Ans) User-centered design (UCD) is an iterative design process in which designers focus on the users and their needs in each phase of the design process. In UCD, design teams involve users throughout the design process via a variety of research and design techniques, to create highly usable and accessible products for them.

- User-centered design (UCD) is an optimistic approach to invent new solutions. It starts with human beings and ends with the answers that are tailored to their individual needs. When you understand the people you are trying to reach, and then design from their perspective, you come up with unusual answers.

- Benefits of user-centred design
increase your sales - customers are more likely to buy a product or service that meets their needs. boost competitiveness - customers are less likely to choose other business' products if your product meets their needs more effectively.

- Keeping our focus on the tasks and users throughout the development process helped reduce the risk of designing an IHT application that was based entirely on what we considered important and useful rather than what the patient-users thought would assist with self-monitoring activities. We applied the principles of UCD, and employed a variety of usability-testing techniques to evaluate the effectiveness of screen designs, functions, navigation paths, labels, and other elements of the interface with representative users. Data from iterative testing informed modification and refinement of the application. When the prototype was deemed useful and functional in the laboratory setting, it was further tested in the field. As other studies have shown, involving users throughout the entire development process ensures that the final IHT is functional and acceptable as soon as it is ready to be deployed. We applied the principles of UCD to involve patient-users in the development of Pocket PATH, therefore increasing the likelihood of enhancing its success in promoting self-monitoring activities after lung transplant. Based on our results, applying UCD to the development of IHTs intended for use by other patient populations will assure that users’ needs and expectations are met.
