Visual alerting tools are available to support the deaf and hard of hearing community. With strobe and flashing lights, smart lights, and vibrant visual digital displays, each tool is purposefully designed to grab attention, share important information, and boost overall awareness.
If you’re deaf and hard of hearing, you are probably already using or looking into a visual alerting device to help you be aware of things calling for your attention. In a world where sounds are often only used for communication, unfortunately, you often can’t respond to what you don’t hear in time, making life problematic and difficult.
As a person with hearing loss, you have terrific peripheral vision. We understand that this won’t apply to people who are deafblind, but studies have shown that people with hearing loss physically change their eyes to expand wider to see more things at the corner of their eyes. You unknowingly open your eyes to see more things and gain awareness of your environment. Without realizing it, your brain tries to adapt, and you can see much more than most people with hearing.
With a wide view, visual alerting devices for the deaf and hard of hearing are a great solution to many of the problems of a lack of awareness. There are three brackets of devices that you can benefit from using your solid peripheral vision. We’re here to help you know all of your options.
One thing to note is that visual alerting devices rarely act as stand-alone devices. Instead, they are usually part of a system that allows you to gather insights and send a signal to the visual component of the device.
Strobe or Flashing Lights
Lights blinking repetitively is one of the most common alerting techniques. They are often used in fire, smoke, carbon monoxide, or building evacuation alarms. In addition, lights that are known as strobe lights can be effective. Strobe lights are not easily portable and usually hardwired into the building. However, they work effectively to attract attention due to the extreme light intensity. But it is not as effective when people are sleeping.
Smartphone Camera Lights
Your camera flashlight can serve similar purposes. Many people with hearing loss like to use the camera lights on the back of their smartphones to alert them to app notifications. The only thing is that your screen will need to be facedown.
Smart Lights & light bulbs
Light Control with Plug-in Lamps
If it isn’t a strobe light, it could be a halogen or LED light that is available to be used. How they are used varies between visual alerting devices. One common way is to have an alerting system that controls the lights to attract your attention to an event. Sometimes, it gets your attention because the lamp is lit up by controlling the light bulb and other times, it’s a device with a built-in light that glows up in white or different colours.
Some visual alerting devices have a system that plugs into your electric outlet and uses your lamp to flicker the lights on and off.
Smart lights with a mobile app
With the trend of smart home technologies, smart lights are another way that you can get notified. Most smart lights have an app configured to turn on or off (or possibly flicker) based on specific rules. Some of the rules can connect with other smart devices in the home. For example, if you were hearing, you might be able to listen to footsteps without issue and be informed that someone is walking near your property. But for you, you rely on your smart motion detector. This detector may have advanced features that can connect to your smart light to turn on when someone is approaching your property.
Smart lights bring more technical capabilities, such as changing the light colour to attract your attention. For example, imagine your lights turning red and the room at night glowing in a non-white colour to alert you to an event.
Receiver with a glow
Some companies sell an alerting system that has multiple devices, including two major components called a transmitter and receiver. The transmitter does the job of knowing when to alert you to everyday household notifications, such as the doorbell, telephone ringing, or smoke alarms. The receiver takes command from the transmitter and displays or vibrates the information to you.
Some receivers have lights built into them. So that when the transmitter communicates information, it lights up and/or blinks on command.
Visual Display
Built-in displays
At times, devices have a built-in display with images that light; at times, it can be your smart device or smart TV that provides a visual display.
The challenge with having just a flashing light is that it tells you little about what is going on, other than that something has happened that needs your attention. A visual display that provides extra information can be found on some alerting devices. Another thing is that Light visibility is best when there is no known glare or natural light that powers the lights.
You may see symbols of baby cries, doors, or fire to let you know the exact purpose of the alert. You might even have screens with text outlining a message, like Notification alerts on your smartphone.
Smart TV display
Other times, more advanced visual displays are flat-screen TVs in public places or your home that are taken over from their usual programming or ads and replaced with important information, like warnings at the subway station or a broadcast emergency alert on your TV screen.
Visual notifications in visual alerting devices for the deaf have helped many people with hearing loss become aware of their environment when access to haptic or vibration alerts is not always possible or available in public spaces.
Lisnen’s app forms a bridge between the environment and senses that people like you need when it’s challenging to get the notifications that you need in the spaces that you are living in, be it temporarily or long-term.
