Three accepted papers to HCI International

The interaction design group is part of the 20th international conference in human-computer interaction (HCII) this summer with three accepted full papers. All three papers will appear afterwards in Springer Lecture Notes in Computer Science (LNCS).

Harald Holone in cooperation with Trenton Schulz and Jo Herstad from Oslo University wrote a paper about “Privacy at Home: an Inquiry into Sensors and Robots for the Stay at Home Elderly”.

The elderly in the future will use smart house technology, sensors,
and robots to stay at home longer. Privacy at home for these elderly
is important. In this exploratory paper, we examine different
understandings of privacy and use Palen and Dourish’s framework to
look at the negotiation of privacy along boundaries between a human
at home, the robot, and its sensors. We select three dilemmas:
turning sensors on and off, the robot seeing through walls, and
machine learning.  We discuss these dilemmas and also discuss ways
the robot can help make the elderly more aware of privacy issues and
to build trust.


Susanne Stigberg  submitted an invited paper with the title “Music at your Fingertips: Designing Mobile Interaction Interfaces for Runners”.

The paper presents a technique to simplify the making of mobile interaction
interfaces. We often use smartphones while moving, resulting in non-optimal or even unsafe mobile interactions. Better interactions need to be created with locomotion in mind and experienced in context. Consequently interactive behavior of mobile devices cannot be sketched, but must be made to be experienced. Making mobile prototypes is time-consuming and requires programming literacy. It often involves the making of an input artifact; establishing a connection between artifact and mobile phone; and implementing an application on the mobile phone for exploring the interactive behavior. The use of commercial smartphone automation tool eliminates the need for reimplementing available smartphone functionalities, and invites non-programmers into the process of making mobile interaction interfaces. To illustrate the proposed technique I present a case study of a wearable prototype to control music on the mobile phone by tapping one’s fingertips.


Klaudia Carcani in cooperation with Oslo University submitted a paper on “Exploring Technology Use in Dance Performances”.

The objective of the paper is to critically reflect on how research through design (RtD) can be used to gain knowledge of a new design context within HCI. We use the design research triangle presented by Fallman [1] as the framework for analyzing and to reflect upon the RtD process. The design context to which this new knowledge was applied to is within the area of dance and technology. Our design inquiry, therefore, using the term we coined – addhance, seeks to either add a sort of novel experience, or enhance a dance performance. We, thus, taking an RtD approach, explored how the dancers could compose music by moving their bodies. We designed a Kinect based system that captures dancer’s movements and translates them into music. Intending to addhance the choreography, enlighten dancers’ movements and bring a new disrupted workflow of both creating and enjoying a dancing performance.

 

Mobile Ubiquitous Multimedia 2017

Over the last three days I attended the 16th International Conference on Mobile and Ubiquitous Multimedia (MUM17) in Stuttgart, Germany. MUM is a small single-track conference with lots of interesting presentations, posters, demos and art tracks. It is a SIGCHI conference in cooperation with ACM.

 

I really enjoyed the keynote speakers. The opening keynote speaker on Monday was Dr. Shengdong Zhao, Assoc. Professor in Computer Science at National University of Singapore. He talked about the new interaction paradigm and focused on a human-centric design process. He imagines interaction with technology through two devices a head device and a hand device. Similar to my research he believes that accessories for input and output can be used to interact with the central hub (right now the “mobile phone”) to deliberate us from looking down at the technology and focus more on the world around us.

 

Dirk van den Boom,  a German Science-Fiction-author, consultant, journalist and extraordinary professor for political science at the University of Muenster, was the closing keynote speaker on Wednesday and talked about the implications of social media in mainstream knowledge and politics. He explained how technology helped to spread non-facts or fake news and distresses the need for educating how to “think critically” in schools. He believes that we cannot argue with idiots, but we can try to prevent others to become idiots through using sarcasm, making fun of their fake news and theories.

On Tuesday I really enjoyed the presentation from Wolfgang Hochreiter et al. with the title  No Need to Stop – Exploring Smartphone Interaction Paradigms While Cycling. He talked about the same problems I experienced in my research, the “stop-to-interact” paradigm and how to allow interaction in motion. Ashley Colly presented Investigating Drone Motion as Pedestrian Guidance , reminding me at the work from Florian Müller about Jogging over a Distance. The idea is that users have personal navigation drones helping them to find their way in unknown locations. An intriguing idea to have a small hover-able robot that helps me finding my way!

Last but not least I really enjoyed the demos and art tracks Monday evening. My three personal favorites:

 

I presented a poster about the A Critical Review on Participation in Mobile Interaction Design Research on Tuesday morning and won the Best Poster Award. Woohoo!

 

Greetings from MobileHCI in Vienna

This week I visited MobileHCI in Vienna. Its the 19th International Conference on Human-Computer Interaction with Mobile Devices and Services under the umbrella of the ACM Special Interest Group on Computer-Human Interaction (SIGCHI).

