Let the AR research journey begin (2018-11-29)

Tagged as: blog, AR, AR overview
Group: G This blog entry gives an overview over all the questions and possible research directions that we found during our initial literature research.

Good evening everybody!

Today we want to collect all our questions that occurred during our initial research. We read and summarized some surveys and a book chapter about Augmented Reality (AR). These include the work of Billinghurst, Clark, & Lee (2015), Dünser & Billinghurst (2011), Dünser, Grasset, & Billinghurst (2008) and Gabbard & Swan (2008). Besides, we had a look at a presentation from Marcus Tönnis from the Technical University Munich about the topic “Development Cycles for Usability Testing in Augmented Reality” (Tönnis, o. J.). They should serve as information sources for ourselves, so that we gain an overview and get an insight into the complex topic of Augmented Reality.

The questions should be a starting point for our research and should help to formulate our concept and main research questions. They are ordered along different topics.

Definition

  • What is an AR application and how can it be defined? Which components should be taken into account, when defining an AR application?
  • What are the obstacles of AR? What are the opportunities of AR?
  • What is the difference between Augmented Reality, Virtual Reality and Ubiquitous Computing?
  • What is the overvalue of an AR application and how do AR applications support the user in fulfilling his goal?

Historical Background

  • What are the milestones in the history of the development of AR applications? How did the technologies evolve over time?
  • How evolved the idea to begin with a research in the field of AR? What was the first AR application?

Application types and characteristics

  • Which types of AR applications can be found and how can they be classified? Which characteristics do these groups have?
  • For which use-cases is AR an appropriate medium and why?
  • How does the level of perception shifting in an AR application have an effect on the user’s experience? What does it mean for the design and evaluation of these applications?

Interaction Techniques and Technology

  • What are the underlying technologies of AR?
  • Which hardware and software are necessary?
  • Which types of displays, user interfaces and tracking methods are there?
  • How can the user interact with AR applications?

Design and Implementation

  • How can AR applications be implemented?
  • What needs to be considered, when designing and implementing an AR application? Which problems might occur?
  • How can effective user interfaces and interaction techniques in the field of AR be designed and implemented?

Guidelines

  • Which guidelines and patterns are available for designing AR applications that lead to an improvement of the user experience?

Evaluation

  • Which methods are available for evaluating AR applications? What are the challenges?
  • (Why) Is the evaluation of AR applications difficult?
  • What are the differences between the evaluation methods in general?
  • Which guidelines can be applicated for the evaluation of an AR application? Is there a scheme that can be observed in different cases?
  • Which influence does a small amount of participants have on the validity of a user-based evaluation? What is a recommended amount of participants in the field of AR evaluations?
  • What research trends are available in the field of AR?
