Projects

AR Signs: AR displays and perception of ISO signs
10.11.2015

Abstract:

In this project, you will lead studies using a head mounted display to view overlays of ISO signs. Augmented Reality (AR) aims to extend a person’s view of the world with computer generated information in real-time, has targetted industrial processes since its introduction as a field. Advances in miniaturization and sensor technologies sparked a range of novel applications where AR promises an ideal solution in industrial processes. ISO sings are ubiquitous in industrial settings. They are used to alert dangerous areas, locate equipment, indicate escape routes and others. This project analyses perceptual effecfs of overlaying ISO sings on the real world. This project evaluates how ISO signs are perceived through AR. In particular, we are interested to find out if different industrial backgrounds pose interference that confuses signs. We also want to establish which sign categories are better perceived in AR.
Lead: Carla Barreiros and Eduardo Veas

Bio:

Carla is researcher at Know-Center and PhD Candidate at KTI. Carla's research interests span a broad spectrum of wearable and mobile technology to present information in ways that affect people. A key challenge in her work is to reach people emotionally with digital interfaces. Along these lines she is investigating methods to represent information with natural interfaces.
Sensory substitution/augmentation
11.11.2015

Abstract

In this project you will study whether/how people learn to decode information from a tactile display prototype. Much of the digital information we deal with is presented visually and we have acquired a broad understanding and basic methodology to design for visual interfaces. However, at times, people are already engaged in an activity that requires visual concentration or visual stimulation cannot be used for other reasons. This project systematically studies how to represent information with a tactile display. You'll specifically help us find out characteristics of a vocabulary and messages that can be conveyed with the tactile display.
Lead: Granit Luzhnica, MSc.

Bio:

Granit is researcher at Know-Center and PhD Candidate at KTI. His research interests dwell on the topic of sensors and actuators for mobile multimodal interaction. Granit is involved in designing and testing a number of mobile prototypes involving sensors at Know-Center. A key challenge in his work is the elicitation of behaviour patterns. With each prototype, it becomes necessary to determine patterns that define a behaviour from raw sensory data. His expertise in machine learning and classification algorithms is key to investigate models (activity, behaviour) from sensory data.
Interactive Topic Modelling
12.11.2015

Abstract

This projet investigates how we organize knowledge from large text collections. The ability to analyze and organize large collections, to draw relations between pieces of evidence and build knowledge are all part of an information discovery process. Continuous shifts in goals and information needs guide the acquisition of knowledge – cognitive constructs of topics related by exemplary resources–. This project investigates the search process and knowledge building process with a tool of our design. We are interested in finding out if people put trust on a tool recommending content and how knowledge is constructed interactively using this tool.
Lead: Cecilia di Sciascio, Lic.

Bio:

Cecilia is researcher at Know Center and PhD candidate at KTI. Her research interests concentrate on search and recommendation interfaces for large collections of data. She has developed a self contained system for search and exploration of scientific content, which is currently integrated into the EEXCESS platform. A key challenge in her work has been the nature of unstructured data and the definition of methods to represent features that can be used to establish relationships therewith. Cecilia's work complements visual analytics and recommender systems techniques to deliver the right information in a clear, understandable way.
Recommending Visualizations
12.11.2015

Abstract

This project investigates the effects of recommending visualizations. Coming up with a good visual representation is a challenge for most people. It takes a number of iterations until the right configuration of a visualization is found. This project uses a multi-stage recommender system, which prepares recommendations appropriate for a dataset and matching the interests of the user as recorded in her profile. Participating in this project, you will investigate methods for users to express their preferences for visualizations and datasets. Additionally, you will work on studies that help us understand the aspects of interaction that people apply the most as well as those which are problematic.
Lead: Belgin Mutlu, MSc.

Bio:

Belgin is researcher at Know Center and PhD candidate at KTI. Her research is dedicated to investigate methods to recommend visualizations. She has studied a number of algorithms to recommend visualizations: rule based, collaborative filtering, content based and hybrind. The key challenge in her research is to find a way to simply derive and establish the features that make a visualization useful for a particular person. Her research is defining new ways to interact with data, whereby visualizations are recommended for the data at hand using algorithms that account for user preferences and past experience.

The course is project based. For each class students take turns to moderate and take part in evaluations. For the course, the student will:

  • choose a project topic to design and evaluate from concept to prototype
  • choose a project topic to moderate (play the role of user for peer projects)

Readings

Continuous evaluation serves as a research methodology in many fields of Computer Science. This lecture is intended to familiarize you with a range of methods applied when continuous evaluation is used in research, desing and innovation. The following is a list of the main textbooks that will be referenced throughout the lecture. You can borrow them from the university library, or come to Eduardo's office to browse them (make an appointment).

User Centric Design and Human Factors

Foundations for Designing User Centred Systems. Ritter, Baxter, Churchill, is a thorough reference for the UCD methodology. It dedicates a good portion of the book to understanding people, human factors, behavior and cognition. The chapter on evaluation provides a good, general entry point to the different aspects of evaluations. In the lecture, this book serves as reference for UCD but also for considerations about the user capabilities. Link

Formal Evaluation: Statistics for Analysis

Discovering Statistics Using R (Andy Field, Jeremy Miles, Zoe Field) is our main reference to the implementation of statistics methods used for analyses of evaluation results. It is a thorough reference with example implementations in R, covering the major aspects of research and analysis of evaluation results introduced in this lecture. It is a recommended read, which will be heavily used in weeks 3-6, and will surely accompany the students beyond the lecture in their carreer.

What this course is NOT

This course is not an introduction to HCI nor to visualization. For general courses on the topics covered visit:

This course will not deal with web usability, as that topic is extensively covered by Keith Andrews course on Information Architecture and Web Usability. Instead the course concentrates on providing a solid background on the different evaluation methods as applied in a UCD continuous evaluation process. This course is no replacement for an advanced statistics lecture. Descriptive and inferential statistics methods will be used to guide the preparation of data, the performance of appropriate statistical tests, their interpretation and reporting of results.

Who should attend this course

This course is particularly suited for post-graduate students (Msc.) and researchers (PhD.) investigating or developing novel metaphors to interact with computers and machines. It is also suited for researchers trying to understand the user behaviour and how it is influenced by technology. This includes psychology majors as well as educators. Students in the final year of their Bak. may benefit from this course too.
