==Definition==
Low Resolution Indicators are a key principle of calm technology that conveys information through simplified signals requiring minimal cognitive processing. These indicators provide essential information at a glance while remaining in the periphery of attention until needed.

==Summary==
Low Resolution Indicators work by reducing complex information to its most essential elements, presenting it in a form that our brains can process pre-attentively - before conscious attention is engaged. This approach builds on our natural ability to perceive and understand environmental cues without active focus.

Consider how we naturally understand the weather by glancing at the sky - we don't need detailed meteorological data to know if it's likely to rain. Low Resolution Indicators mirror this natural cognitive process. A simple color change in a light bulb can convey weather forecasts, allowing us to absorb this information peripherally just as we would notice darkening clouds.

The effectiveness of Low Resolution Indicators comes from their alignment with our perceptual systems. For example, our visual system processes color and basic shapes pre-attentively, meaning we can understand these signals without consciously focusing on them. This is why traffic lights use color rather than text - red, yellow, and green convey their meaning instantly without requiring us to read.

The "low resolution" aspect is important - low resolution indicators deliberately avoid detailed information in favor of essential signals. Like a car's fuel gauge that shows "empty" versus "full" rather than exact liters of fuel, Low Resolution Indicators provide just enough information for the context while remaining easy to process peripherally.

==Key Characteristics==
Low Resolution Indicators should:
* Present information in a form that can be processed pre-attentively
* Reduce complex data to essential signals
* Use natural perceptual mappings (like up=more, down=less)
* Remain in the periphery of attention until needed
* Avoid requiring conscious interpretation or focus

==Examples==

* The battery icon on mobile devices: shows charge level through a simple shape fill
* Traffic lights: convey complex right-of-way rules through three colors
* Weather lights: indicate forecast through color changes
* Volume indicators: show sound level through bar height
* Progress bars: communicate completion status through simple linear fill

==Design Reccomendations==
When creating Low Resolution Indicators, designers should focus on:

* Identifying the essential information that needs to be conveyed
* Choosing representation methods that map to natural perceptual abilities
* Removing unnecessary detail that could create cognitive load
* Testing that the indicator can be understood without conscious focus
* Ensuring the indicator remains in the periphery until needed

==Relationship to Calm Technology==
Low Resolution Indicators exemplify calm technology's goal of moving information between center and periphery of attention. They allow complex systems to communicate important information without demanding constant attention, helping technology remain calm while still being informative.
