This is a GUI Testing Tool and concept to automatically analyse and test any GUI with a model based approach. This is the final thesis for my academic studies.

Idea

Testing Graphical User Interfaces (GUI) is done very differently in commercial and academic environments. In commercial environments GUIs are tested with the simple and convenient Capture and Replay method. Academically developed GUI test methods use powerful but inconvenient model based approaches on the other hand.

My approach combines both methods to a convenient but powerful GUI testing method. The basic idea is the following:

GUI Test Diagram Overview

  1. The user executes example sequences on a GUI
  2. A Model of the GUI is Generated
  3. Test Sequences on the Model are Automatically generated
  4. The Test Sequences are automatically executed on the GUI

The GUI Models stay compact and clear because they use hierarchies and orthogonality.

A systematic combinatorial approach generates the Test Sequences. This keeps the sequences complete but lean.

Features

Convenient but Powerful GUI-Testing • Capture-&-Replay Approach • Model Based • Systematic Test Sequence Generation • Automatic Model Generation • User Friendly GUI Models • Complete but Compact Test-Sequences • Test Arbitrary GUIs

Prototype

As part of my final thesis I also developed a prototype. The prototype is a Plugin for the commercial testing tool TESTONA. You can see it in action here:

Context

This was a self organized project as an employee in the Berner & Mattner enterprise.

To realize this project I worked together with many other teams. I modified and integrated parts of their work into my GUI Testing Tool.

Details

I released a scientific paper   as part of this project. I also released the final thesis  and the final presentation  (in german).

Computer Vision algorithm and algorithm to find and analyse patterns in photographs and images. This is a Research Student Paper.

Context

One Idea of Augmented Reality is the mirror below. This mirror shows an altered version of you. Thus it allows you to select your clothing in a menu. You don’t need to change it in reality.

Computer Vision - Virtual Mirror

One component of this augmented mirror is an algorithm to analyse the real clothing.

I developed an algorithm which analyses the structure of clothing and fabric to find patterns.

Idea

The algorithm takes an image of the clothing as input and extracts the structure (mesh) and texture seen in the image.

Computer Vission - Image to Structure

Extract the Structure (Mesh) of  an Image

Computer Vision - Extract Texture

Extract the Texture of an Image

Using this structure new textures could be applied to the structure to complete the mirror.

Computer Vision - Bulding Facade

The developed algorithm is generalized enough to even be applicable to analyse other images, like regular facades of buildings.

The algorithm was implemented in C++ and evaluated on multiple images.

Details

I published the complete student research paper  (in german).

For one year I worked at the Humboldt Universities – Artificial Intelligence Workgroup. My focus was on researching new ways of grasping and walking for for humanoid robots.

Background

The Idea was to merge the information of multiple sensors (acceleration, pressure, camera, etc.) instead of using every sensor on it’s own, to improve the grasping and walking abilities of humanoid robots. Also additional sensors where added.

Technologies

  • Hardware: Nao Robots, additional modular sensors (e.g. acceleration)
  • Software: C++

Results

The research resulted in promising new approaches for adaptive walking an grasping. A detailed paper on one of the grasping approaches was released: 

Nao addaptive grasping

Nao Robot grasping objects of different weight and stability using the same adaptive algorithm and additional sensors.
