How to make your iPhone LED flash for calls and notifications

March 23, 2022 6:46 am

Using Apple’s Accessibility feature, it’s possible to make the iPhone’s LED blink when there’s an alert, such as an incoming call or a text message.

The LED is beside the rear camera and is the same flash that’s used for photography. When the LED flashes for an alert, it doesn’t use the full intensity as it does when taking a photo in a dark room. Instead, a toned down, gentle blink that’s noticeable without being blindingly bright is provided.

To switch this feature on, the user should open the Settings app, scroll down and select Accessibility, then find the ‘Audio/Visual’ options and open those controls. At the bottom, there will be a toggle switch labeled ‘LED Flash for Alerts.’ Switching this on will tell the iPhone to blink the LED when an alert is received.

Once ‘LED Flash for Alerts’ is enabled, another option is revealed below which is on by default. Toggling the ‘Flash on Silent’ switch to the off position will prevent the LED from flashing when the physical mute switch on the left side of an iPhone is set to silent. In this position, a red stripe can be seen inside the switch. When enabled, the rear LED will blink for every notification, call, and text, regardless of the position of the iPhone’s mute switch.

There are a few different situations when this feature might prove useful. For those with a hearing impairment, the flashing LED makes it easier to notice a call or message when not looking directly at the iPhone. For others, it’s a way to potentially make the iPhone less obtrusive while having a conversation. With the iPhone face down and volume muted, an LED blink can be a nicer way to know that an alert has arrived without the usual notification chime, making this a helpful feature for everyone.

Using a Haptic Device, Blind People Can See Microscope Images:

A team at Purdue University in Indiana has developed a haptic device that lets blind people feel images generated by a microscope. It has always been a huge undertaking to help the blind understand microscopic images. Sometimes, a sighted person just must describe it, which is problematic sense each description differs, and the blind person can’t always understand the description. Also, tactile images can be created and labelled in braille, but this is labor intensive and requires a sighted individual with the knowledge, time, and skill to do it.
This new device is a haptic feedback joystick that plugs into a computer that also has a microscope connected to it. It has been tested on red and white blood cells. The blind person navigates the cell with the joystick, and receives a pushback when encountering a cell wall, and different vibrations when hovering over different textured objects.
So far, tests have indicated that a blind person can identify the difference between a white and red blood cell more accurately using this device than by means of other methods.

Handheld Scanner Converts Text to 36Cell Refreshable Braille: Cost, About $100:

Six women, all undergraduate engineering students at MIT, won last year’s MakeMIT Hackathon by creating a device that can easily change the world for people who are blind.
They call themselves Team-Tactile, and they did something that should have been done a long time ago.
They created a device that is the size of a candy bar. It has a camera on the back, it runs OCR software, and it has 36cells of refreshable braille on the front. You just move the device, for now called Tactile, over printed text, and it is immediately displayed in braille on the front. Think about what an improvement this is over current methods of taking pictures, waiting for OCR software to convert to text, and then having to have a very expensive braille device connected to whatever you used to take the picture and convert to text.
The team only had 15 hours to create this device during the hackathon competition, and it only costs around one hundred dollars.
The problem in the braille display market is that no one has been motivated to create anything new and affordable. We are still using technology that is decades old, and the cost for these devices are in the thousands of dollars. It is about time that new options come to those who desperately need it. Only 10% of blind people can read braille, 70% of blind people are unemployed, and 80% of blind people who are employed can read braille. You do the math. Having easy access to braille material directly correlates to a more educated and productive blind community.

The New ChromeVox Screen Reader for Blind Users of Chrome Books is Now Ready:

All Chromebooks released in 2017 will have the ability to run Android apps, some of the new Chromebooks have greatly improved specs, and now Google is also making improvements to its ChromeVox screen reader. Maybe it’s time to stop and take a serious look at Chromebooks again.

Here’s what’s new in ChromeVox:

We’ve made big changes to the Chrome OS screen reader known as “ChromeVox.” ChromeVox comes built-in with every Chromebook, and These changes are the result of important feedback from our ChromeVox users (and other lessons learned over the years). For now, the older version, now called “ChromeVox Classic” (“Classic” for short), will still be available, but because we’re so sure you’ll like this new experience, it won’t be for too long.

What’s changed

• The ChromeVox modifier key combo is now just the Search key .
• Easier jump commands, like pressing Search+H to jump to the next heading or Shift+Search+H to move back.
• Sticky keys work across the entire Chrome OS screen, including the shelf and status tray.
• Other commands also work everywhere, like Jump commands and ‘find in page’.
• A new caption panel displays speech and Braille output at the top of the screen.
• New menus list all the ChromeVox keyboard commands. (Press Search + Period.)
• New sounds (‘earcons’) identify key parts of the screen, page load progress, and more.

If you have a watch with a speaker, and you are running Android Wear 2.0, you can enable TalkBack by powering on the watch while holding two fingers on the screen of your watch. This is the same way you enable TalkBack on your phone. Currently, the new LG Sport and LG Style watches from LG and Google come already running Android Wear 2.0, but you will need to see if the watch you are purchasing comes with Android Wear 2.0, or can be upgraded to the new operating system.
