Product Evaluation Techniques

Gathering opinions on a product through questionnaires with a rating scale, allowing users to elaborate on their answers.

Observing a user interacting with a product and recording their impressions, often with specified issues to focus on.

Methods for assessing how well a product performs in various aspects.

A survey used to ask questions related to product opinions with a structured format.

Aspects of a product that are assessed during evaluation (e.g., function, ergonomics, aesthetics, cost).

Presenting the results of a product evaluation, often using numerical ratings, to quickly compare performance against ideals or other products.

Designing products, systems, and environments to best fit human capabilities and limitations.

Incorporating human factors into design to ensure safety, comfort, and efficiency.

Using human body measurements (size, reach, weight) to design products for the majority of users.

The study of human body measurements, including size, reach, and weight, used in ergonomic design.

Considering age, sex, and race when selecting sizes for design elements to ensure user accessibility.

Understanding how the human body functions to minimize strain and promote comfort in product use.

Considering human perception, cognitive abilities, and emotional responses to design products for ease of use.

Ergonomics emerged relatively recently, building upon existing scientific fields like engineering, physiology, and psychology.

Ergonomics aims to maximize human productivity and well-being by ensuring technology and tasks fit human limitations and capabilities.

The primary human sciences used in ergonomics include anatomy, physiology, and psychology.

Ergonomics considers how visibility and lighting affect user experience and performance.

Ergonomics addresses how sound can inform users but also how excessive noise can be detrimental.

One key goal of ergonomics is to design jobs that are comfortable and efficient for people.

By focusing on human needs, ergonomics can improve efficiency, safety, and overall well-being in various tasks and environments.

A design approach that considers percentile ranges to cater to a majority of users, while acknowledging special cases requiring separate consideration.

The amount of force a user can exert in various positions when lifting, pulling, pushing, throwing, or jumping.

How long a user can perform a task or maintain a position before experiencing physical exhaustion.

The time it takes for a user to respond to a stimulus, such as pressing a button or braking a car.

The stresses placed on the body and its shape while sitting, standing, or holding objects in different positions.

The range of motions a user can make in different positions and their accuracy, considering the strains placed on the body while lifting, carrying, pulling, or pushing.

The practice of creating clear and understandable signs, symbols, and instructions, ensuring quick and safe comprehension.

Designers utilize various graphic techniques to communicate product information with different stakeholders at specific stages.

Quick, rough drafts of 2D and 3D designs with written notes, used for generating and exploring new ideas quickly in the early stages.

Detailed 3D drawings and sketches used to explore the form, proportion, and aesthetics of developing concepts.

Sketches and notes are used to generate and explore multiple design concepts rapidly.

Pictorial drawings are used to explore and evaluate the aesthetics of developing design concepts.

Designers use graphic techniques to communicate ideas to each other, ensuring everyone understands the vision.

Graphic techniques play a role in conveying information about the product to the general public.

Designing products that are accessible and usable by people of all ages and abilities, especially those who are older or have disabilities.

Designing products and services that cater to the specific needs and capabilities of an aging population.

A design philosophy that places the end user at the center of the design process, considering their needs, behaviors, and preferences.

The way in which humans interact with computers, including the design of software, hardware, and the overall user experience.

Industries with high risks, such as nuclear power, chemical plants, transportation (rail, sea, aviation), and air traffic control, are particularly vulnerable to the impact of human errors.

By considering the needs and limitations of users, ergonomic design improves efficiency, quality, and job satisfaction.

Designing for a diverse range of users, including those with disabilities and older individuals, ensures that products are accessible and inclusive.

High-quality 3D images used during the development stage to communicate product ideas to non-technical audiences. They provide a realistic view of how a product will look, helping clients visualize and evaluate design proposals.

Accurate 3D models created on computer programs. They are used to ensure components fit together during assembly and help evaluate product aesthetics.

3D models brought to life with movement and interaction. They are used to develop detailed designs and communicate with various audiences.

Presentation Graphics and Computer Models help explain complex concepts to clients without technical backgrounds.

Computer Models and Animations are used to convey information about products between design teams, manufacturers, and engineers.

Presentation Graphics are used to promote a product to potential clients and consumers, while Computer Models can help with visual marketing materials.

Computer Models can be used to create physical prototypes, allowing for early design testing and refinement.

Computer Models can help evaluate a product's ergonomics (how well it fits the human body) by enabling designers to test various positions and interactions.
