Figure: Collecting data with RuuviTag and receiving it with Node-RED
Projects with small embedded devices have become a lot more easy in recent years, thanks to affordable and easy Internet of Things devices and more accessible programming environments. Just one year ago I did a small, fun project with a friend after receiving a RuuviTag from Kickstarter. We measured sauna temperatures with the intention of getting an alarm when it was hot enough to enjoy. We used a Node-RED server running on a RaspberryPI device. From there we forwarded the data to the ThingSpeak service for web-based visualization. I should note that nowadays there are more visually impressive services available as well, such as Grafana. It’s open source, too.
I have done earlier projects with devices similar to Arduino and they involving a lot of C programming and soldering cables to ordinary sensor devices. They’re still available and more reliable in some sense, but for some purposes devices like RuuviTag just make everything so pain-free. You don’t always feel like wiring your apartment with new cabling and struggling with C code. Also, the visualization platforms available nowadays are just impressive.

Figure: Topic modeling -based analysis of current application areas in gamification
Gamification, or the application of game elements in non-game environments, is nowadays an increasingly popular field of research. The number of yearly publications on the topic has grown overwhelmingly. In this paper, we mapped the publication trends in gamification, and analyzed which in which fields the application of gamification is most popular. Health, play, education, crowdsourcing, and software development were identified as the most trending topics.
The paper is available at ScienceDirect. Alternatively, you can request a preprint at ResearchGate.
The term gamification and gamified systems are a trending area of research. However, gamification can indicate several different things, such as applying the game-like elements into the design of the user interface of a software, but not all gamification is necessarily associated with software products. Overall, it is unclear what different aspects are studied under the umbrella of ‘gamification’, and what is the current state of the art in the gamification research. In this paper, 1164 gamification studies are analyzed and classified based on their focus areas and the research topics to establish what the research trends in gamification are. Based on the results, e-learning and proof-of-concept studies in the ecological lifestyle and sustainability, assisting computer science studies and improving motivation are the trendiest areas of gamification research. Currently, the most common types of research are the proof-of-concept studies, and theoretical works on the different concepts and elements of gamification.

Figure: Marczewski’s (2015) Gamification User Type Hexad
Gamification is a trending topic in both research and commercial applications. However, there has been uncertainity of when and where gamification is effective, and which approaches are suitable different users and environments. Recent studies have proposed that personalization is a key and gamification is not necessarily a one-size fits all method. In this study, we have used the gamification user type hexad (Marczewski, 2015; Tondello et al., 2016), van Roy’s (2017) heuristics for effective gamification design, and Deterding’s (2015) design lenses to create an adaptive gamification system for personalized gamification. The CN2 rule induction machine learning method was used to distill the expert panel created gamification ruleset into a decision-making algorithm. The gamification algorithm matches situations and user types with specific gamification challenges.
The application domain is a computer-supported collaborative learning environment, where software engineering students work together in teams. The aim of the system is to encourage beneficial interactions along the principles of self-determination theory (Deci & Ryan, 2012).

In this paper we present an approach for personalizing gamification to the needs of each individual person. We designed the personalization for computer-supported collaborative learning environments by synthesizing three existing design frameworks: the lens of intrinsic skill atoms, gamification user type hexad and heuristics for effective design of gamification. The result of the design process is a context-aware and personalized gamification ruleset for collaborative environments. We also present a method for translating gamification rulesets to machine-readable classifier algorithm using the CN2 rule inducer and a framework for connecting the produced algorithm to collaborative software. Lastly, we present an example software for personalized gamification that was produced by applying the process presented in this paper.

Figure: Wearables Acceptance Model
Wearable devices are in the first big peak of the hype cycle. In the article “Intended use of smartwatches and pedometers in the university environment: an empirical analysis” my collague Jayden and the rest of the team investigate what motivates people to use them. We used his prototype wearable acceptance model (WAM) and partial-least squares path modeling to find causalities in people’s views and their intention to use wearables.
In this initial study we found that the following factors affect people’s decision to use wearables:
- Performance Expectancy, or the belief that the device will help the user achieve his or her daily goals.
- Social Influence, or peer pressure.
- Privacy Concerns.
- Wearability, or how the devices can be worn. By contrast, aesthetics or other physical characteristics did not affect intention to use.
Additionally, there was an interesting non-affecting factor: Effort Expectancy. Users’ beliefs about the ease of use did not have an impact on their intention to use.
The paper is available as a preprint at ResearchGate. Full paper metadata is available at ACM Digital Library.
In this work, we empirically examine factors that influence the intention to use wearables e.g. smartwatch or pedometer, in the university environment through a Wearable Acceptance Model (WAM). WAM incorporates UTAUT model and additional variables like wearable characteristics (e.g. wearability, design and physical characteristics), attitude and privacy. WAM was used with an online survey of 129 university faculty, staff and students. Further, partial least square (PLS) path modeling was applied in analysis of 14 hypotheses to validate WAM results. In accordance to WAM, wearability and attitude tend to have a direct effect on intention to use, whereas performance and effort expectancy had only a direct influence on attitude and no direct influence on usage intention. Similarly, privacy concern, social influence had a positive influence on the intention to use both directly and indirectly through attitude. However, design and physical characteristics had no effect on intention to use. This study makes a unique empirical contribution to wearable research by extending knowledge on university users’ behavior regarding wearables for well-being.

Figure: Screenshot from a Video Lecture on Gamification
In this research paper we publish our results from a longitudal study where we observed ten courses that used video instruction as a part of a course. Overall the experiences with video-based learning were positive. The video lectures were perceived to be highly useful by the students and were rated to be the most useful component of the course in a majority of the observed courses. Also, some of the tutorial videos received a lot of traffic from external sources, indicating that the videos provided additional benefit to the wider public.
The problems identified from prior research, especially the added effort and costs of video production, were not not an issue. We also found that unlike in previous literature, the video length did not affect usage patterns or student satisfaction. Previously shorter videos have been recommended, but longer and well-structured videos worked just as well.
One notable statistic is that the majority of viewers used a desktop or a laptop machine (84%), while only a fraction (14%) used mobile devices such as smartphones or tables.
See also our previous work on flipped classroom teaching method, which depends heavily on video lectures (presentation slides on flipped classroom).

Millennials have learned to seek information from the Internet whenever they need to know something and want to learn things. In this study, we present observations from several university courses with freely available online resources for the modern students. Ten different courses with video lectures were observed, often with positive outcomes and improved results compared to the previous course arrangements. Additionally, unlike in some previous literature, we observed that some issues such as the video length did not have a meaningful impact on the learning outcomes. Overall, the results indicate that videos offer excellent benefit-effort-ratio, and are an efficient way to reach the target audience: the students.
