Issues Related to Physical Abilities and Movements

The following issues are related to users' physical abilities and movements. This section focuses on problems that all people, not just those with disabilities, may encounter in daily life.

Too high to reach

This problem affects people of shorter stature, children, wheelchair users, and seniors. Products must be designed so that all people can reach controls. It is important to design products to suit the usage environment and other conditions.

Too low to reach/unable to bend over

This problem affects people with lower back pain, pregnant women, and women wearing skirts. People do not like to squat. It is important to design products that do not force people to squat.

Able to use only one hand

Users may want to take photos while holding an umbrella. People also make copies at convenience stores while holding their wallet in one hand. It is important to make products so they can be operated with just one hand wherever possible.

Can't raise arms

This problem affects people with sore arms from stiff shoulders and people with arm injuries. It is difficult for anyone to lift heavy objects above the shoulders. It is important wherever possible to design products to be at the optimal height for use or to be light enough to lift easily.

Use a cane or crutches

Many people use canes to assist walking. Others use temporary crutches as they recover from sprains or fractures. Therefore, products must be designed so they can be carried and operated with one hand wherever possible.

Can't use fingertips/can't make fine movements

Photo opportunities occur even when your fingertips are numb due to the cold. Other people may have injured their fingertips or may have decorated their nails. Therefore, products must be designed with this in mind, such as avoiding layouts that are too tight and using buttons that can be pressed easily with long nails.

Fingers slip easily

Our fingers and hands slip more often than we normally think, such as dry fingers in winter or wet hands on rainy days. It is important to design products, such as cameras, that are held with our fingers so they can be held securely.

Can't move quickly / can't stand still

Many of us take photos while on holiday or from moving vehicles. It is impossible sometimes to make stable movements because of one's physical condition or the shooting conditions. Therefore, products must be designed with technical means that compensate for the user's circumstances or so that precise or quick operations are not needed.

Little physical strength

It is said that women generally have about 60 percent of the physical strength of men. Seniors and children often have even less physical strength. Products must be designed so that they can be operated easily with little physical exertion.

Can't enter or get close

When there is not enough room to move one's body, it is impossible to exert all of one's strength. Ample room is also needed for people who use crutches or wheelchairs. It is important that the designs of multifunctionals and other standalone products include sufficient space to operate the product.
