What are senses? what are emotions? Are they the same? Is an emotion what I sense? Do senses lead to emotions? Does a sense always lead to the same emotion?
What is a picture? Captured visual senses. What is a song? Captured audio senses. What is a video? Captured audio-visual senses.
Now, let's give our sci-fi minds a tweak and imagine (After all, today's sci-fi is tomorrow's reality) a day where we can capture ALL senses in some way. So, the way a picture captured what you could 'see', you can now capture EVERYTHING you can see/feel/smell/hear. Let's call it a sense capsule. The way we see a picture, imagine that you can 'play' this sense capsule again - which means, you get 'immersed' in the same environment (where you hear/smell/feel/see the same thing that you did when the sense capsule was created) that the capsule was captured in.
A sense capsule of this form will give a truly complete conjunction of what I sense at that instant. Imagine capturing your best friend's wedding this way. Six months after the wedding, you can actually 'play it back' where all the senses are generated again. Imagine how amazing it would be to play the memorable moments of our lives again and again - to live them again.
This brings me to the line between senses and emotions. A picture of an estranged friend may not evoke the same emotions that it would have back then. A sense capsule will make you feel like you seeing the same event again - but there is no guarantee that you will feel the same way as you did when the event first happened.
Senses lead to emotions. Strangely, not the same one always.
