recover for the next day which I wasn't able to do prior to this, which is good."
Woods has won four times at Muirfield Village, including three in a row from 1999-2001, and he admits he could not find many better places to warm up ahead of the US Open at Pebble Beach later this month.
"I've always liked this course, I played here in the US Amateur and loved it then and loved it as a pro," he added.
"I have good memories here and it's always nice to come back to a venue where I've played well. Maybe this time I can get four rounds in and get ready for the US Open."
Meanwhile, 2008 Masters champion Trevor Immelman has pulled out of this week's tournament with a wrist injury and will be replaced by American Jeff Maggert.
The 30-year-old South African was limited to 13 events last year due to tendinitis in his left wrist and had surgery in October, which sidelined him for nearly five months.
He returned to action in February but has posted just two top-25 finishes in nine starts this year and has missed the cut in his past two tournaments.
