Interfaces Pessoa Máquina 2010/11 ©2009-11 Salvador Abreu baseado em material ©Alan Dix 8 Wednesday, May 25, 2011 What is HCI? • Factories in the beginning of the XX century – human performance evaluation in manual tasks. • World War II – production of more effective weapons. • Formation of the Ergonomics Research Society, 1949. • Man-Machine Interaction => HCI • The study of Human-Computer Interaction involves several aspects: – Physical – Psychological – Theoretical Interfaces Pessoa Máquina - 2010/11 Wednesday, May 25, 2011 9 Salvador Abreu What is HCI? • • Must know: ➡ The users ➡ The tasks ➡ The usage context Should apply: ➡ Iterative user-centred design ➡ Usability principles ➡ Evaluation techniques Interfaces Pessoa Máquina - 2010/11 Wednesday, May 25, 2011 10 Salvador Abreu What is HCI? HCI involves the design, implementation and evaluation of interactive systems in the context of the user’s task.

Interfaces Pessoa Máquina - 2010/11 Wednesday, May 25, 2011 14 Salvador Abreu HCI – Why? The world's atomic energy authorities have been on alert since reports surfaced linking the deaths of eight patients undergoing treatment for pelvic cancer at the National Oncology Institute in Panama City, Panama, to overexposure during radiation therapy. The International Atomic Energy Association (IAEA), Vienna, Austria, which has been investigating the deaths, said the overdoses probably were not due to a malfunction of the radiotherapy machine, but to a problem with the system's data entry method. In August 2000, the Oncology Institute changed the process for entering coordinates for "shielding blocks" designed to protect healthy tissue during radiation therapy. The IAEA report said the change, coupled with a lack of updated written standard procedures, resulted in miscalculations of radiation intensity and treatment times.

Must be prepared for the target users. Must deal with careless usage. Should be helpful => help in completing a task instead of creating extra obstacles. • Interface design shouldn’t be handled only at the last minute. ➡ Interfaces must be developed along with the rest of the system.
