The former Leeds boss also wanted his squad to recognise the honour of representing England and so he invited luminaries such as Gary Neville and Corporal Simon Brown to hammer home the message.
After training had finished on the University of Leeds' 1st XV pitch, and while the players were mobbed for autographs, Lancaster reflected on mission accomplished.
The make-up of his team to face Scotland at Murrayfield a week on Saturday is coming together and the England captain will be announced on Monday.
"When I got the job and thought about what I'd do for the camp there were a number of objectives," Lancaster said.
"To reconnect with the public, to engage with the media, to train in conditions that are similar to Scotland, to listen to people from outside the sport.
"But mainly it was about building a culture and getting people on the same page from a technical and tactical point of view.
"We have gone a long way to achieving that. The players have been fantastic. They are hungry, they want to work hard and they want to get the show back on the road and it has been a great week.
"But it is a 10-stage process and next week we have to narrow down our focus and get into the technical and tactical detail for what is a massive game for us."
Neville, Corporal Brown and England rugby league captain Jamie Peacock addressed the squad in a private function last night and between them delivered a powerful message.
Corporal Brown was shot through the face while serving in Iraq in 2006 and, by all accounts, a pin could have been heard dropping in the room as he spoke.
Neville won 85 caps for England but retired feeling unfulfilled because England never came close to winning anything other than at Euro 96, when Terry Venables' side lost a semi-final penalty shoot-out to Germany.
The former Manchester United full-back invoked the spirit of that tournament - and the national fervour that surrounded it - in a bid to highlight how powerful a nation's support can be.
"He talked about the power of playing in Euro 96 when the country was behind them, the pressure of being an international player and the opportunity of it," Lancaster said.
"He finished off by saying everyone is behind you, that England football want England rugby to do well.
"Jamie Peacock said the same, that England rugby league want England rugby union to do well. It was the the same from Hugh Morris, the England cricket manager.
"They will all be watching and that is a powerful thing."
The Rugby Football Union offered free tickets to schools and clubs across Yorkshire for today's open training session, the first of its kind outside Twickenham.
The school allocation went within four hours. At least 30 mini-buses and coaches pulled into the training venue from all over the region.
The supporters were treated to the rare sight of coach Andy Farrell and his son Owen Farrell running in the same back line.
"It gives the public an opportunity to see England train - but it reminds the England players about what it means to be an England player.
"That was probably the most important thing for me."
Lancaster's efforts thus far have been praised by RFU executives, whose "reputational damage rebuild plan" is addressing the on and off-field problems that beset English rugby in 2011.
Those same efforts were described, almost dismissively, as "good media work" by Sir Clive Woodward, who went on to point out that the real challenge begins in Test week.
Lancaster is acutely aware of what lies ahead for England in the defence of their Six Nations title.
"I have loved this week but the excitement will build towards the game and coaching is about dealing with big games," Lancaster said.
"It will be an exciting week. Next week we will get into the real detail, get the side finalised and get organised."
