Advanced HCI Theory & Methods

Advanced HCI Theory & Methods

The Advanced Human-Computer Interaction module is part of the Masters course and refreshes and develops upon qualitative and quantitative research methods.

There were five assignments in total. The first four assignments involved creating a presentation and/or a report within a team.

  1. Here a study was conducted which gathered data about the perceptual accuracy of throwing different weighted objects at targets while both blindfolded and not blindfolded.
  2. Interviews about people’s daily physical activities were conducted and subsequently analysed and coded.
  3. Research and presentation about diary studies.
  4. Contextual inquiry and work models – this study was conducted within a bakery and one of it’s employees.

Final Project: This was an individual project with the requirement of examining transport and technology. I decided to conduct a study on the acceptance of technology in casual cycling. The study was composed of a short semi-structured interview and a cooperative design approach. This user-centered design approach involved sitting down with the user and giving them the tools to create their desired imaginary bicycle. These tools included a sheet showing a human body and a bicycle, some technology cards and tokens. The user was given the freedom to explore the design space and verbally explain their reasoning for their choices.

Afterwards the recorded videos and images were analysed, with the technologies created by the users being coded into ten themes. The top themes to emerge from the study included Safety, Comfort and Convenience.

IoT Design – Masters Thesis

IoT Design – Masters Thesis

My Master’s thesis involved the creation of an Internet of Things interface, which I entitled “HomeNodes”. The HomeNodes interface was projected on to to objects. Users could connect objects together using a touch enabled wall interface and by tapping their smartphone on different objects.

The following is a short summary of my project:

  1.  Conduct low-fidelity prototyping sessions with users to explore the IoT design space.
  2. Research existing interactive systems
  3. Construct a prototype
  4. Test with users and use observation and video analysis
  5. Build a list of topics from this analysis that outlines the important design considerations and feedback for my IoT interface.

Video of the system in action:

The following images are version 1 and 2 of my systems. The green elements in the second image are technologies that I added to make the system more scalable. The thesis can be read and downloaded in full at this link. The code will be available on my GitHub.

Evaluating Experience around Public Interfaces

Evaluating Experience around Public Interfaces

This was the second semester project and involved the creation and evaluation of an interactive public interface. The interface could be controlled using a person’s movement. The project was led by two students and one Research Associate from the Urban HCI Lab. Two quantitative studies were completed with 60 people.

The final version made use of Processing, a gesture control program made by Wout Standaert and a projector. Images and the summary poster PDF can be found below.

Cinestar Usability Prototype & Evaluation

Cinestar Usability Prototype & Evaluation

As part of the Usability Testing course of my Master’s degree we were asked to analyse a website we felt was not very usable, built iterative prototypes and subsequently do a quantitative usability evaluation.

Our team for the project chose the Cinestar.de website. The first part of the course was analyzing the chosen Cinestar website including picking out violations of Norman’s Usability Principles. Personas were created to explore the potential variety of users of the system.

Persona for cinestar website

Next was requirements analysis, building of two low-fidelity prototypes and then quantitative analysis. Two low fidelity prototypes were made using Moqups.com, each one created by one half of the team.

One Low Fidelity Prototype

To close off the course a mid-fidelity prototype was made and then analysed with users. The mouseflow Javascript library was used to gather visual data on how the user traveled through the website, how long they took and what were the most viewed and clicked sections.

The Investigators Project

The Investigators Project

This project was part of my M.Sc in Human-Computer Interaction and took place between April – September 2016. The project was worked on by more than 15 people, 10 of which were students from Computer Science and Media Architecture. Two workshops were completed with the artist Krzysztof Wodiczko in preparation for the final event. The project was included as part of the Kunstfest Weimar event.

One of my main responsibilities in the project was managing and reconfiguring the WordPress website and writing content. Most of the processes and events have already been documented on the website which cn be found at:
