The document discusses how humans experience reality through their senses and technology has expanded this over time. It states that sight alone is 1/5 of reality, sound alone is another 1/5, and the combination of sight and sound through television and film is 2/5. Current research aims to also include scent to make it 3/5. The ultimate goal is to develop a way for humans to experience all 5 senses at once and achieve a full 5/5 perception of reality, but there is no set date for when this may be possible due to the complex work still required from scientists and engineers worldwide.
