This paper introduces an augmented reality application, AR PATIO, which was developed for an existing user involvement tool that is a part of a living lab. Augmented reality contents can be projected on-site to visualize change in a comprehensible and visual way. The aim of our application is to provide new methods for involving citizens in the innovation, co-creation, and evaluation of services and products in a living lab context. Our solution gives users the possibility to express their reactions by leaving location-based comments and feedback when using augmented reality. AR PATIO was evaluated as a part of a bigger user-experience study in which virtual reality and mobile clients were also tested. However, in this paper, we focus on the results from an AR use case. According to our UX study with 14 participants, AR PATIO created a positive experience. It was regarded as empowering, playful, innovative, and useful.

The Panama Papers is a collection of 11.5 million leaked records that contain information for more than 214,488 offshore entities. This collection is growing rapidly as more leaked records become available online. In this paper, we present a work in progress on a web browser plugin that detects company names from the Panama Papers and alerts the user by means of unobtrusive visual cues. We matched a random sample of company names from the Public Works and Government Services Canada registry against the Panama Papers using three different string matching techniques. Monge-Elkan is found to provide the best matching results but at increased computational cost. Levenshtein-based approach is found to provide the best tradeoff between matching and computational cost, while Jacquard index like approach is found to be less sensitive to slight textual change.

The internet of things (IoT) application domain is evolving continuously and is expected to bring digitalization making everything smart. This paper presents reference architecture for IoT system. Moreover, full implementation of such architecture is demonstrated with the IoT testbed deployed at the University of Oulu. Leveraging MQTT protocol, LoRaWAN is utilized as an IoT enabler technology for our platform, comprising a cloud server as well. In addition, a hybrid server is added to the platform to enable enhanced performance and functionality. To showcase the potential impacts of augmented reality (AR) based applications in an IoT infrastructure, we implemented and tested the maintenance support application. The implemented application visualizes environmental conditions and the sensor node itself as an augmented object on a mobile phone. A user study is carried out to discuss and showcase the potential impacts of using such a visualization approach.
