Xerox Star

4

•  1970 - Alan Kay Xerox PARC - laptop computer for ordinary users (Dynabook)

•  1973 - Alto desktop computer with mouse, Ethernet & overlapping window display.

•  not easy to use & lacked a killer app •  1976 - Don Massaro XEROX - personal

computer for office environments (Star) •  clean & consistent - right-button menus,

controls & embeddable objects •  best-practices document •  design before any code was written •  code – in small steps with user testing •  failed in the marketplace, but Macintosh

was a huge success


Features of the Xerox Star

§  Desktop metaphor § Mouse §  Right-‐buYon menus §  Controls §  Embeddable objects §  Trash bin §  ….

Lessons from the Xerox Star design §  Good mass-‐centred design requires a user-‐centred approach

§ When you execute a user-‐centred design well, you get a design that endures for decades

§  Good HCI design is evolu0onary rather than revolu0onary – “Good ar0sts borrow; great ar0sts steal” (Picasso)

§  Crea0ve HCI design is technology driven combined with principles of human behavior

TRENDS IN HCI TECHNOLOGY

11


Context-‐awareness

§  Loca0on services – GPS – RFID, NFC

§  Environment services – Light – Weather – Movement

12


Percep0on: image analysis §  Facial recogni0on §  Emo0on detec0on (Mona Lisa example)

13

In 2005, UvA and Universtiy of Illinois experiment with “emotion recognition” software è Mona Lisa was 83% happy, 9% disgusted, 6% fearful, 2% angry, less than 1% neutral, and not at all surprised

Google’s Project Soli


From GUIs to NUI


Percep0on: speech technology

§  Failed in the “office segng” §  New possibili0es in the “mobile” & “medical” segng

§  Is improving constantly – Mul0ple languages –  Large vocabularies –  Compu0ng power

§  Success examples –  Siri, OK Google, Speech input for mobile devices

18


From fixed displays to smart fabrics

§  Many more surfaces used for interfacing

§  Example: fabrics, walls

Social robot interfaces

§  Robots as social companions

§  Use advanced learning techniques

§  HCI challenge

TRENDS IN INTERACTION

29


THE END OF INTERFACE STABILITY

30


Ques0ons for HCI

§  How will we know what computa(onal resources are available within us and how these will interact with resources around us?

§ What interac0on techniques are appropriate if embedded devices have no explicit or recognizable interface?

§ Will more in0mate devices mean old concepts of ‘the interface’ become obsolete and irrelevant in the future?

31


The growth of techno-‐dependency §  New fireman oumit with sensors and trackers

§  The more we depend on technologies to carry out or mediate our everyday ac0vi0es, the more we will need to trust them to do so’

32


Ques0ons for HCI

§ Will there be ever-‐increasing expecta0ons for be9er and faster technologies?

§  How might the technologies in 2020 alter the skill-‐sets and understandings of future genera0ons?

§  How do we design technologies to help people cope when the infrastructures break down, devices malfunc(on or get lost?

33


The growth of hyper-‐connec0vity

§  How can technology help us manage our availability to others?

§  What new codes of e(que9e will come into play?

§  How can new communica(on technologies be designed to know who people are really?

34


The growth of crea0ve engagement

35

§  How can the interac(on & design of new computa0onal tools be structured so they do not impede crea(ve engagement?

§  What new toolkits can be developed to enable scien(sts, and others to create tools for themselves to solve their own problems and explore new avenues?


New forms of learning

36


Ques0ons for HCI

§ What kind of interac(ons work on the Web? § What needs to be done person-‐to-‐person? §  How should interac(on in a Web lecture be organized? – Should you be able to see the lecturer? –  Interac0on forms with teachers, fellow students

The ‘value’ of augmen0ng human memory

§  In what situa0ons might we want to remember and why?

§ And is it some0mes beYer and more desirable to forget?
