Welcome

People are told lies every second of every day and although it is human nature to lie it is quite discerning to know who to trust. Research has found that:

  • More than 80% of women admit to occasionally telling "harmless half-truths".
  • 31% of people admit to lying on their CV's.
  • 60% of people lie at least once during a 10 minute conversation and on average, tell 2 to 3 lies.

And on a study undertaken to uncover the percentage of patience that lie to their doctors it was found that 13% of them outright lie to their doctors, 32% of them admit to stretching the truth when providing doctors with personal information and nearly 40% lied about following their doctors treatment plan.

Micro-expressions

Given this it is quite evident that you will not go through life without either being lied to or lying to someone and in my project i hope to create software which uses an ordinary webcam to detect whether or not someone is in fact lying by their facial expressions. This project however will just focus on micro-expressions (involuntary movements in facial muscles) that people subconsciously use when lying. This will be the only source for deducing either truths or lies.
