Sensorium Modes

Note: This whole section is personal campaign terminology. They owe much inspiration and pioneering to Elround4 on the Myth Weaver boards.

Game Mechanics

Mostly, these sensorium modes are for color in the game but they can have mechanical effects too with the GM's permission. Generally, the balance is between focusing on what you're doing and being able to tell what's around you. You can't do both well and they are usually inversely related. Some situations that might arise are:
  • Too Many Interfaces: The optional rule from Panopticon (p. 170) is that hackers watching multiple systems can get a penalty from -10 to -30 because there's simply too much for them to monitor at once. This can also apply to someone with multiple sensoria going at the same time, such as someone jamming a bot who hasn't cut off his morph's senses.
  • Arm's Length Hacking: While it can provide a penalty to only interact with a computer sensorium minimally, this also protects hackers from basilisk hacks and other nasty surprises.
  • The Comfort of Silence: Researching, programming, or composing with most of one's external sensorium turned off can really help an ego focus. Working with reduced input and full-sensory deprivation can help with checks and give bonuses to stress tests because of the personalized feel of this space.
  • A Color Never Seen Before: When experiencing a sense or a sensorium mixture never encountered before which is truly exotic, GMs may ask for an alienation test like sleeving into a new morph. Characters will probably get bonuses but if they fail the sensations are just too much for comfort.

The main split of sensorium modes that even the infugee reinstantiated five minutes ago understands is VR vs. AR. In a word, the difference between these types of artificial sensoria is "replacement." Virtual reality feeds are meant to replace your morph's senses while augmented reality is woven into them as additives to one's basic sensorium. Some old-fashioned types figure there are just five senses to play with, and indeed most people with mesh inserts work with just the traditional senses: visual, audial, tactioception/haptic perception (touch), gustation (taste), and olfaction (smell).

There are more ways that one's morph senses the environment, however, and most sensorium-connected programs also include ways to utilize less-familiar senses such as thermoception (heat/cold), proprioception (body position), nociception (pain), and equilibrioception (balance). Depending on one's morph, the baseline sensorium might also include echolocation, magnetoception, or radioception (radioactivity). While many have enhanced vision that can see into parts of the electromagnetic spectrum which flats cannot, this is generally considered part of sight. On the other hand, many computer scientists argue that the intuitive way AGIs experience computer code is fundamentally different from the way other transhumans do and is a unique sense in itself, something they call datareception.

Regardless of the number of senses (the most common figure is nine), when they are turned off, replaced by other sensoria, or mixed with new feeds the results can take some getting used to. The two types of VR commonly mentioned are full-sensory replacement (FSR) where the ego experiences seven or more external senses, and partial-sensory replacement (PSR) where only four to six new senses are fed. Once the replacement senses get down to three or fewer, most people stop considering this "real" VR. For AR feeds the spectrum is a little wider, ranging from minimal-input AR (just one or two sense feeds) to multi-input AR (two to four sense feeds) to overlay-AR (five or more sense feeds). Generally, when an ego uses VR senses they turn their other senses off while with AR senses they leave them on, but this is not always the case. Sometimes, users want to have multiple sensoria playing at once or they want a head that is clear except for specific inputs. Non-deprivation means that an ego has muted none of his senses (or sometimes just one), partial deprication means that several are muted (usually two to five), while full deprivation means that all senses are muted or nearly so (six or more feels pretty isolating).

The different modes are summed up in the chart below. While general numbers of senses (added for VR and AR or subtracted for deprivation levels) are given, these are just rules of thumb. In particular, for the very-important senses of sight, hearing, and touch, consider these counting double in terms of what people are likely to call that mode. For example, turning off thermoception to avoid being chilled is still non-deprivation to most people, but turning of tactioception so that your whole body is numb is worth "double" more minor senses and would be considered partial deprivation.

