technologies
- visual signal: external gadgets, VR, AR, MR, XR
- audio signal: external (headphones), stereo signal
- induction of pseudo-visuals in brain possible with audio stimulation
- current best XR good enough to trick senses into considering an XR object “real”
- taste sense can be electrically induced (sources)
- smell sense, and the rest currently resort to the external simulation
- hypno/dream induction devices are available on the market
- computing power considerations
- mobility considerations
- networking considerations (throughput required at least in order of 1Gbytes/s)
