We will introduce evaluation criteria that can be utilized in the design and development of user-friendly device controls and components, easy-to-open containers, and child lock mechanisms.
【Classification of Items Used with Fingers】
There are many items in the world that are used with fingers, and the required "ease of use" varies accordingly. Therefore, we first classified "items used with fingers."
- Pressing with fingers, pushing up with fingers, pulling up with fingers, lifting with fingers, pinching with fingers (pulling, pushing, etc.), pressing and spreading open with fingers, grasping with hands (pulling, twisting, etc.), pressing with the palm of the hand.
For measurement items related to each action, related products, and the purpose of data usage, please refer to the attached materials.
【Measurement Items That Can Be Evaluated by Our Company】
Below are representative actions and their measurement items that can be evaluated by our company.
■ Pressing with fingers
(1) Operation interfaces of various devices (keyboards, mobile phones, operation parts of various devices)
- Subjective evaluation of ease of pressing, height and angle that can be used without strain, error operation rate.
(2) Child lock mechanism
- Force exerted, success and failure rates of unlocking.
■ Pushing up and pulling up with fingers (containers)
- Force required to open existing products, force exerted by a person, tolerance when opening daily.
■ Lifting with fingers
- Force required to open existing products, force exerted by a person, tolerance when opening daily.
■ Pinching with fingers and pulling (child lock mechanism)
- Force exerted (unlocking force).