Full-VR (7+) Partial-VR (4-6) Overlay-AR (5+) Multi-AR (2-4) Minimal-AR (1-2)
Full Deprivation (6+) simulspace (hyper) delving
delving (shallow) delving N/A
Partial Deprivation (2-5) jamming filtered jamming skinning
(über) scanning
(über) scanning scanning
Non-Deprivation (0-1) N/A (thick) skinning (semi) skinning (semi) skinning

From roughly least- to most-extreme, the sensorium modes you'll hear about most of the time are…

  • Silent Mode: With all artificial sensoria turned off and just relying on your morph's senses, the world is a lot less noisy. However, for most in the system, this is also a fairly off-putting experience since it means your messages are piling up, your muse can't talk to you, there are no hints to help you navigate, you can't look at anyone's mesh id or rep-ratings, etc. People hardly ever go into silent mode unless they are eccentric, theatrical or both… or unless they are Firewall agents with a need to avoid any digital input. Note that silent mode (turning off all artificial sensory input) is totally different than private mode (turning off all output and most artificial input), though they might appear the same on the outside.
  • Media Mode: This is the mode that most of the system exists in for most of their lives. There is no sensory deprivation and only some minimal augmented reality input: music playing in the background, navigation markers showing in entoptics, etc. Depending on how many feeds are turned on, this mode might be classified as minimal-AR (only music or only visual) or as multi-AR (a muse and its voice, a chime and a tingle when a message comes in, etc.). Most folks rarely make these distinctions, though, and "media mode" can cover a lot of ground.
  • Scanning: Sometimes called "multifocusing" or "twinning," scanning means that a person is splitting his attention between two sensoria. He is usually watching the one right in front of him and also some pretty involved AR objects, so involved that a few of his "normal" senses are turned off to allow the focus. In cases where there is a lot of extra input (multi-AR or overlay-AR), people sometimes call this über-scanning and it becomes increasingly obvious that the person is very distracted by mesh insert feeds.
  • Skinning: The common practice of "skinning" or applying an AR sensorium over most of your surroundings, is what gets many people through the day when they have tedious jobs or live in cramped habs. This can run the gamut from multi- to overlay-AR, but if you aren't turning off your other major senses it's more likely to be called "semi-skimming." It's all well and good to see a lush jungle around you, for example, but if you still hear the noise of Mitre around you and your equilibrioception still tells you you're in microgravity, the experience is not quite there. On the other hand, if you "skin" your environment with ultra-real partial-replacement VR feeds then you're really transported into the fantasy, something that skinning enthusiasts call "thick skinning."
  • Delving: Complicated computer tasks and detailed conversations require full attention and most people go into a mode-type called "delving" to accomplish this. Because delving requires full-sensory deprivation, it's also called "drooling," "trancing," or even "dreaming." Transhumans delving stare off into space and sometimes unconciously let their faces or bodies go slack (depending on whether they turn off their proprioception or equilibrioception), but internally they are listening, watching, smelling, or otherwise experiencing nothing but a detailed overlay-AR. If the sensory feed is not enough to approximate a full sensorium (such as with a multi-AR) people call this "light delving" (though the trance-like expression is still there), while watching detailed VR feeds are "hyper-delving." Unlike those jamming a bot or experiencing a simulspace (see below), transhumans delving are still aware of their surroundings, though they are clearly missing the majority of what goes on around them.
  • Jamming: When a person transfers the sensorium of a bot or pod remotely to replace his own sensorium, this is called "jamming." It can only be done with VR-level feeds and is typically done with full-sensory replacement VR. Partial-VR is also an option though one doesn't get the full experience, prompting the term "filtered jamming." While they are hardly "dead to the world," a jamming transhuman will be unaware of all but the biggest changes taking place around his physical morph and then only through the senses that remain active. A typical jammer will have sight, hearing, taste, proprioception, thermoception, and maybe one or two other senses muted but retain their morph's tactioception so that any shaking that occurs or anything bumping into them will still register on some level.
  • Simulspace: This is the ultimate replacement of one's sensorium. Typically all senses (and that really is all) are muted and replacement VR feeds are the only sensorium experienced by the ego. In cases of low-sophistication or low-bandwidth, the simulspace may be a partial-sensory replacement VR only but it is still immersive and detailed or one wouldn't bother calling it a simulspace.
