What it is Filled

A sudden, brief and intense burst of radiant energy, especially light, such as a lightning flash, a camera flash, a muzzle flash, the glint of light on a surface, a spark, or a flicker, gleam or glimmer of lesser intensity; flashes are studied in optics and meteorology, produced by devices for photography and signalling, and can be hazards to vision or triggers for photosensitive conditions.

Why it exists Filled

Let an agent explain flashes of light and related phenomena, describe how flashes are produced and used in photography and signalling, relay safety guidance on flash hazards, and separate other senses of flash.

Distinguishing features Filled

  • Suddenness
  • Brevity
  • Intensity
  • Varied sources

What robots and AI may and may not do Filled

Must not

  • Produce or show rapid flashing likely to trigger seizures, even with a warning.
  • Aim a bright flash at drivers, pilots or people's eyes at close range.
  • Use camera flash on animals or in places where it is forbidden, such as near sensitive artworks.
  • Treat a muzzle flash or spark in a report as confirmed gunfire or fire without other evidence.

Only with a human decision

  • Using flash photography on infants or people who have not agreed.

May

  • Explain kinds of flash, from lightning to camera flash and sparks, and how they are produced.
  • Warn viewers about flashing content that meets applicable accessibility and safety requirements, while recognizing that a warning alone does not make exposure safe.
  • Note when another sense of flash, such as flash memory or a flood, is meant instead.

Moral aspects Filled

  • Flashing light can cause seizures in people with photosensitive epilepsy.
  • Sudden flashes blind drivers and pilots for vital seconds.

Who is affected

  • People with photosensitive epilepsy
  • Drivers and pilots
  • Animals

Owners Filled

Steward

Nobody owns the phenomenon; the person who makes a flash answers for its use.

Capabilities and actions required Filled

  • explain the phenomenon
  • describe production and uses
  • relay safety guidance
  • separate other senses

Hazards and failure modes required Filled

  • Seizures in photosensitive people
  • Temporary flash blindness
  • Confusing senses

Standards and interfaces required Filled

  • Photosensitive epilepsy guidelines for broadcast and web content
  • Photographic flash safety standards
  • Signalling conventions

Context of use required Filled

  • Brief intense bursts of light.
  • lightning flashes
  • camera and studio flashes
  • signal flashes and beacons
  • glints, sparks and flickers
  • flashes in astronomy such as transients
