Picture of Tom Erickson

The face that crashed a Japanese face recognition system (it assumed that hair lines are located over the eyes -- those cultural assumptions will get you every time!)


What made Wells a true visionary was not so much his ability to predict so many of the technological marvels of the late twentieth century, but his prescience in setting them in a world where men were still wearing neckties. --Geoffroy Nunberg

Sorry. I don't understand the word sorry. --Computer error message.

Press Enter to Exit. --Computer 'help' message

Plans are worthless, planning is invaluable. --Dwight Eisenhower

Q: So, has success changed you?
A: Yeah, it's changed me. You know how when you're eating pistachios and you find one that's hard to get the shell open? Well, I don't bother with them anymore. --Bob Weir

A few essays

You may be amused by part 2 of the story of my trip to Maui (The Key), or interested by my description of an area of Yoesemite that is recovering from a fire (After the Fire).

If you would like to stick your toe in more technical waters, you might like Ask Not for Whom the Cell Phone Tools (eventually published as Some Problems with the Notion of Context Aware Computing), a one page essay on cultural differences,[as pdf]and a poem on the state of theory in my field called Theory Theory, all of which have amusing bits.

In a more serious vein, you might be interested in reading about how telecommuting has impacted my life in Work and Spirit, On the Experience of Remote Meetings and, Some Notes on Telework.



Professionally, I’m interested in how people use technology to communicate and collaborate. I’m particularly curious about what they do to adapt technology to their needs, and how to design systems that are easier to learn, use, and adapt.

I retired in the Spring of 2018. I have no plans to work elsewhere or consult. I do plan to continue to pursue my professional interests, as well as exploring new areas. I am open to collaboration, and can be reached at a gif of my email address.

For more information about my profesional life, there is a one-page bio here, and a CV here. The publications page has links to nearly all of my papers, and farther down this page is an overview of the themes that interest me. A handful of my presentations can be found on slideshare.

For fun I read, write, run, bicycle, hike and garden.

Current Interests

Piano (and physical learning). I started learning the piano (starting from zero) in 2017. It is interesting (and humbling) to learn something with no prior foundations, and I find the learning process fascinating: Why do my hands find it easy to do some things (play in a mirror image), but difficult to do othes (play stacatto in one hand, and legatto in the other)?

Geology and other natural sciences. I've been taking courses in the natural sciences -- so far, Geology, Meteorology, Forest Ecology, Planetary Science, with Mineralogy and Chemistry next. My aim is to deepen my appreciation of the world in general, and particularly when I am out hiking.

My Work at IBM and Apple

Babble social visualization

Online Collaboration

Two themes pervade my work on online collaboration: persistence and visualization. The fact that online activity leaves traces that persist – meaning that they can be saved, searched, browsed, annotated and replayed – has radical implications for the future of online collaboration. I also believe that the ability of people to have convivial and productive online interaction is restricted by the lack of the cues that make our face to face conversation graceful and coherent. Much of my work has explored ways of using shared, minimalist visualizations (such as the one to the left) to give online participants a sense of who and how many are present, and what they're doing.

I've designed shared visualizations – which I refer to as social proxies –for chat, online meetings, auctions, queues, and other situtations. You can get a short overview here, or an in depth treatment here.

Cities, Crowds and Sustainable Design

The majority of the world's population now lives in cities, and their growth shows no signs of slowing. Both the pressures of continued immigration and the cumulative effects of unsustainable water, energy, and waste management policies create a vital need to address the problems of urban areas My current work at IBM is centered on "Smarter Cities." But whereas IBM's approach has to do with using sensors to gather information that allows urban systems to be analyzed and optimized, I'm interested in how to tap the local knowledge and expertise of urban inhabitants, and how to design systems that aid societies in shifting their collective behaviors – what I call "crowdshifting."

For a taste of this work, you can read a short essay on smart parking meters, or an academic paper on a city-scale project on using smart meters to give residents feedback on their resource use.

Personal Information Management

My earliest work in HCI – carried out mostly during my tenure at Apple – was focused on personal information management. I'm interested in how people create personal systems – piles, files, annotations, etc. – to support their own knowledge work, and how technology might support those personal systems.

I've recently had the humbling experience of re-reading some of my early papers. One from 1991 predicted that one day it would be possible for ordinary people to access as many as 10,000 databases via the internet, and was quite concerned with the difficulty of query languages. On the other hand, I think my 1996 paper on "social hypertext" was pretty much on the mark regarding the social nature of onine activity, although unfortunately I overlooked the rise of online advertising which drastically altered the social ecology of the web. A recap of this line of work can be found in my slideshare presentation on Personal Information Ecologies.

Methods, Frameworks and Theory

My chief interest is what is going on in the 'real world,' but to come to grips with that a variety of conceptual tools are needed. Among my longest running interests in this area is the concept of pattern languages – see my Lingua Francas paper. For over a decade I maintained a directory of work on patterns in HCI, although it is no longer current. I also have had a long term interest in the use of stories as a design tool – see this essay on storytelling – as well as scenarios and prototyping.

Although my work on Social Translucence has begun attracting attention a decade after its publication, I am ambivalent about the role of theory. I believe our field is too young for a grand overarching theory, but that more limited meso- frameworks and theories can be helpful as ways of enabling the discipline to take coherent approaches to particular problems and disciplines. I make this case in my essay Five Lenses for Interaction Design, and a bit more humorously in my poem, Theory Theory.
