Collecting a dataset of information behaviour in context

We collected human - computer interaction data (keystrokes, active applications, typed text, etc.) from knowledge workers in the context of writing reports and preparing presentations. This has resulted in an interesting dataset that can be used for different types of information retrieval and information seeking research. The details of the...

Unobtrusive Monitoring of Knowledge Workers for Stress Self-regulation

In our connected workplaces it can be hard to work calm and focused. In a simulated work environment we manipulated the stressors time pressure and email interruptions. We found effects on subjective experience and working behavior. Initial results indicate that the sensor data that we collected is suitable for user state modeling in stress...

Term extraction for user profiling: Evaluation by the user

We compared three term scoring methods in their ability to extract descriptive terms from a knowledge worker's document collection. We compared the methods in two different evaluation scenarios, both from the perspective of the user: a perterm evaluation, and a holistic (term cloud) evaluation. We found that users tend to prefer a term scoring...

New ways of working: Does flexibility in time and location of work change work behavior and affect business outcomes?

In the changing modern economy some new factors have been addressed that are of importance for productivity and economic growth, such as human skills, workplace organization, information and communication technologies (ICT) and knowledge sharing. An increasing number of companies and organizations are implementing measures to better address...

Unobtrusively Measuring Stress and Workload of Knowledge Workers

Imagine a typical working day of a knowledge worker, i.e. someone who is predominantly concerned with interpreting and generating information. Bob gets into the office at 9, starts up his computer, takes a look at his mails and calendar and plans what things he has to do this day. Then he starts working on one of the important tasks that have to...

Real-time task recognition based on knowledge workers’ computer activities

Motivation – Supporting knowledge workers in their self-management by providing them overviews of performed tasks. Research approach – Computer interaction data of knowledge workers was logged during their work. For each user different classifiers were trained and compared on their performance on recognizing 12 specified tasks. Findings/Design –...

Automatic recognition of context and stress to support knowledge workers

Motivation – Developing a computer tool that improves well-being at work. Research approach – We collect unobtrusive sensor data and apply pattern recognition approaches to infer the context and stress level of the user. We will develop a coaching tool based upon this information and evaluate its effectiveness in user studies. Findings/Design –...
