Both complete and correct?: multi-objective optimization of touchscreen keyboard
Xiaojun Bi, Tom Ouyang, Shumin Zhai
ACM Author-Izer service ACM Author-Izer Service
April 2014
CHI '14: Proceedings of the SIGCHI Conference on Human Factors in Computing Systems
Publisher: ACM
Full text available: PDFPDF (1.22 MB)
 Bibliometrics:  Downloads (6 Weeks): 31,   Downloads (12 Months): 169,   Citation Count: 1
Correcting erroneous input (i.e., correction) and completing a word based on partial input (i.e., completion) are two important "smart" capabilities of a modern intelligent touchscreen keyboard. However little is known whether these two capabilities ...

Bayesian touch: a statistical criterion of target selection with finger touch
Xiaojun Bi, Shumin Zhai
ACM Author-Izer service ACM Author-Izer Service
October 2013
UIST '13: Proceedings of the 26th annual ACM symposium on User interface software and technology
Publisher: ACM
Full text available: PDFPDF (784.59 KB)
 Bibliometrics:  Downloads (6 Weeks): 19,   Downloads (12 Months): 290,   Citation Count: 2
To improve the accuracy of target selection for finger touch, we conceptualize finger touch input as an uncertain process, and derive a statistical target selection criterion, Bayesian Touch Criterion, by combining the basic Bayes' rule of probability ...

Keywords: bayes' rule, finger touch, target selection

Octopus: evaluating touchscreen keyboard correction and recognition algorithms via
Xiaojun Bi, Shiri Azenkot, Kurt Partridge, Shumin Zhai
ACM Author-Izer service ACM Author-Izer Service
April 2013
CHI '13: Proceedings of the SIGCHI Conference on Human Factors in Computing Systems
Publisher: ACM
Full text available: PDFPDF (960.33 KB)
 Bibliometrics:  Downloads (6 Weeks): 11,   Downloads (12 Months): 145,   Citation Count: 1
The time and labor demanded by a typical laboratory-based keyboard evaluation are limiting resources for algorithmic adjustment and optimization. We propose Remulation, a complementary method for evaluating touchscreen keyboard correction and recognition ...

Keywords: simulation, text entry, touch screen interaction

Making touchscreen keyboards adaptive to keys, hand postures, and individuals: a hierarchical spatial backoff model approach
Ying Yin, Tom Yu Ouyang, Kurt Partridge, Shumin Zhai
ACM Author-Izer service ACM Author-Izer Service
April 2013
CHI '13: Proceedings of the SIGCHI Conference on Human Factors in Computing Systems
Publisher: ACM
Full text available: PDFPDF (705.13 KB)
 Bibliometrics:  Downloads (6 Weeks): 11,   Downloads (12 Months): 155,   Citation Count: 5
We propose a new approach for improving text entry accuracy on touchscreen keyboards by adapting the underlying spatial model to factors such as input hand postures, individuals, and target key positions. To combine these factors together, we introduce ...

Keywords: adaptive model, personalization, posture adaptation, touchscreen text input

FFitts law: modeling finger touch with fitts' law
Xiaojun Bi, Yang Li, Shumin Zhai
ACM Author-Izer service ACM Author-Izer Service

Fitts' law has proven to be a strong predictor of pointing performance under a wide range of conditions. However, it has been insufficient in modeling small-target acquisition with finger-touch based input on screens. We propose a dual-distribution ...

The impact of candidate display styles for Japanese and Chinese characters on input efficiency
Minghui Sun, Xiangshi Ren, Shumin Zhai, Feng Wang
March 2013
International Journal of Human-Computer Studies , Volume 71 Issue 3
Publisher: Academic Press, Inc.
 Bibliometrics:  Downloads (6 Weeks): n/a,   Downloads (12 Months): n/a,   Citation Count: 0
Entering non-alphabetic text for languages such as Japanese and Chinese into a computer typically consists of typing Roman character-based phonemes and selecting the intended Japanese or Chinese character from a list of homophonic candidates. This paper ...
