I have used both taste and smell before. As for hearing it is pretty much overused for me. I would say overall its hitting a 50/50 split with sight.
In order for me to use taste and smell I have to visualize what something would smell or taste like. I find that if I do this I can actually smell/taste whatever I am visualizing though not as intensively as actually experiencing it.
If I integrate all senses to make 10 imaginary loci . . . testing . . . :
Definitely feels more realistic, recall to objects can be done by smell or taste rather than walking through the journey. Feels a bit strange to taste or smell a memory but I guess its doable. Seems more ‘fun’ but I am not sure if it greatly helps on recall. This is tempting me to make a smell/taste system.
I seem to interlink the smell and taste more to the objects and sound to the environment on default.
I was actually going to share my loci but when I started typing them up I sort of wrote a story of eating nice food and strolling across while somehow having tea, so I will restrain on that.
