Congratulations to former Informatics visiting scholar Mohan Singh and Informatics Faculty Member Donald J. Patterson on having their paper accepted to the IEEE International Symposium on Wearable Computers
‘Involuntary Gesture Recognition for Predicting Cerebral Palsy in High-Risk Infants’

Abstract:In this paper we describe a system that leverages accelerometers to recognize a particular involuntary gesture in babies that have been born preterm. These gestures, known as cramped-synchronized general movements, have been shown to be highly correlated with a diagnosis of Cerebral Palsy. In order to test our system we recorded data from 10 babies admitted to the newborn intensive care unit at the UCI Medical Center. We applied machine learning techniques to features based on their data and were able to obtain high accuracies on this cohort. Validated video observation annotations were utilized as ground truth. Finally, we conducted an analysis to understand the basis of the algorithmic predictions.

Congratulations Mohan, and Don!

Sensecam goes public for a mere $720.00 - May 28th, 2010

Sensecam

Sensecam

“Vicon Revue [http://www.viconrevue.com] is the commercial reincarnation of Microsoft’s Sensecam concept: a wearable digital camera that is designed to take photographs passively, without user intervention, while it is being worn. Its purpose is to support life-loggers wanting to track and document their everyday movements as digital memories. In combination with other physical sensors or additional image-recognition algorithms, the potential opportunities are enormous.”

Twitter, Sensors and UI: Robust Context Modeling for Interruption Management - March 2nd, 2010

Congratulations to Informatics Master’s Student Justin Tang and Informatics Faculty Member Don Patterson on having their paper,Twitter, Sensors and UI: Robust Context Modeling for Interruption Management accepted to UMAP 2010.

Abstract: In this paper, we present the results of a two-month field study of fifteen people using a software tool designed to model changes in a user’s availability. The software uses status update messages, as well as sensors, to detect changes in context. When changes are identified using a novel Kullback-Leibler Divergence algorithm, users are prompted to broadcast their current contexts to their social networks. The user interface method by which the alert is delivered is evaluated in order to minimize the impact on the user’s work flow. By carefully coupling both algorithms and user interfaces, interruptions made by the software tool can be made valuable to the user.

Congratulations Justin and Don!

FedEx has released a sensor board that is connected by mobile phone network and is designed to monitor sensitive cargo that would be harmed by environmental stress. It seems like a good gadget to know about if you ever want to track something globally without too much effort. $120/month

From the website copy:
SenseAware powered by FedEx
SenseAware can monitor items that are:

  • Unique or rare — such as samples from clinical trials.
  • Temperature sensitive — such as pharmaceuticals.
  • Light sensitive — such as film or art
  • Time critical or location critical — such as human tissue and organs.
  • Highly controlled or regulated — such as materials requiring chain-of-custody certification.
  • Biohazardous or dangerous — such as explosives.
  • Highly valuable — such as medical equipment.

Wireless Detectors for Dementia - February 2nd, 2009

A little love from the article her: Technology Review: Wireless Detectors for Dementia

“Researchers hope that radio transmitters can warn of cognitive decline earlier.”

“Donald Patterson, a professor of informatics at the University of California, Irvine, says that the USF approach is more straightforward that those designed to monitor complex activities. “The more you get into the straight biological measurements . . . the easier it becomes,” he says.”

Dashboard U/I Innovation - May 1st, 2008

Lamborghini Reventón Dashboard

The dashboard for the Lamborghini Reventón. How much does good design cost? Well this design will cost you 1 million euro. Oh for the day when my car needs an artificial horizon indicator….

Bruce Sterling

Bruce Sterling gave the opening keynote at UBICOMP 2006 on 9/17/2006 entitled, “Spime Meme Map”. It was video-captured and edited for the public and is distributed here. The introduction is made by Crista Lopes, and Paul Dourish faculty at UCI Department of Informatics, and Adrian Friday faculty at the University of Lancaster. Bruce begins speaking at 00:10:20. The talk is enclosed in the RSS feed, or click on here.

Major credit is due to Jeff Hughes of Intel Research Seattle/ University of Washington, etc. who burned many cycles putting this together. Thanks Jeff!

Project Ladybag - June 9th, 2006

Project Ladybag has a built-in LED display that reacts to the user’s behavior in two ways. In this image the bag is shown reflecting the user’s emotional state through the display of emoticons. Emotional state is determined through explicit interactions with the bag that are registered through physical sensors.

The second mode of behavior is through an RFID reader in the bag. In this mode, the bag displays cues on the exterior of the bag when expected items (tagged with an RFID) are missing. Forget your keys, then your handbag will know.

Does this design make sense? What do you think?
