A court-ordered mental health assessment will be carried out on the man known as the 'Naked Rambler'.
Stephen Gough appeared unclothed in the dock for his trial at Kirkcaldy Sheriff Court on Thursday.
The 53-year-old represented himself during the trial where he was accused of committing a breach of the peace by refusing to wear clothes after he was released from Perth Prison on July 20.
Gough, originally from Eastleigh in Hampshire, was convicted of the charge, which stated that he walked naked in a public place near a children’s play park in the Townhill area of Dunfermline in Fife.
He has spent much of the past six years in prison on similar charges.
Sheriff James Williamson deferred sentence on Gough until next month and ordered social workers to produce a report assessing Gough's emotional and mental health.
Concern
After finding Gough guilty of the charge, Sheriff Williamson expressed concern about his demeanour.
The sheriff told Gough: "I have to say, there were certain points in your evidence, certain points in your summing up, where I was a bit concerned about your emotional behaviour. I was a bit concerned as to whether or not you were in control of yourself.
"What I'm going to do, and you may not understand this, is defer sentence at this stage for a criminal justice social work report. I want someone independently to see what they make of you and whether or not your mental health is all it should be.
"Because unfortunately, in the absence of any good reason otherwise, you're going to end up serving prison sentence after prison sentence."
Gough, who has long fought for his right to appear naked in public, appeared tearful at points during the hearing when witnesses recalled their shock and discomfort at seeing him wandering about unclothed.
His voice cracked as he told the court: "There is nothing about me as a human being that is indecent or alarming or offensive."
At other stages of the trial he said: "I'm challenging beliefs about the human body. I expect people to disagree with what I'm doing."
He also explained: "We are beautiful because we are human beings. We are all the same. I've nothing to be shameful about."
'Mortified'
The former Marine left Perth Prison on July 17 without being re-arrested by Tayside Police, as has happened on previous occasions.
Three days later, however, he was arrested in Cairncubie Road, Townhill, near Dunfermline, after members of the public reported him walking near a play park.
PC David Moffatt, 30, said he approached Gough in a police car and asked him to cover up, but Gough refused.
He told the court: "I asked him to cover up and he refused to do so. I asked him if he was prepared to at least step into the police vehicle so we could talk and he refused to do so as well.
"I think his attitude was that he had been travelling through towns for the last few days. He didn't understand why things should be different from region to region. He said something along the lines of 'a naked body isn't offensive'."
Another witness, 37-year-old Michelle Solway, said she was in her her car with her daughter when she saw Gough.
"I just felt it was disgraceful," she said, adding that her child had covered her eyes at the sight and was "mortified".
Mrs Solway said: "She was quite happy up until that point and then she was really shocked. It's not something to expect, going along the road. It's not good for children. They shouldn't be subjected to that."
Sheriff Williamson said he was satisfied beyond reasonable doubt that Gough was guilty of breach of the peace.
The 53-year-old was remanded in custody and will be sentenced at Kirkcaldy Sheriff Court on September 13.
