Robot-based digital doping

In the world of cycling, lots of attention has been brought upon a ‘doping’ incident on Zwift. The story is along the well-known lines where an athlete, Cameron Jeffers, has taken a chance to cut corners in order to be as competitive as possible.

Digital doping is a phenomena that most likely will become a common problem when the digital-physical boundary in sports become increasingly blurred.

Also have a look at the article, Zwift Hackers Expose the Next Generation of Cycling Doping, that outlines how Zwift could be manipulated.

Att springa fort utför och samtidigt titta på klockan för att se aktuell hastighet är klurigt.

I söndags sprang jag Icebug Backyard trail, ett 16km fantastiskt vackert trail-lopp i skogarna kring Härkeshult och Maderna med start vid Icebugs HQ i Jonsereds Fabriker. Ett verkligen välorganiserat och härligt lopp. Gänget på Icebug vet hur trail ska organiseras.

Loppet var i sin mittsektion och avslutande del en härlig löpning i utförsläge där det fanns mycket goda möjligheter att verkligen trycka på. I en av dessa underbara utförslöpor fick jag ett trängande behov av att se hur snabbt jag verkligen sprang. Dock visade det sig vara mycket svårt att både springa fort utan att snubbla rätt ut i skogen och att snabbtitta på min Garmin Fenix3 för att där se hastigheten. Det fanns naturligtvis en mängd faktorer som påverkade min förmåga att göra så, där min bristande koordination, dåliga syn, maxade puls samt mitt allmänna euforiska läge gjorde att en snabbtitt var klurig att få till.

Svårt att se på klockan när pulsen är på topp och hastigheten hög.

Kanske är det så att detta är något som löpare behöver träna på samt organisera på något sätt. Det finns ju rikligt med generösa inställningsmöjligheter på en Garmin. Kanske kan en mer anpassad design än det som jag hade valt vara en väg framåt. Kan det vara så att framtidens sportklockor behöver känna av vad jag gör och vill, utöver att den ska känna av vad för aktivitet som jag utför.

Det finns lite roliga studier som gjorts kring design av sportklockors grafiska och fysiska gränssnitt.

Bland annat tycks diagramtypen spela roll för hur snabbt och korrekt som vi kan uppfatta värden.

Abstract—We present the results of two perception studies to assess how quickly people can perform a simple data comparison task for small-scale visualizations on a smartwatch. The main goal of these studies is to extend our understanding of design constraints for smartwatch visualizations. Previous work has shown that a vast majority of smartwatch interactions last under 5 s. It is still unknown what people can actually perceive from visualizations during such short glances, in particular with such a limited display space of smartwatches. To shed light on this question, we conducted two perception studies that assessed the lower bounds of task time for a simple data comparison task. We tested three chart types common on smartwatches: bar charts, donut charts, and radial bar charts with three different data sizes: 7, 12, and 24 data values. In our first study, we controlled the differences of the two target bars to be compared, while the second study varied the difference randomly. For both studies, we found that participants performed the task on average in <300 ms for the bar chart, <220 ms for the donut chart, and in <1780 ms for the radial bar chart. Thresholds in the second study per chart type were on average 1.14–1.35× higher than in the first study. Our results show that bar and donut charts should be preferred on smartwatch displays when quick data comparisons are necessary. 

Att pilla med klockan medan man springer
I en annan studie har forskare undersökt hur löpningen påverkas när löparen interagerar med klockan. Seuter, M., Pfeiffer, M., Bauer, G., Zentgraf, K., & Kray, C. (2017). Running with Technology: Evaluating the Impact of Interacting with Wearable Devices on Running Movement. Proceedings of the ACM on Interactive, Mobile, Wearable and Ubiquitous Technologies1(3), 101.

Abstract: The use of wearable devices during running has become commonplace. Although there is ongoing research on interaction techniques for use while running, the effects of the resulting interactions on the natural movement patterns have received little attention so far. While previous studies on pedestrians reported increased task load and reduced walking speed while interacting, running movement further restricts interaction and requires minimizing interferences, e.g. to avoid injuries and maximize comfort. In this paper, we aim to shed light on how interacting with wearable devices affects running movement. We present results from a motion-tracking study (N=12) evaluating changes in movement and task load when users interact with a smartphone, a smartwatch, or a pair of smartglasses while running. In our study, smartwatches required less effort than smartglasses when using swipe input, resulted in less interference with the running movement and were preferred overall. From our results, we infer a number of guidelines regarding interaction design targeting runners.

