Visiting the HCI Group at the University of Konstanz

Recently I had the pleasure to visit old friends at the Human-Computer Interaction Lab at the University of Konstanz. This was a really nice and relaxed visit, while also super busy. The first day I was the external thesis opponent on the PhD Thesis of Jens Müller. He did a really nice presentation of his work on co-located and distributed augmented reality, as presented in his CHI 2017 paper. The next day, we had a chance to go over the SmartAct Project and dig into some very technical details on how to collect sensor data from the Movisens sensor via BTLE. It was nice to study code rather seeing polished presentations.

UBISS 2018

I was part of organizing the 9th International UBI PhD Summer School 2018 (UBISS 2018) in Oulu, Finland, June 4-9, 2018.

I was running Workshop B on Wearable and Mobile Health and Behaviour Tracking together with Denzil Ferreira.  This was a super nice experience and I enjoyed spending a week diving into technical details on sensing frameworks for mobile sensing, especially the AWARE Framework done by Denzil (while I did tell him that I did the original AWARE Architecture back in 2004 😉 ). Also, getting to know Timo Ojala (or “Timppa” ??) was really a pleasure.

ReticularSpaces

In general, most contemporary computing (hardware, operating systems, and applications) lack support for multitasking, mobility and collaboration across multiple devices. ReticularSpaces was designed as a multi-device smartspace technology for collocated collaboration.

It consists of a runtime infrastructure for ad-hoc discovery and integration of collocated devices, and a novel user interface technology for interacting with touch-enabled interactive displays ranging from small personal digital assistants (PDAs) to very large wall-based and tabletop displays.

AWARE Architecture with AwarePhone and AwareMedia Applications

The AWARE architecture was built as part of the AWARE project. The architecture was a general-purpose architecture for maintaining ‘context-based social awareness’ within a workplace . It was designed to support the safety- and time-critical work on a surgical department and supported two proof-of-concept end-user applications; the AwarePhone and AwareMedia systems .

Giving a talk at the new Center for Digital Health @ Lancaster University

I was visting my old friend and phd student Steven Houben the other day who invited me to connect up with the Ubicomp crew at Lancaster University — and in particular to meet Sumi Helal, who is now appointed Chair in Digital Health.

While being there, I gave a talk. The title, abstract, and slides are available here.

Title: Personal Health Technology — Opportunities and Examples

Abstract: In this talk I will provide an overview of the research done at the Copenhagen Center for Health Technology (CACHET). I will provide the background of this research, define what we mean by personal health technology and how this related to other types of health technology, and come with concrete examples from our different research projects. In particular, I will use my own research into the use of smartphones in the monitoring and treatment of mental health, as an example.

 

The Mini-Grid Framework

The main challenges with existing Grid Computing approaches is that they require high technical knowledge and dedicated hardware and software resources. For these reasons, the deployment and operational cost of such grid systems is substantial, preventing their adoption and direct use by non-technical organizations and users, such as biological researchers in a small university lab. Only a relatively few dedicated scientists use the classic grids like Globus; and setting up projects in volunteer computing grids like BOINC is rather centralized and require running a dedicated server infrastrucure.

In contrast to these large-scale grid infrastructures, our goal has been to create a distributed and ad-hoc grid computing platform for scientist to use as part of their work in the biology laboratory.
