technologies

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