Is It Gropable?
Found in: Wearable Computers, IEEE International Symposium
By Nicholas Komor, Scott Gilliland, James Clawson, Manish Bhardwaj, Mayank Garg, Clint Zeagler, Thad Starner
Issue Date:September 2009
pp. 71-74
In a mobile environment, the visual attention a person can devote to a computer is often limited. In such situations, a manual interface should be “gropable,” that is, the user should be able to access and use the interface with little to no visual attenti...
Capturing Experiences Anytime, Anywhere
Found in: IEEE Pervasive Computing
By Daniel Ashbrook, Kent Lyons, James Clawson
Issue Date:April 2006
pp. 8-11
Anytime, anywhere experience capture is becoming the norm, especially capture involving multimedia. Digital cameras are ubiquitous and continually increasing in image quality. It's difficult to purchase a mobile phone that does not have a camera built in. ...
The Impacts of Limited Visual Feedback on Mobile Text Entry for the Twiddler and Mini-QWERTY Keyboards
Found in: Wearable Computers, IEEE International Symposium
By James Clawson, Kent Lyons, Thad Starner, Edward Clarkson
Issue Date:October 2005
pp. 170-177
<p>In a mobile environment, the amount of visual attention person can devote to a computer is often limited. In addition to typing rapidly and accurately, it is important to be able to enter text with limited visual feedback. Previously we found that...
Cancer navigation: opportunities and challenges for facilitating the breast cancer journey

By Elizabeth D. Mynatt, James Clawson, Maia Jacobs
Issue Date:February 2014
pp. 1467-1478
Cancer navigation programs help patients overcome emotional, financial, and logistical challenges not typically addressed by the medical system. In this paper, we provide a detailed description of a rural cancer navigation organization, specifically detail...
Don't mind me touching my wrist: a case study of interacting with on-body technology in public
Found in: Proceedings of the 17th annual international symposium on International symposium on wearable computers (ISWC '13)
By Clint Zeagler, Ellen Yi-Luen Do, Halley P. Profita, James Clawson, Jim Budd, Scott Gilliland, Thad Starner
Issue Date:September 2013
pp. 89-96
Wearable technology, specifically e-textiles, offers the potential for interacting with electronic devices in a whole new manner. However, some may find the operation of a system that employs non-traditional on-body interactions uncomfortable to perform in...
Grand challenges in text entry
Found in: CHI '13 Extended Abstracts on Human Factors in Computing Systems (CHI EA '13)
By Annalu Waller, Antti Oulasvirta, Benoît Martin, James Clawson, Keith Vertanen, Leah Findlater, Mark Dunlop, Per Ola Kristensson, Poika Isokoski, Stephen Brewster
Issue Date:April 2013
pp. 3315-3318
Our workshop serves two purposes. First, to bring text entry researchers working in the human-computer interaction (HCI), natural language processing (NLP) and augmentative and alternative communication (AAC) communities together at CHI. Second, we will se...
A study of cultural effects on mobile-collocated group photo sharing
Found in: Proceedings of the 16th ACM international conference on Supporting group work (GROUP '10)
By James Clawson, Namwook Kang, Nirmal J. Patel, SeungEok Choi, Thad Starner
Issue Date:November 2010
pp. 121-130
International and intercultural collaborations provide a unique opportunity to explore cultural differences in the usage and appropriation of a technology. Mobile photo capture and sharing has been growing in popularity in the Western world but nowhere has...
A model of two-thumb chording on a phone keypad
Found in: Proceedings of the 11th International Conference on Human-Computer Interaction with Mobile Devices and Services (MobileHCI '09)
By James Clawson, Nirmal Patel, Thad Starner
Issue Date:September 2009
pp. 1-4
When designing a text entry system for mobile phone keypads, a designer needs to overcome the ambiguity that arises from mapping the 26 letters of the roman alphabet to only 12 keys (0--9, *, #). In this paper, we present a novel two-thumb chording system ...
Mobiphos: a collocated-synchronous mobile photo sharing application
Found in: Proceedings of the 10th international conference on Human computer interaction with mobile devices and services (MobileHCI '08)
By Amy Voida, James Clawson, Kent Lyons, Nirmal Patel
Issue Date:September 2008
pp. 1-30
People use photographs for numerous reasons with one of the most common uses of both analog and digital photographs is as an artifact to share and discuss with others. While the practice of photo sharing has been thoroughly examined in the HCI community, t...
Automatic whiteout++: correcting mini-QWERTY typing errors using keypress timing
Found in: Proceeding of the twenty-sixth annual SIGCHI conference on Human factors in computing systems (CHI '08)
By Alex Rudnick, James Clawson, Kent Lyons, Robert A. Iannucci, Thad Starner
Issue Date:April 2008
pp. 49-54
By analyzing features of users' typing, Automatic Whiteout++ detects and corrects up to 32.37% of the errors made by typists while using a mini-QWERTY (RIM Blackberry style) keyboard. The system targets "off-by-one" errors where the user accidentally press...
