Alerts they can see,
not just hear

Choose the platform to see where its visual alerts live. Record the kind of flash, when it fires and whether sound recognition is on, mark each step, starting with whether flashing light is safe for the person, then note which real alerts they noticed.

Setups

The worked example is made up: a phone that flashes its camera light only when silenced, with sound recognition on, where game notifications drown out the class app, and a school laptop where a window flash is too small to notice. Use initials or a code, not names.

Teaching · Special EducationFree

What you finish with
A setup record per person and device: the visual alert, when it fires, sound recognition and how long notifications stay; eight steps marked done, to try or not needed, including a flashing light safety check; real alerts tried and whether they were noticed; and what to try next. The flags show where the setting lives on that platform and cautions about flashes, short notifications and relying on sound recognition. A large-print setup card prints for the device.
Who it is for
Teachers of the deaf and hard of hearing, special education teachers, assistive technology staff, families and students who are deaf or hard of hearing.
Format
Browser tool with a saved record per person and device. Prints a large-print setup card, the full record, every setup in a table or a blank form; downloads a spreadsheet (.csv); exports and imports a file.

A visual alert only helps if it is noticed and if there are few enough of them. Trimming notifications is half the setup.

Fewer, clearer alerts

Every app that can notify will. A flash for each game update trains the person to ignore flashes, so allow notifications only from messages, the class app, the calendar and anything safety related, and set those to stay on screen until dismissed.

Flashing light and safety

Most people are not affected by flashing light, but a small number have seizures that flashing can trigger. Ask the family or the school nurse before turning on screen or camera flashes. Sound recognition on a phone is a convenience; it does not replace a building’s visual fire alarm strobes.
