Physical Ergonomics Control Devices

Which of the following is NOT a typical input mechanism for control components?

Controls are always easily accessible and visible.

What is one requirement of user operation in ergonomics?

A __________ is a device that translates a movement into an internal command.

Match the following types of controls with their movement type:

Regarding ergonomic requirements, which aspect influences how easily a control can be reached?

Discrete and continuous changes refer to different types of movement options for controls.

Name one type of control that involves a sliding motion.

Which of the following is not a step in the design flow?

User observation is a crucial part of the design process.

Name one way a control component conveys command transfer.

The dimension of control used for selecting functionality is referred to as __________.

Match the following design steps with their descriptions:

Which of the following actions is associated with the 'during' phase of control usage?

In the design process, all users should undergo the same testing protocols.

List one of the features included in the preliminary requirements.

Ergonomics: Physical Ergonomics

Control Devices: A control is an input mechanism for a device. It's usually a standard part on the exterior for easy access, needing simple movements to initiate an action. This transforms into inner commands, modifying functions as needed.
Control Placement Variations: Controls aren't always fixed in place: some are remote (like a remote control); others may be strategically hidden for a specific reason, or have complex operation mechanisms.

Ergonomic Control Types

Patterns: There are patterns in how controls are used for tools or machines. Input begins with user interaction. Initial contact with the control, followed by adjustments using force and/or movement for positioning.
Input Mechanisms (Many Types): These include, but aren't limited to, mechanical (most common in many devices), pneumatic, optical, electrical inductive, and auditory (like voice control).
Physical Action: Control actions involve single or repeated movements (one-time or continuous); movements can also be discrete (on/off) or continuous (e.g., adjusting intensity).

Additional Control Requirements

Action Characteristics: Actions can be: pressing, pulling, sliding, rotating, or a combination. Control actions need to consider the amount of force needed, and the precision required for the task. Qualitative and/or quantitative specifications are necessary.
Control Design Considerations: Design must consider the form factor (shape, size, and aesthetic design) and appropriate locations (where users expect to find the controls) along with the user's anthropometric fit, to allow for comfortable and useful usage. Feedback, like tactile sensations, can help the user to ensure correctness of operation.
