SOS confirmation and countdown for accidental sends

Recognition and recall make different demands

With recognition, the option is present: someone sees “SOS”, “ALL OK” or “I need help” and compares it with their intent. Recall means remembering that a particular icon, long press, sequence or menu item produces an effect. The recognition-over-recall heuristic encourages visible objects, actions and choices.

This is design guidance, not a law that recognition is always easy. A word may be unfamiliar, a label too small, a translation unnatural or two choices too similar. Familiarity, vision, attention, literacy, language, assistive technology and context affect the result.

For a safety control, consequences matter too. Recognising its text does not reveal who receives it, whether location is included, whether a call starts or how to cancel. Put those facts where they are needed rather than relying on an explanation read weeks earlier.

What W3C guidance actually says

The W3C “Use Clear Visible Labels” pattern recommends common, understandable words, visible labels beside their controls and support for assistive technologies. It explains why missing or unclear labels can especially affect people with cognitive, memory or executive-function difficulties, and calls for user testing where the association is not immediate.

“Label in Name” connects visible text with the accessible name. If someone sees “Ask for help” but speech input knows the control by a different name, interaction may fail or surprise them. The visible words should therefore be included in the accessible name under the applicable criterion and techniques.

“Consistent Identification” and predictability guidance call for components with the same function to be identified consistently. Stability does not forbid improvement, but changing wording, colour, position and behaviour together makes prior learning harder to transfer.

A verification matrix for safety buttons

This matrix is neither a clinical score nor an accessibility certification. It turns the heuristic into observable questions before a routine depends on a control.

Visible labels and stable actions must remain honest

An effective label describes the action or outcome in words its audience uses. “Send SOS” is clearer than an unlabelled triangle, but may still omit who receives it. “Call emergency services” would be false on a control that only opens the dialler: visible promise and behaviour must match.

Stability means a recurring control keeps its name, relative position and consequence unless there is a reason to change. Colour and icon can reinforce the difference but should not be the only cue; colour vision, low vision, screens and cultural conventions make that fragile.

Confirmation may prevent accidental sends and show recipients, message and location. It also adds a step. There is no universally correct tap count: compare error risk, urgency, motor ability and cancellation, then measure with representative people.

Applying it to My Safe Circle, including its limits

My Safe Circle keeps SOS and ALL OK as separate free Home actions. SOS requires confirmation and a countdown. Message and location are optional, and location is added by explicit choice. The app may open the dialler but does not complete an emergency call.

“How are you?” requests show “I’m OK” and “I need help”. Replies are free; creating a manual request, which lasts 30 minutes, requires Premium. Creating or reactivating a recurring Reminder requires Premium and the recipient’s specific approval before it starts.

These labels expose choices but cannot ensure that every person recognises or operates them. My Safe Circle does not detect incidents or medical conditions, call emergency services automatically, or guarantee delivery, reading, understanding or action. A call, SMS or accessible command that suits someone better should remain in the plan.

Checklist: test the control, rather than merely showing it

A desk review finds obvious issues but cannot replace real use. Include people representing the intended languages, ages, abilities, devices and assistive technologies.

A recognisable interface is not an emergency service. With concrete immediate danger, use the most suitable channel and call local services. In the EU, 112 is common and free.
