Software-Understanding of Evaluation tools for 3D-Models with methods of Software Testing

Motivation

Additive manufacturing, often known as 3D printing, describes the group of manufacturing processes in which the objects that are manufactured are generated by the deposition of material. Despite the large variability compared to conventional manufacturing processes, product models must be checked for producibility before production.

However, the existing analysis tools often evaluate models very differently, which is why an analysis of the existing solutions should be carried out as part of this master's thesis. The common tools provide visual feedback regarding the producibility of a model. The basic ability to correctly evaluate a model is to be examined on the basis of the feedback. Another important point is the test for rotational invariance. Common methods of software testing should be used to carry out the tests. These include steps from test planning through test execution to test completion. Research goal is the generation of knowledge about the real functionality of the analysis tools. Example

Description of the Task

- Introduction to:

  • Basics of additive manufacturing
  • Production feasibility analysis in additive manufacturing
  • Basics of software understanding
  • Basics of software testing

- Design of test scenarios

- Creation of suitable test geometries

Development and Evaluation of Augmented / Virtual Reality Applications

Motivation

Cognitive assistance systems offer a variety of possible use cases especially in the context of learning environments in artificial reality (AR/VR) scenarios. In our project it‘s OWL AWARE, we are researching new application scenarios, development methods and new forms of interaction to support the development of novel assistance systems.

In this subject area there are various open Bachelor and Master thesis topics, which deal with the systematic development and evaluation of AR/VR applications.

Possible Topics

  • Systematic literature survey for AR/VR development methods
  • Prototypical development of AR/VR applications for different scenarios (assembly, maintenance, navigation, …)
  • Development of new modeling languages to capture AR/VR specific aspects
  • Development of model-driven or component-based development methods for AR/VR applications
  • Usability Evaluation of AR/VR applications in terms of efficiency, effectiveness, and user satisfaction
  • Data-driven UX Evaluation of AR/VR applications through user feedback (human-in-the-loop, digital-twin approaches)
  • Conception and development of context-adaptive AR/VR applications
  • Continuous quality assurance and software testing for AR/VR applications

If you are interested in one of the above mentioned topics or have your own topic suggestions, feel free to contact us!

Augmented Reality Assisted Robot Programming

Augmented Reality (AR) is a user interface metaphor, which allows for interweaving digital data with physical spaces.AR relies on the concept of overlaying digital data onto the physical world, typically in form of graphical augmentations in real-time. Augmented Reality (AR) techniques are applied in different domains (engineering, entertainment or education & training) and provide a cognitive assistance for various activities (maintenance, programming, configuration etc.). Especially in the context of robot programming, AR provides several advantages in the programming process. The operator gets instant real-time, visual feedback of a simulated process in relation to the real object, resulting in reduced programming time and increased quality of the resulting robot program. Main goal of this thesis is to design and implement an augmented reality assisted robot programming environment.The robot programming environment shall focus on the DobotMagician system which can be represented as a 3D Model and projected via AR techniques in the working environment to support the programming task of an operator.

Task:

  • Literature research on the topics AR and Robot Programming
  • Conception and Design of an AR Assisted Robot Programming Environment
  • Prototypical Implementation of an AR Assisted Programming Environment for the Dobot Magician System
  • Experiment-based evaluation of the implemented approach

Further details regarding the topic and tasks can be found in the attached PDF file.

Development of a virtual reality interface for human-robot interaction

Motivation

Cognitive assistance systems offer a variety of possible use cases especially in the context of learning environments in artificial reality (AR/VR) scenarios. In our project it‘s OWL AWARE , we are researching new application scenarios, development methods, and new forms of interaction to support the development of novel assistance systems.
In this subject area, we are especially interested in the topic of human robot collaboration. With the means of virtual reality interfaces it is possible to control robots remotely, i.e., to teleoperate them. The teleoperation of robots with virtual reality brings lots of advantages regarding safety, supervision from distance etc.
The main goal of this thesis is to design and implement a virtual reality environment which supports remote control of the Dobot Magician system (https://www.dobot.de).

Description of the Task

  • Systematic literature survey on VR interfaces for remote control
  • Prototypical development of a VR application for remote control of Dobot Arms
  • Usability evaluation of VR application in terms of efficiency, effectiveness, and user satisfaction

Conception and Implementation of a Development Framework for Cross-Device AR/VR Applications

Motivation

Augmented Reality (AR) and Virtual Reality (VR) Developers face a proliferation of new platforms, devices, and frameworks. This often leads to applications and interactions being limited to a single platform and makes it hard to support collaborative AR/VR scenarios involving multiple different devices such as HTC Vive, HoloLens and smartphones. For supporting a seamless interaction across various AR/VR platforms, the main goal of this thesis is to design and implement a framework for cross-device AR/VR experience. Based on previous work in this area [1] relevant cross-device interaction scenarios for AR/VR should be identified. The derived requirements should form the basis to create a development framework for cross-device AR/VR applications. An evaluation of the framework should be performed by implementing exemplary cross-device AR/VR scenarios.

Description of the task

  • Systematic literature survey on cross-device AR/VR interfaces
  • Conception of a development framework for cross-device AR/VR applications
  • Prototypical implementation of a development framework for cross-device AR/VR applications
  • Evaluation by implementing and experimenting with exemplary cross-device AR/VR scenarios
