User-centered design evaluation helps to minimize the trial and error process that designers undergo by gathering the user’s feedback throughout the development process.
Currently, there are many design evaluation methods used to measure user attitudes toward designers’ concept and prototypes. With the application of these methods together with next level usability offerings, there is less risk of costly failures.
Eye-tracking studies are a type of usability test where user gaze concentrations are recorded in thermal-like "heat zone maps".
For certain usability studies, eye tracking usability data appears to be more valuable or empirical since it is recorded using technology and gaze capture instruments. Learn more.
Biofeedback studies capture conscious responses users make in evaluating designs.
During the capturing period, the users’ real time responses are filtered to designers through the communication process, which contains many inherent problems that are difficult to avoid, such as bias and misinterpretation.
Biofeedback has been used by psychologists for years and can provide objective results for website design evaluation.
Next level offerings of usability such as eye-tracking and bio-feedback can be carried out at any stage of product development.
Similarly maximum results can be attained by using more advanced and technical measurements of user’s behaviour from the conceptual stages right up to product launch.
