Presenting Our Analysis Tool

Today I performed my final presentation for my senior project. My project, A Tool to Analyze Spoken Dialogue and Pupil Diameter on a Multi-Touch Surface, was the development of a piece of software to help researchers analyze post-experimentation data. This data came from a past experiment, described here. The tool loads this data into a single, …

Transcription and Some Cross Correlation

In one of my previous posts I demonstrated some software I have been working on at Project54. In the past weeks I have added a few features to this project. Originally, the project could import the associated dialogue and display it in the correct time location. This was cool but the user could not edit …

Google Crisis Map

After the disastrous oil spill in the Gulf of Mexico the National Oceanic and Atmospheric Administration(NOAA) developed the Environmental Response Management Application(ERMA). ERMA provides numerous datasets as overlays on Google maps, providing useful information for response organizations. Now with tropical storm Isaac making its way through the Gulf Coast, Google created an application with the …

Visualizing Sound Files on A Multitouch Surface

For most of the summer now I have been developing software to allow for the visualization of sound files.  Other products such as Wavesurfer and Audacity already accomplish this task along with other capabilities. What differs between those programs and the one I have been working on is its use is for the Microsoft Surface. …

Optimizing Graphs on The Microsoft Surface

Recently, while working on a project to visualize .wav files on the Microsoft Surface, I ran into an issue regarding the canvas controls size. While developing this software I am testing with a .wav file about 4 minutes long. Visualizing this file creates a canvas with a width of about 20,000 pixels . . . …

Writing Code in Your Free Time

Practice makes perfect and I recently discovered a perfect website to assist in coding practice: http://projecteuler.net/ This site contains somewhere around 380, math related, programming problems that are open to solve. Once you create an account, the site tracks your progression through the problems. You also gain awards, and can view friends’ progress(I would think …

Analyzing Time Series Data on the Microsoft Surface

In our last demo we showed the simplicity of scrolling through pre-generated time series data on the Microsoft Surface. We have now implemented real data with the same functionality. The new software, seen below, demonstrates basic data visualization and manipulation of Buoy data collected throughout the Great Bay area. The graphing is created using Microsoft …

Data Over Time

To demonstrate the potential for displaying data over time, I created a sample application on top of the InfoStrat.VE(virtual Earth). This sample program allows the user to scroll through MatLab generated data over a time frame of nine years. This type of visual data display could make analyzing time series information more interesting and fun. …

Mapping Data On The Microsoft Surface Within InfoStrat.VE

Over the Winter Break here at Project54 I have had the chance to work on developing an application for the Microsoft Surface. This project uses the InfoStrat Virtual Earth software, which provides an excellent template of an interactive 3D world using Bing Maps. My application uses environmental data (in this demo sediment levels in water). …

Incredibly Realistic Android

Unlike the creepy animatronic people in Disney Land, the Geminoid DK, while still kind of creepy, is a stepping stone in android research. The android is controlled by motion capture technology. A user sits at a computer which replicates their facial movements. So as of right now it still could be just animatronics, BUT, it …
