What does it mean? What are my definitions or starting points?
Extra means "in addition to"
Sensory means "from impulse to sensation"
Design means "to give shape to"
As a sentence I could write: "to give shape to additional impulses and sensations"
But still, what does this mean? I learn how we could tap into our extra senses, how we can pick up those faint or strong signals, recognize them for what they are and translate them into something... I don't know yet.
Another aspect is to develop products that magnifies these signals, like a radio receiver or amplifier. Maybe there are a wide variety of signals out there that we do pick up but they are too weak, too uncorrelated or simply not acceptable in the culture we live in.
These 2 aspects of our extra senses I like to design products and services for.
