kinectable_pipe - July 6th, 2012

kinectable_pipe is a command-line utility that dumps user skeleton data from a Microsoft Kinect device to a standard Unix pipe.

Why?

Because Kinect programming is a pain in the neck, and by trivializing the device’s output into a simple text format, it becomes infinitely easier to digest in the scripting language of your choice.

This seems simple to the point of being almost useless

Yes, that’s the point. Do One Thing and Do It Well. There’s an accompanying rubygem that will add all the smart stuff like advanced gesture recognition, events, etc.

I tried it. It worked:

  • Time 0:00 ran down to lab to grab Kinect
  • Time 1:40 Kinect plugged into Mac
  • Time 6:00 Software installed
  • Time 7:00 Path problem fixed
  • Time 9:30 Data being collected
  • Time 30:00 Data formatted and posted

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!

AAAI 2009 Spring Symposium on Human Behavior Modeling - August 5th, 2008

AAAI logo

“The AAAI 2009 Spring Symposium on Human Behavior Modeling will explore methods for creating models of individual and group behavior from data.
Models include generative and discriminative statistical models, relational models, and social network models
Data includes low-level sensor data (GPS, RFID, accelerometers, physiological measures, etc.), video, speech, and text
Behaviors include high-level descriptions of purposeful and meaningful activity or abstractions of cognitive and affective states. These include activities of daily living (e.g., preparing a meal), interaction between small sets of individuals (e.g., having a conversation), mass behavior of groups (e.g. the flow of traffic in a city) and related internal user states.

While behavior modeling is part of many research communities, such as intelligent user interfaces, machine vision, smart homes for aging in place, discourse understanding, social network analysis, and others, this workshop will be distinguished by its emphasis on exploring general representations and reasoning methods that can apply across many different domains.”

More info on papers, panels, and doctoral thesis position papers can be found here and here.
