Attentive-UI

Research project on attentive UI for Android devices.

by Li Sirui, Department of Computer Science, The University of Hong Kong.

Overview

The system is the implementation of Attentive Gestural User Interfaces, which make use of eye input data from eye trackers to augment touch-screen interfaces.

Supermonkey, trackerd are core components of the system. The folder scripts includes tool scripts of the system. MonkeyDemo and FactFinder are applications running on the system. HoverLib is an interface library used by the applications.

The system is developed and tested using Tobii X1 Light Eye Tracker and ASUS Nexus 7 (2012) Android tablet.

trackerd

Daemon for eye trackers. It works as a service that provides network interfaces for controlling the eye tracker as well as the ability to send eye-tracking data over the network.

Runtime environment:

  • Windows
  • Python 2.6
  • Tobii SDK 3.0 RC1 (now known as Tobii Analytics SDK) for Win32
  • A Tobii eye tracker that is supported by the above SDK

Run:

python trackerd.py

Network:

Listens to port 10800, connects to Monkey via port 1080.

SuperMonkey

A client for trackerd, which controls the eye tracker on the host PC from Android device. It is a regular Android app that connects to trackerd via TCP sockets and provides an easy-to-use graphical interface for users.

A modified version of UI/Application Exerciser Monkey by Android is bundled with SuperMonkey.

Runtime environment:

  • Rooted Android 4.2

Development environment:

  • Android SDK 14+
  • Android SDK Platform with internal classes (please refer to this)

Install monkey:

  1. Install SuperMonkey just as a normal app.
  2. Put file scripts/supermonkey.sh into /data/ on Android file system
  3. Correct its permissions.

Please see scripts/install_monkey.bat for details.

Run monkey:

  1. Connect Android device with USB Debugging.
  2. Set up port forwarding with ADB: adb forward tcp:1080 tcp:1080
  3. Run monkey from Android shell:
sh /data/supermonkey.sh --port 1080 --ignore-crashes

Then you can start trackerd and SuperMonkey app. Please see scripts/monkey.bat for details.

Network:

Monkey listens to port 1080 on the Android system. Supermonkey connects to trackerd via port 10800.

HoverLib, MonkeyDemo, and FactFinder

HoverLib: Library project of Android interface components that supports attentive input.

MonkeyDemo: Demo application for the above interface components.

FactFinder: Renamed as "FoodFinder" in its interface, sample application that makes use of the components.

Note: The interfaces are optimised for 7-inch screen with 1280×800-pixels resolution in landscape mode. Slight changes to layout might be needed on other configurations.

Runtime environment:

  • Android 4.2

Development environment:

  • Android SDK 16+
  • Android support library v4 and v13
  • ActionBarSherlock 4.4.0 with a tiny bit of modification

You can find the modified ActionBarSherlock here.

The applications also include source code files from Android Open-Source Project (AOSP) and Android swipe-to-dismiss mini-library by Roman Nurik.
