colour blindness or colour deficiency affects 1 in 12 men and 1 in 200 women worldwide. So how would I be able to have this be altred to them as well as all of the other disabilities? the first tip from this website was to combine the use of colour and symbols. the other was to keep it simple, this would also work for other groups of people.
Use textures to showcase the contrast between colours. The final two tips centered around choosing the right colour combinations if you have decided to use them. such as
- Green & Red
- Green & Brown
- Blue & Purple
- Green & Blue
- Light Green & Yellow
- Blue & Grey
- Green & Grey
- Green & Black
Braille
Braille is the surname of Louis Braille, he was a french blind scholar. he lost his sight in a childhood accident. he apparently invented a written language inspired by military crypto code when he was 15 years old at the Royal Institute for blind youth in 1824. The military crypto code was created by a French army captain Charles Barbier, he developed it so that soldiers could communicate without light. The braille system was initially developed for the french alphabet but was soon followed for English. The national braille press explains it as: “The braille cell is a unit of six raised or embossed dots—two horizontally and three vertically. Each dot in the cell is referenced by its placement numbers of dot 1 through dot 6. Various combinations of the six dots represent letters, numbers, and word contractions.” Braille design can only be read if it’s measured correctly to fit under the reader’s fingertips. “If cells are too small, too large, too close together or uneven in spacing, the message can’t be read properly,” says Frances Mary D’Andrea, chair of the Braille Authority of North America. “There is a standard size for each cell and standard distances between cells and even within a cell.”
So, no “font” sizes can be changed. According to National Braille Press, a standard braille page is 11 inches by 11.5 inches, and a 12-point document will essentially double in length with braille.
health statistics
According to the World Health Organization, "over 15 percent of adults over the age of 60 suffer from a mental disorder. A common mental disorder among seniors is depression, occurring in seven percent of the elderly population."
This could partly be because of the lack of accomplishment and not being able to do the things that you could want to do.
one out of three has a hearing impairment.

The proportion of people living with sight loss is:
one in nine people aged 60 years and over
one in five people aged 75 years and over
one in two people aged 90 years and over

things that affect older people on a daily basis. Typical daily activities (for example, how meals are prepared, what activities add meaning to life, and where problems may be occurring) and need for and availability of caregivers

a lot of this could be solved with heightened senses as they would not be as dependent on other people to do normal things.
Arthritis
one of the most common conditions for people over 65 years old is Arthritis according to geriatrician Marie Bernard, MD deputy director of the National Institute on Aging in Bethesda, Maryland. It is estimated that it affects 49.7% of adults over 65. It can lead to pain and a lowered quality of life.
Senses changes as you get older
HEARING
Your ears have two jobs. One is hearing and the other is maintaining balance. Hearing occurs after sound vibrations cross the eardrum to the inner ear. The vibrations are changed into nerve signals in the inner ear and are carried to the brain by the auditory nerve.
As you age, structures inside the ear start to change and their functions decline. Your ability to pick up sounds decreases. You may also have problems maintaining your balance as you sit, stand, and walk.SIGHT
As you age, the sharpness of your vision (visual acuity) gradually declines. The most common problem is difficulty focusing the eyes on close-up objects. This condition is called presbyopia. Reading glasses, bifocal glasses, or contact lenses can help correct presbyopia.
You may be less able to tolerate glare. For example, glare from a shiny floor in a sunlit room can make it difficult to get around indoors. You may have trouble adapting to darkness or bright light. Problems with glare, brightness, and darkness may make you give up driving at night.
As you age, it gets harder to tell blues from greens than it is to tell reds from yellows. Using warm contrasting colors (yellow, orange, and red) in your home can improve your ability to see. Keeping a red light on in darkened rooms, such as the hallway or bathroom, makes it easier to see than using a regular night light.
TASTE AND SMELL
The senses of taste and smell work together. Most tastes are linked with odors. The sense of smell begins at the nerve endings high in the lining of the nose.
Smell and taste play a role in food enjoyment and safety. A delicious meal or pleasant aroma can improve social interaction and enjoyment of life. Smell and taste also allow you to detect danger, such as spoiled food, gases, and smoke.
The number of taste buds decreases as you age. Each remaining taste bud also begins to shrink. Sensitivity to the five tastes often declines after age 60. In addition, your mouth produces less saliva as you age. This can cause dry mouth, which can affect your sense of taste.
Your sense of smell can also diminish, especially after age 70. This may be related to a loss of nerve endings and less mucus production in the nose. Mucus helps odors stay in the nose long enough to be detected by the nerve endings. It also helps clear odors from the nerve endings.
TOUCH, VIBRATION, AND PAIN
The sense of touch makes you aware of pain, temperature, pressure, vibration, and body position. Skin, muscles, tendons, joints, and internal organs have nerve endings (receptors) that detect these sensations. Some receptors give the brain information about the position and condition of internal organs. Though you may not be aware of this information, it helps to identify changes (for example, the pain of appendicitis).
Your brain interprets the type and amount of touch sensation. It also interprets the sensation as pleasant (such as being comfortably warm), unpleasant (such as being very hot), or neutral (such as being aware that you are touching something).
With aging, sensations may be reduced or changed. These changes can occur because of decreased blood flow to the nerve endings or to the spinal cord or brain. The spinal cord transmits nerve signals and the brain interprets these signals.
Health problems, such as a lack of certain nutrients, can also cause sensation changes. Brain surgery, problems in the brain, confusion, and nerve damage from injury or long-term (chronic) diseases such as diabetes can also result in sensation changes.
You may develop problems walking because of reduced ability to perceive where your body is in relation to the floor. This increases your risk of falling, a common problem for older people.
