Steven C. Seow joined Microsoft Corporation as a Usability Engineer after completing his Master’s Degree and Ph.D. in Experimental Psychology at Brown University with a research focus on human timing. Prior to Brown, the Singapore native completed his Bachelor’s and Master’s Degrees in Forensic Psychology at John Jay College of Criminal Justice with a thesis examining the distortion of time perception in ‘earwitnesses’. While completing his doctorate, he published his first theoretical paper in the Human-Computer Interaction Journal that compares two information theoretic models of human performance. Steve is currently a user researcher with the Surface Computing at Microsoft, and frequently confers with other colleagues across the company to talk about time and timing issues. Coupled with his scholarly interest in psychology is his passion for computer technology. On his spare time, Steve enjoys tinkering with computer hardware, dabbling with programming languages, and building websites. He lives in Maple Valley, WA, with his wife and son.

“Natural user interfaces (NUI) such as multitouch and surface computing are positioned as the next major evolution in computing and user interfaces. Just graphical user interfaces (GUIs) brought unprecedented interaction capabilities to their command-line predecessors, we believe multitouch and surface computing will spawn novel ways to interact with media and improve social usage patterns. Since experimentation and deployment are currently limited, the exploration of applications and interfaces in this area is still at an early stage.”

Seow, Steven C. (2005): Information Theoretic Models of HCI: A Comparison of the Hick-Hyman Law and Fitts' Law. In Human-Computer Interaction, 20 (3) pp. 315-352

“The Hick-Hyman Law and Fitts' Law are two surviving human performance principles based on Shannon and Weaver's (1949) Information Theory. In the early 1980s, Card, Moran, and Newell (1983) presented the laws as design principles for developers to maximize usability in the design of human-computer interfaces. A search of the current human-computer interaction (HCI) literature, however, will reveal that the Hick-Hyman Law failed to gain momentum in the field of HCI, whereas Fitts' Law received, and continues to receive, substantial attention. This article begins with a discussion the common information theoretical concepts of the two laws, and then examines each law with respect to its origins, theoretical formulation, theoretical development, research, and applications and examines the possible contributing factors responsible for the failure of Hick-Hyman Law to gain momentum in the field.”

Seow, Steven C. (2005): The effect of subdivision of intervals in continuation tapping. In: NEST March 5, 2005, 2005, New Haven, CT. . Available online

“It is natural for people to subdivide an isochronous interstimulus interval (ISI) to better remember and reproduce the interval. For example, an ISI of 1000 ms can be mentally subdivided into four subintervals of 250 ms, and a response can be produced at every fourth subinterval. Three experiments were conducted to assess the effects of subdivision on a self-paced continuation tapping performance. In all experiments, participants listened to isochronous metronome-like auditory stimuli (loud ticks) that were separated by a less accented version of the stimuli (soft ticks). When the presentation of these stimuli was completed, participants proceeded to tap on a key to the interval established by the loud ticks. Analysis of the interresponse intervals (IRIs) from the three experiments showed that self-paced continuation tapping was closest to the ISI when length of the subdivision was 400 ms. These results support prior findings of a privileged point between 300 and 400 ms that leads to optimal motor performance in finger tapping. ”

Seow, Steven C. and Church, Russell M. (2003): Determinants of Drift in Continuation Timing. In: NEST March 15, 2003, 2003, New Haven, CT. . Available online

“In a standard continuation timing task, participants are instructed to tap a key in synchrony with an isochronous auditory stimulus sequence (synchronization phase), and then to continue tapping at the same rate after the sequence is halted (continuation phase). During the continuation phase, a frequent finding is that the (onset-to-onset) interresponse intervals (IRIs) tend to drift, but these drifts are more likely to be statistically eliminated than explained by researchers. The present experiments focused on systematic drifts and their relationship to the (onset-to-onset) interstimulus interval (ISI), which varied from 200 to 800 ms, under several experimental conditions. The conditions included a standard continuation task (Standard), a task in which the participants did not tap during the synchronization phase (Listen), and a condition in which there was an 8-s delay between the synchronization and continuation phase (Delay). Under all conditions, there was a linear relationship between the residual IRI (IRI-ISI) and the ordinal position of the taps during the continuation phase. Under the Standard and Listen conditions the intercepts and the slopes were negatively related to the ISI; under the Delay condition the intercepts were negatively related to the ISI, but the slopes were negligible. These systematic drifts, and the differential effect of an 8-s delay between the synchronization and continuation phases, provide the basis for new interpretations of the processes involved in continuation tapping.”