Behov av studier av användning när folk springer med sina klockor
Det behövs mer forskning kring användning av sportklockor / smart watches. Hur idrottare använder sina klockor i sin träningstillvaro och under högprestation i samband med lopp är hyperintressant men ganska utmanande att studera.

Två spännande innovationer

Under våren är min ambition att fördjupa mig lite i två mycket coola digitala innovationer som på olika sätt skapar helt nya förutsättningar för träning och uthållighetsprestationer.

Den ena är svenska Race Fox som är en digital coach som i realtid hjälper till med att underlätta utvecklandet av ett bättre löpsteg. Race Fox är en cool och spännande pryl i form av ett ‘smart’ pulsband som med tillhörande app ger nya insikter under och efter löppasset. Extra kul är att Race Fox är ett lyckat resultat från svensk IT-forskning.

Den andra är Analytics från Guided Hereos där proffscykeltränaren Mattias Reck med vänner anpassat plattformen från australiensiska Todays Plan till att bli ett grymt digitalt träningsverktyg. I kombination med effektpedaler från ex Garmin så ger Analytics från Guided Hereos grymt djupa insikter.

Förhoppningsvis kommer några systematiska analyser av både Race Fox och Analytics att genomföras inom de närmaste månaderna.

Inspiring papers published 2018

The department of Applied IT head of division of Informatics, Johan Magnusson, asked his fellows about the top-3 papers that has been published in 2018. Since I am Johans manager, I also wanted to (and was asked to) contribute with my list. So here are the three papers from 2018 that has been particularly useful and interesting.

The first paper is published in the excellent venue CoDesign. The paper is co-authored by Eva Eriksson who is a brilliant researcher that a few years ago was part of the division of Interaction Design, during the time when I was the head of division.

Saad-Sulonen, J., Eriksson, E., Halskov, K., Karasti, H., & Vines, J. (2018). Unfolding participation over time: temporal lenses in participatory design. CoDesign14(1), 4-16.

The second paper is written by Helena Karasti and Volkmar Pipek along with Geoffrey Bowker, and contributes to the discourse on infrastructure, design and participation. This paper is a great source for inspiration in the otherwise dull waters of too much management-centric infrastructure papers. It is great to see that the PD-associated people are making useful contributions.

Karasti, H., Pipek, V., & Bowker, G. C. (2018). An Afterword to ‘Infrastructuring and Collaborative Design’. Computer Supported Cooperative Work (CSCW)27(2), 267-289.

The third paper is written by the always brilliant Leysia Palen together with Robert Sodden, and it elaborates on the digitalisation and the data-fication of crisis management. Since Leysia is a thought-leader of the discipline, Crisis Informatics, this paper is an important contribution to further develop the field. The paper is also great since it re-discover Zuboffs concept of ‘informating‘.

Shift in direction

Once and awhile one is confronted by points in time when it is time to reflect upon what one is doing and if there is a need to adjust ones direction in (work-) life. Early this year, I decided to assume a role where I will spend more time on organisational and leadership tasks and actively move away from the domain of emergency and crisis response.

I will continue to adopt ethnography along with design thinking when exploring wicked problems and in shaping new possible solutions. The cases will most likely shift from IT-use in organising large-scale response in emergencies, pandemics and forced migration. Instead I hope there will be studies oriented towards the use of digital technology for coaching in individual and team-based physical performance.

However, the absolute majority of my time will be spent on building and maintaining an organisational infrastructure that allow the scholars at the department of Applied IT to succeed and excel in their professional efforts.

As a consequence of this, the content of this blog will shift focus, away from the domain of emergency and crisis response.

Infrastructure view on refugees use of digital tools on their journey to Europe

Now and then, one stumble across papers that make an impact on how you think about your own research. The other day, I read the following paper by Gillespie, Osseiran and Cheesman. 

Gillespie, M., Osseiran, S., & Cheesman, M. (2018). Syrian refugees and the digital passage to Europe: Smartphone infrastructures and affordances. Social Media+ Society, 4(1) [link]

In this paper they study the use of information technology by refugees during their journey to and through Europe. It was particularly refreshing to see how they use ’affordances’ by Gibson as well as ’ infrastructures’ by Star to unpack how information technology use present  possibilities but also vulnerabilities for refugees. 

This is an insightful paper that opens up an important discussion of the need of more studies on socio-technical dimensions in the refugee context. 

This paper underline the importance of studying groups that typically are not percieved as technology users. This study illustrates how refugees are a very interesting user category in technology use research. Lastly, the paper also shows that a better understanding of sociotechnical entanglement is important in order to formulate meaningful policies in the refugee context.
