InspectorWidget Iterator

Introduction

InspectorWidget is an opensource suite to track and analyze users behaviors in their applications.

The key contributions of InspectorWidget are:

  1. it works on closed applications that do not provide source code nor scripting capabilities;
  2. it covers the whole pipeline of software analysis from logging input events to visual statistics through browsing and programmable annotation;
  3. it allows post-recording logging; and 4) it does not require programming skills. To achieve this, InspectorWidget combines low-level event logging (e.g. mouse and keyboard events) and high-level screen features (e.g. interface widgets) captured though computer vision techniques.

InspectorWidget is targeted at end users, usability experts, user experience and HCI researchers.

Distribution

InspectorWidget is composed of three tools:

  • Collector: Record (screen), Log (input events)
  • Iterator: Browse (screen + input events), Program (annotations), Analyze (workflows)
  • Processor: Automate (annotations)

InspectorWidget Iterator

The Iterator tool is a web-based application for browsing the recordings of screen and input events, programming annotations and analyzing workflows.

It is based on:

  • dc-js / dc.js: a library for multi-dimensional charting
  • google / blockly: a library for visual programming implementing Scratch
  • ina-foss / amalia.js: a library for browsing spatial/temporal annotations synchronized with video playback
  • mbostock / d3: a library for information visualization
  • square / crossfilter: a library for fast n-dimensional filtering and grouping of records

Installation

First clone the repository. Then open a terminal in the source directory:

  • prepare front-end packages with bower: bower install
  • install node.js dependencies with npm: npm install
  • compile JavaScript dependencies with grunt: grunt
  • prepare the JavaScript code: npm run browserify
  • start the Electron app: npm start

InspectorWidget Iterator is released under the terms of the GPLv3 license.
