Adding Hypermedia as the Engine of Application State to RESTful Web Services

Aufgabenbereich: Ableitung von Service-Spezifikationen

Bearbeiter: noch nicht vergeben

Beschreibung:

- Motivation:

The REST (Representational State Transfer) architectural style includes the principle of Hypermedia as the Engine of Application State (HATEOAS). Response messages of HATEOAS compliant web services contain all possible valid states the web service can take in a next step. Thus, such web service rep-resent a finite-state automaton. Clients that use the web service, only need to know its initial states. Ideally, the clients do not need to be adapted in case this automaton changes afterwards. Many of today's web services that claim to be RESTful do not consider HATEOAS. Such web services are not fully compliant with REST.

- Task:

The task of the bachelor's the-sis is to support developers in making their RESTful web ser-vices HATEOAS compliant. This is to be achieved by us-ing an existing technique that mines behavioral models (pe-tri nets or BPMN models) from call logs. A web service's states and transitions can be represented by such behav-ioral models. These models can be used to determine all next possible states of a web service. The response messages of non HATEOAS compliant web service shall be automatically expanded by the information about the next valid states. Hence, this approach would help to evolve RESTful web services.

Cross-Device Integration of Windows, MacOS, or iOS Applications

Motivation

Today, our favorite applications are distributed across multiple devices, e.g., we write documents using office applications on desktop computers, share texts and images using messenger on smartphones, or listen to music using our favorite streaming app on smart TVs. Unfortunately, integrating apps running of different devices is often not supported, instead manual effort or workarounds have to be used to increase the user experience across multiple devices. In our previous work [1, 2], we already developed an approach allowing to integrate services provided on Android devices into applications running on other devices. In this thesis, the approach shall be extended to other platforms, namely Windows, iOS, or MacOS.

Task

 

  • Analyzing current means  for inter-application communication on one of the following platforms: Windows, iOS, or MacOS. 
  • Design of an approach to realize the cross-device integration of applications running on one of these platforms (e.g. by using adapters)
  • Implementation of a prototype which enables the cross-device integration for the respective platform and integrates with our current framework
  • Validating the approach by applying it for various applications

Requirements

  • Familiar with Windows, MacOS, or iOS development
  • Having a device with the respective platform

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!
