The contstructs of consumer computing devices

The computer and the internet are cultural artefacts that are part of our society, reflecting our values, belief systems and lifestyles.

Multitouch Interaction Design Space Boundaries (MIDS Boundaries)

There has been little formal study of social factors influencing HCI innovation, although has received limited attention by HCI researchers William Buxton, Paul Dourish and Lucy Suchman. These researchers have each commented on the issue of HCI innovation. Suchman researching the configurations of the “human-machine interface” writes, “tracing the differences within specific sociomaterial arrangements” is needed, but that “this requires expanding our unit of analysis, which the inevitable cuts or boundaries through which technological systems are constituted” (2007, loc. 2).

This research applies Suchman’s suggestion to a particular set of technological systems that is consumer multitouch devices, by focusing on three social factors influencing innovation in interaction design. This study employs the notion of design space as a conceptual frame. Design space is the totality of design choices available to the designer. The Interaction Design Space (IDS) takes the abstract ontology human computer interaction and applies physical characteristics to this ontology as to better understand it as a concrete terrain that can be measured and mapped. Thus here “interaction” refers to interaction with computing devices.

Multitouch Interaction Notation (MIDS notation)

There are limits to spoken and written language’s ability to describe interaction in any form. John McHale wrote,

… one of our major problems in thinking today is the use of language systems which still represent a fixed compartmentalized world view. The terms available to us for the expression of dynamic, rather than static, concepts are far from satisfactory (McHale, 1965 as cited by Friedman, 1997, p. 12).

MultiTouch Collaborative Work Station for Policy Analysts Group Project

Interface and MultiTouch Interaction Design Research—DRAGUN, a natural user interface (NUI) document browsing system for a multitouch table environments. DRAGUN is designed to enable researchers that are collaboratively authoring a report to navigate and annotate a collection of relevant documents. Our initial use case focuses on the work of Government Accountability Office (GAO) analyst teams who must gather, analyze, and annotate a large corpus of previously published GAO documents as they prepare a new report. Our test collection of documents is 81 GAO reports related to climate change. The system integrates machine-generated relationships, extant bibliographic metadata from the GAO, explicit user-defined relationships, and relationships inferred by observing user behavior.

Multitouch Wizardry—Timeline Interactive Multimedia Experience (T.I.M.E.) Group Project

ABSTRACT—As the 2009 Iranian election made clear, individuals use social networks to share information about important events and often they assign meaningful labels using tags. Users have an unprecedented ability to follow planned and unplanned events using social media and user-supplied content. However, this information is scattered across multiple systems and is not organized to promote a larger understanding of an event as a whole. Our system acquires and archives information from several different social networks using tags to identify events. Automatically collecting event information to be accessed at a multitouch information kiosk can address variety of information needs. With the T.I.M.E. interface users can access and interact with a corpus of social media about an event including following an event’s temporal progression.

One Butterfly Project—
Smithsonian Cross Catalog Search Interface

Currently, there are 1.7 million records in the catalog. Though the Smithsonian, like many cultural institutions, is building and refining its web presence, but they have yet to overcome the physical and technological barriers that separate their collections from the public.

In face Right now, the best way to experience the cultural objects is to visit Washington D.C.. The Smithsonian has the essential building blocks a bridge across physical and digital repositories for people to interact with media and ultimately culture.

I designed a suite of interfaces to access the records through a multitouch information kiosk.

(Above: a detailed view of a record)
