The world around is made up of information that competes for our attention. What is necessary? What is not?
When we design products, we aim to choose the best position for user interface components, placing the most important ones in the most evident and accessible places within the screen. Equally important is the design of communication. How many are notifications are necessary? How and when should they be displayed? To solve this, we can be inspired by the principles of calm technology.1
If a technology works well, we can ignore it most of the time. A teapot tells us when it is ready, and is off or quiet the rest of the time. A tea kettle can be set and forgotten, until it sings. It does not draw constant attention to itself until necessary. A tea kettle's whistle brings information from another room to one's attention.
An inner office window provides an understanding of whether someone is busy or not without the need to interrupt them.
The Jawbone Up has a single button and a colored status light. The device can be set to buzz after a short nap or at the optimium sleep cycle for a good night of sleep. It counts movement in the background without requiring additional action from the wearer. The device syncs to the user's phone through the audio jack and gives a summary of the wearer's individual day in sleep and physical activity.
This simple sign tells you whether the lavatory is occupied or not. No need to translate it into multiple languges. The simple icon is either occupied or not.
The humble Roomba Vacuum cleaner chirps happily when it is done and emits a sad tone when it is stuck. There is no uncanny valley present in this technology. Roomba doesn't have a spoken language, just simple tones. This makes it easy to understand what Roomba is saying, and elimates the need to translate the tone into many different languages.
Sleep Cycle is a mobile application that monitors your sleep and allows you to track times of deep sleep and REM. You can set an alarm in the app and Sleep Cycle will wake you up before the time at the best place in your sleep cycle with a soft noise or buzz. Because the haptic alert occurs under your pillow, you can configure it so that you can wake up without anyone else being affected by the alarm.
A smart badge is simple. Smart badges are small, wearable technologies that don't require a charger, user interface or operating system. Simply touch a provisioned smart badge to a door or elavator panel and you'll easily gain access.
Use haptics or touch to inform someone of important information. Many people set their phones to buzz, but other products such as the LUMOBack Smart Posture Sensor buzzes you when you exhibit poor posture. Touch is a high resolution of human sensation. A lot of information can be conveyed with no visual or auditory requirement.
A good trend graph is all about making the formerly invisible visible. The Sleep Cycle app graphs sleep over time, compressing that long term data into an easily accessible format. Be patient: good data may a long time to collect, but it is well worth the wait! Displaying data in a elegant way is one of the most important aspects of trend graphs. Elegance is about information and comprehension, not just visual appearance.
Status lights are farily common on video cameras. A device is active when the red 'record' light is on. Status lights can be used for more than just recording. Our daily travels are mediated by the simple colors of traffic lights. A light that shows the weather is far more calm than a weather ssystem that constantly calls attention to itself. Think about how to use different colors of light to inform and encalm in your products.
A status tone is a quick way for a device to let a person know whether it needs attention or not. Products that have a positive tones upon completion, or negative tones when stuck are more likely to be helped by their human owners.
A Status Shout is similar to a Status Tone but can be much louder and more urgent. Smoke alarms, tea kettles and microwaves all use shouts to alert people to their status. Ambulances use Status Shouts to alert people to make way for an emergency. Tornado warnings utilize Status Shouts to help neighborhoods get to a safe place and out of the tornado's path. Status Shouts should be reserved for very important information.
Popup alerts are perhaps the most common form of alert, but they can quickly overwhelm people when not used correctly. Alerts should be used when deleting a piece of content, for an emergency, or when someone has specifically opted into a piece of content or stream. Otherwise, try to think of ways to alert a person using the other senses.
A simple status light on a timer can make for a calm and informative notifier. An orange light that turns on at sundown or reminds you to brush your teeth.
Use a delay or interrupt during a change of state. For example, when the headphones of an iPhone become disconnected, the music player automatically pauses the music.
