We assist in the creation of products (related to kitchens) in human and life engineering.

It is possible to evaluate and propose how to shape the sink and arrange the faucet for ease of use (such as reducing physical strain, etc.).

**Evaluation by Human and Life Engineering** ■ Evaluation Method We will prepare various specifications for evaluation targets and evaluators as shown below, and conduct evaluations according to the evaluation items. ■ Evaluators We can provide elderly individuals, young individuals, men, women, and people of varying heights. ■ Evaluation Targets The width of the sink and the position of the spout (adjustable according to the evaluator). ■ Targeted Rinsing Actions We plan to include five types of rinsing actions, such as rinsing small plates (for details, please refer to the basic information). ■ Evaluation Items (1) Subjective Evaluation We will conduct subjective evaluations regarding the following items: - Ease of rinsing actions - Perceived physical burden (shoulders, upper arms, forearms, torso, lower back, lower limbs) (2) Muscle Load We will measure the load (average muscle potential) on the following muscles: - 13 locations including the biceps (for details, please refer to the basic information). (3) Rinsing Actions We will measure the posture and movements of the evaluators using our developed markerless 3D motion measurement system (product name: Anakin). **Expected Outcomes** By examining the following items, we can understand how subjective evaluations differ and their relationship with muscle load, posture, and actions: ■ Width of the sink and position/height of the spout ■ Presence or absence of leaning against the kitchen.
