Human Factors




Pro Engineer Portal is a California based product development firm specializing in human factors and we always design with the user in mind from the start.

When people communicate with one another, they communicate best when the dialogue is simple, easy to understand, direct and to the point. We assure device commands are easy to remember; error messages are clear, direct and not cluttered with computer jargon, and help messages are easy-to-understand and pointed.



In other words, people want a convenient, natural, flexible and easy-to-use system.

Product design human factors considerations




Human Factors definition

Human factors are defined as the application of scientific knowledge of human limitations, capabilities to design systems and equipment, and produce products with the most effective, safe, efficient, and reliable operation for individuals.


Safety is priority in the eyes of our design team

Although humans are capable of many highly technical, complex and intricate activities, they also have limitations to these activities. Of particular interest to a designer are limitations due to physical size, range of motion, visual perception, auditory perception and mental capabilities under stress.

Although a user may be challenged by these limitations, a designer cannot allow such constraints to adversely affect the safety, effectiveness or reliability of a device. Therefore, a designer should identify and address all possible points of interface between the user and the equipment being developed, characterize the operating environment and analyze the skill level of the intended user.


Prototypes designed with users expectations in mind

Concurrent design is a productive method of developing a final user interface design. This enables the thorough exploration of several design concepts before converging on a final solution. In the course of exploring alternative designs, limited prototypes should be built of the most promising concepts and user feedback obtained. This gets the users involved in the design process at its early stages and assures that the final design will be closely matched to users’ expectations.


Early industrial engineering studies

Human factors engineering, or ergonomics, can trace its roots to early industrial engineering studies of work efficiency and task performance using, for example, time-motion techniques.

One of our primary responsibilities to you, our clients, is to ensure you begin with a well-defined road map and a verifiable Smart Prototype prior to moving to the next phase.


Properly investigating a topic requires formulating a solid question.

Asking simple research questions is best, though you’ll nevertheless need a great deal of analysis to find the answer. Complex questions require complex answers; the degree of your question’s difficulty determines the analysis needed to find an answer. Strive to clearly see the question’s answer in your mind as you struggle to solve it, despite setbacks you encounter, until you have solid evidence to support your scrutiny. Remember: always treat the evidence discovered as a means to uncover the solution rather than as the solution itself.


The key to genuine research is a good question that addresses a problem calling for analysis. Without posing a question, nothing you are doing can be called research.
