Auditory and projection clocks can be used by people who are blind or have limited vision. There are also clocks for the blind that have displays that can be read by using the sense of touch. Some of these are similar to normal analog displays, but are constructed so the hands can be felt without damaging them. Another type is essentially digital, and uses devices that use a code such as Braille to show the digits so that they can be felt with the fingertips.
Similar to our #8 selection, this app uses a gradual brightness increase to slowly wake you out of your sleep, before laying down the hammer and buzzing to wake you up. If you’re waking up angry or abruptly (more on this in a moment), then this is the perfect trick to keep ahead. Just ensure your alarm clock also has a USB charging slot to keep your phone nearby. This works well if you position it differently than your gradual light alarm clock, as if you’re getting two sunrises instead of one.
A clock mechanism may be used to control a device according to time, e.g. a central heating system, a VCR, or a time bomb (see: digital counter). Such mechanisms are usually called timers. Clock mechanisms are also used to drive devices such as solar trackers and astronomical telescopes, which have to turn at accurately controlled speeds to counteract the rotation of the Earth.

Clocks aren't just for telling time! Take this one for example: artful with its understated analog dial, this piece is perfect lending an upscale feel to your living room look or kitchen ensemble. Measuring 16'' circular, its frame features a glass design accented by a shiny chrome center and openwork hands to mark the hour. This product required one AA battery to operate, which is not included. Suitable for indoor use only.
“I bought this light because my partner and I need to be up early for work, but our bedroom has very poor natural light. Within a week, I’ve already noticed a difference in my energy levels and mood. The sunrise simulation works perfectly; by the time the ‘alarm’ (peaceful bird noises) goes off, I’m already feeling naturally awake — not groggy or jolted out of my sleep. I feel much more rested, and my average resting heart rate reflects that. I also really love the sunset feature. I wasn’t expecting to get much use out of it, but I feel like it does a great job of helping me settle into bed at the end of the day.”
