Overview

• General Impressions• Workshops• Opening Plenary by Judy Olson• Highlights of Technical Track

– Video Showcase– PARC papers– Interesting papers

• Closing Plenary• Lab Visits to Google/MS/IBM/MIT


General Impression

• Lots of students looking for jobs– Too much specialization, too narrow

– Too many iSchools and HCI departments generating students focused on user studies and interaction design

• Academia looking forward to increased funding– NSF and NIH seem both active


General Impressions

• HCI strong institutions are – First tier: CMU, Microsoft, MIT, IBM,

UW, GaTech

– Second tier: Cornell , Penn State, Stanford, UCBerkeley

• Google, Facebook, Yahoo are all largely missing

• Industry Research Lab reasonably strong, but much more dispersed– General nervousness about the

future of the economy and industrial research


Workshops

• Sensemaking workshop• Social Mediating

Technologies: Developing the Research Agenda

• Interacting with Temporal Data


Sensemaking Tools

Broadly, issues facing toolmakers can be deal with in four large pieces:

• SM Phases• SM Context• SM Scale• SM Requirements

72009-05-06 CHI2009 Trip Report

Top Ten Requirements for SM tools

1. Keeping track of progress / alternatives, provide useful advisement; hypothesis generation; Facilitate refining and shifting – [Data State Model?]

2. stimulate diversity -- Conflict and multiple POV (diversity) management - Balance

3. Help with narratives and deal with confirmation bias4. Carry rationale / provenance, integrated communication5. Data and project management are critical6. Enable building up of synergy between individual and group

sensemaking7. Keep track of confidence in the analysis: Provide trust and

evidences of consensus8. Analyze / Reduce risk of handoff9. Readiness of revisit: Undo / history, readwear and editwear

for state of sensemaking10. Transparency and explanation of the state of the model

Closing Plenary -- Kees Overbeeke

• Always someone outside the community, often with a design bent.

• “Dreaming of the Impossible” focused on a European perspective on design and technology.– Design is about people. It is about our lives, our hopes

and dreams, our loneliness and joy, our sense of beauty and justice, about the social and the good. It is about being in the world.

– a primacy of action. In accordance with some theories of knowledge, meaning cannot be detached from action. Meaning is in (inter)action. There is a primacy of embodiment.


Kees Overbeeke

– A design theory consequently must be a theory of action and the embodiment in the first place, and of meaning in the second, and not the other way around. Reflection on action is the source of knowledge.

– The methods used must be rooted in design practice, in the socio-cultural environment, invigorated by experimental and technological methods from other disciplines.

– Intuition and common sense should be high on the agenda. They should be exploited to the maximum.


Some neat things
