CHASR supports user interface design and interaction design, and we have developed a number of custom applications for our researchers and clients over the years. We will work closely with you to understand your needs, and apply an iterative design approach, and involve you throughout the design process. We are experienced with a variety of design techniques, including contextual design, user interviews, and rapid paper prototyping, and we are also knowledgeable about design principles, such as Jakob Nielsen's usability heuristics and Don Norman’s design concepts. We use both when developing new interactive software.

CHASR has the experience and expertise to capably carry out usability testing for our researchers and clients, and we have produced reports summarizing our findings. Usability testing is commonly used to find problems or gaps in an application’s user interface and interaction design. Testing involves recruiting participants to represent the target audience. Participants are asked to carry out common tasks using the software, while an observer takes notes on problems encountered in completing the tasks. Participants are also given an opportunity provide additional feedback after each testing session through custom surveys or questionnaires.

We are experienced at carrying out expert usability reviews, used to supplement design or testing activities. Expert reviews are carried out by knowledgeable evaluators, and sessions follow a structured methodology that help to find usability problems. Common methods include heuristic evaluation and cognitive walkthrough.
