Which factor is considered when designing ergonomic tools?

When designing ergonomic tools, comfort and ease of use are crucial factors. Ergonomics focuses on creating tools and environments that fit the user's needs, thereby enhancing efficiency and reducing the risk of discomfort or injury. An ergonomic tool is designed to accommodate the natural posture and movement of the human body, minimizing strain during use. This consideration leads to improved user satisfaction and productivity, as individuals can perform tasks more comfortably and with greater efficacy.

The other factors, though important in different contexts, do not prioritize the ergonomic principles of comfort and ease of use. While strength ensures a tool can effectively withstand the tasks it needs to perform, and durability ensures that it lasts over time, these qualities do not directly address how the user interacts with the tool. Cost-effectiveness is essential from a budgeting perspective but does not necessarily reflect how ergonomic a tool is or how well it suits the user’s physical characteristics and needs. Hence, comfort and ease of use remain the primary considerations in ergonomic design.