Simplifying the Making of Probes, Prototypes and Toolkits in Mobile Interaction Research using Tasker

I presented my work on Simplifying the Making of Probes, Prototypes and Toolkits in Mobile Interaction Research using Tasker. This paper presents a technique to support the making of mobile interaction interfaces for controlling the smartphone. We often use smartphones while moving, resulting in non-optimal or even unsafe interactions. Better mobile interactions need to be created with locomotion in mind and experienced in practice. But making and testing new interaction interfaces is time-consuming. It often involves the making of an input device; establishing a connection between device and smartphone; and implementing an application on the phone for testing interactions with the input device. This paper reports from three ongoing projects on how a commercial available automation tool called Tasker can be used for coupling phone functionalities to new input devices, eliminating the need for implementing a complete phone application, and enabling flexible, reusable, and easy making of interaction interfaces for smartphones.

MobileHCI is a rather small community and I was happy to meet some familiar faces. At the same time  I got some really nice ideas for future projects.  EMS, electrical muscle stimulation seems to be the next big think. There was a demo on FootStriker – An assistance system for real-time running style correction using EMS by Wiehr et al. It seems to do its job, I just wonder if their proposed optimal running style really is optimal for everyone? I have friends that got injured of too much forefoot running. Tim Duente presented Zap++: A 20-Channel Electrical Muscle Stimulation System for Fine-Grained Wearable Force Feedback and showed how he could control his hand through muscle stimulation, a bit spooky if you ask me. My best price for effort in making goes to Michael Ortega for his EXHI-bit: a Mechanical Structure for Prototyping EXpandable Handheld Interfaces. Really cool to listen to him explain how their design process developed and how they iterated their prototype. I wish there was more of these types of papers. And one big applause for the organizers. Both keynote speakers were women. There are lots of competent women out there, if anyone doubted. Tomorrow I will travel back to Halden with lots of new ideas and plans for the time after my PHD, if there will such a time?

Designing Interactive Systems

This week I visited DIS 2017 in Edinburgh. DIS stands for Designing Interactive Systems and is an annual conference owned by the ACM Special Interest Group on Computer-Human Interaction (SIGCHI). DIS brings together  designers, artists, psychologists, user experience researchers, systems engineers, and many more,  to debate and shape the future of interactive systems design and practice.

I presented a poster called Mobile Hand Gesture Toolkit: Co-Designing Mobile Interaction Interfaces. This poster presents a mobile hand gesture toolkit enabling the co-design of mobile interaction interfaces for runners. Runners are using smart phones for exercising more than ever before. However previous research has shown that mobile devices are not suitable for interactions in motion. This poster presents a method to probe such interactions for and with runners using a participatory design approach. We demonstrate in a pilot design workshop how participants can tell their mobile interaction story, make their own mobile hand gesture interface, and enact their story using their created artifacts. These artifacts are functional and used in the participants’ everyday workouts. The participants can revise them as an ongoing practice of design-in-use.

Conferences are always a good place to get inspired. For me the most futuristic talk on Monday was Exploring Interactions and Perceptions of Kinetic Wearables hold by Cindy Hsin-Liu Kao, MIT Media Lab. They explored the role of accessory-like kinetic wearables in relation to personal style: What does it mean to wear kinetic accessories and why would one be motivated to do so? They developed Kino, a kinetic accessory system which enables both aesthetic and functional clothing-specific design possibilities. On Tuesday I really enjoyed listening to Joe Marshall about Touchomatic: Interpersonal Touch Gaming In The Wild. In his talk, he describes a long term, in-the-wild study of a two-player arcade game which is controlled by gentle touching between the body parts of two players. It reminded me a lot about the work of Florian ‘Floyd’ Müller on Bodily Games and Exertion Games. Tomorrow I will travel back to Halden with lots of new ideas and plans for the fall 🙂

Probing Privacy in Practice

This week Joakim and Susanne attended the ACHI conference in Venice. Here we presented our project about running and sharing instant video to social media. You can read more about the project in Norwegian from an article at Elektronikknett.

For the project we used a mobile phone strapped to the runner in a neoprene sport belt, that was remotely controlled by a sport glove detecting hand gesture for recording and sharing video. This scenario was inspired by the demand of semi-professional and advanced amateur runners  for new technologies supporting recall and close contact with supporters throughout running events. And of course the interest of social media in live video, as seen by popular applications such as Periscope and Facebook Live.

However our goal was not to test a new prototype, rather to investigate how users participating in running events experience such a technology for instant sharing of video especially in regards to their privacy. To be able to explore privacy we designed a technology probe,that should feel as real as possible for the users. We had to make both design choices regarding technology and social context.

The Technology Probe: a mobile phone strapped to the body & adapted sport gloves detecting hand gestures.

We used available technology such as:

– Mobile phones with functionality for instant video sharing to social media
– Lilypad, an Arduino micro controller to develop the gesture sport glove
– A bluetooth module enabled communication between phone and glove.

For the social context we made the following design choices:
– Placement of the phone should support wearability
– Hidden technology increased social acceptance
– Red lights on the glove provide easy accessible feedback
– Hand gestures for meaningful interactions.

We deployed our probe at two running events one in Strömstad, Sweden and one in Wolfen, Germany. You can read more about our work and our findings in the article Probing Privacy in Pratice available from ThinkMind Digital Library.
