The combination of cognitive psychology and product design

For many product managers and designers, the design review PK as if the nightmare, the designer worked out the scheme, may be subject to many questions. Perhaps the scheme itself is excellent, but can not use theory to convince each other, the result is more ugly.

Since the birth of scientific psychology in the 1879, psychologists have carried out a lot of research on the laws of human cognition, emotion, memory and so on. Many conclusions can provide theoretical support for product design, and once again a brief summary of the sharing of Jane, please reader to enlighten you.

A software product first presented to the user is the product interface. Good interface elements are easy to recognize, easy to understand, fast to remember, and less error-prone.

1. Coding characteristics of interface elements

of identifiable

The earliest psychological pioneers, Fischna and Weber, were based on the threshold of sensory perception, and their research pointed out that human vision, hearing and so on can only be processed to stimulate the specific intensity range. In the process of interface design, attention should be paid to the recognition of elements. For example, the text can not be too small, color can not be too shallow.

of discrimination

The study of perceptual psychology shows that the perceptual ability of human beings has different threshold. The two stimuli must be greater than the differential threshold to be debated. Different interface elements (especially approximate, adjacent) visual characteristics should be able to distinguish clearly, to prevent users need to strive to identify, increase awareness of resources.

of significance

Stimulation must be meaningful and understandable. Therefore, the text expression, symbol icon design, should ensure that the user can understand correctly, no error.

Usability testing of the icon meaning: First test the user to see how high the rate of correct recognition;

After a period of time, the same user to test, to see the maintenance of the correct rate. o means original, R represents retest.

Standardization

Under different conditions, the meaning of stimulation needs to be unified. For example, every local red light means stop, and the green light means pass. For the same series of software, the icons and control styles of different platforms should also avoid conflict of meaning.

2. Compatibility of interface elements

Stimulus compatibility refers to the universality in different scenes and different situations. The better the compatibility of stimulation, the faster the speed of learning, the less reaction time, the fewer mistakes, the smaller the mental load.

Conceptual compatibility

For example, SOS, 110, 119, these abbreviations, conceptual compatibility are excellent. For example, red means stop, green means traffic and security, check use "tick" and so on.

Action compatibility

The spin value is associated with a numerical increase, such as a knob that adjusts the volume, and the pointer adjusts to indicate an increase in value, such as a thermometer scale.

In a mobile phone player, adjust the volume using the upper and lower keys, itself in line with the action compatibility, but the volume indicator for the left and right direction, the two mental model conflict.
