Advances in digital technologies have enhanced the capabilities of surgical practitioners in significant ways. With each advance, the relationship between human operators and digital assistants becomes ever more inter-dependent and intertwined. Tim worked closely with product developers and surgical practitioners to understand the opportunities for enhancing the patient and surgeon experience. Through in-theatre observations during operations and interviews with surgeons, radiographers and support staff, he used principles of user-centred design to optimise the overlay and data visualisation system in the context of the operating theatre. Join us for a session that discusses how we can apply solid experience design methods in new environments by learning new nomenclatures, taxonomies and relationships to make sense of human interactions in extraordinary contexts.
