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

What is HCI?
•
•
Must know:
➡
The users
➡
The tasks
➡
The usage context
Should apply:
➡
Iterative user-centred design
➡
Usability principles
➡
Evaluation techniques

What is HCI?
HCI involves the design,
implementation and evaluation of
interactive systems in the context of
the user’s task.

What is HCI?
“If I were to sum up interaction
design in a sentence, I would say
that it’s about shaping our everyday
life through digital artifacts – for
work, for play, and for
entertainement.”
Gillian Crampton Smith, interview of
January 30, 2002

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.

HCI – Why?
• Have the user in mind
• Try it out
• Involve the users in the design process
• Iterate

Salvador Abreu
HCI – Why?
•
•
•
•
Systems must be robust and consistent.
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.
