- Push!Music is a novel mobile music listening and sharing system, where users automatically receive songs that have autonomously recommended themselves from nearby players depending on similar listening behaviour and music history. Push!Music also enables users to wirelessly send songs between each other as personal recommendations. We conducted a two-week preliminary user study of Push!Music, where a group of five friends used the application in their everyday life. We learned for example that the shared music in Push!Music became a start for social interaction and that received songs in general were highly appreciated and could be looked upon as 'treats'.

Konferensbidrag (refereegranskat)abstract
- This paper presents the result of a survey study where representing members of the disability movement in Sweden have shared their experiences of living and acting during the first year of the Covid-19-pandemic. The aim was to identify crisis communication challenges and where additional communication material and methods are needed for supporting people in going from knowledge to taking action for achieving a higher level of crisis preparedness. The paper also includes a brief summary of a literature review of previous international research on disabilities and the Covid-19 pandemic. Three categories of crisis communication challenges were identified displaying a vulnerability in society and pointing towards several important knowledge gaps that ought to be addressed in order to achieve crisis preparedness among all people. The results indicate that there is a need for additional communication materials and methods that can be appropriated to individual needs, and dialogue methods between authorities and people in order to counteract normative assumptions in crisis communication aimed at different target groups.

Lessons from the Regulation of E-scooters through the MDS Standard: Policy Lessons for Connected Vehicles
- 2023
-
Ingår i: Proceedings of the 56th Hawaii International Conference on System Sciences. - : IEEE. - 9780998133164

Konferensbidrag (refereegranskat)abstract
- Connected vehicles generate new data streams that present promising opportunities for policymakers to monitor and learn from events and behavior. To explore what we can learn from how public entities leverage ubiquitous data streams for policy development and enforcement, we draw on a case study of the standard Mobility Data Specification (MDS) and its use by cities to regulate E-scooter operators. Our findings suggest that (1) the richness of real-time data changes the speed of policy revision, (2) data access enables moving some micro-decisions to the edge, and (3) policy will be formulated as fixed or flexible with different amendment rules.

Efficient and Effective Generation of Test Cases for Pedestrian Detection - Search-based Software Testing of Baidu Apollo in SVL
- 2021

- With the growing capabilities of autonomous vehicles, there is a higher demand for sophisticated and pragmatic quality assurance approaches for machine learning-enabled systems in the automotive AI context. The use of simulation-based prototyping platforms provides the possibility for early-stage testing, enabling inexpensive testing and the ability to capture critical corner-case test scenarios. Simulation-based testing properly complements conventional on-road testing. However, due to the large space of test input parameters in these systems, the efficient generation of effective test scenarios leading to the unveiling of failures is a challenge. This paper presents a study on testing pedestrian detection and emergency braking system of the Baidu Apollo autonomous driving platform within the SVL simulator. We propose an evolutionary automated test generation technique that generates failure-revealing scenarios for Apollo in the SVL environment. Our approach models the input space using a generic and flexible data structure and benefits a multi-criteria safety-based heuristic for the objective function targeted for optimization. This paper presents the results of our proposed test generation technique in the 2021 IEEE Autonomous Driving AI Test Challenge. In order to demonstrate the efficiency and effectiveness of our approach, we also report the results from a baseline random generation technique. Our evaluation shows that the proposed evolutionary test case generator is more effective at generating failure-revealing test cases and provides higher diversity between the generated failures than the random baseline.

Towards Structured Evaluation of Deep Neural Network Supervisors
- 2019

- Deep Neural Networks (DNN) have improved the quality of several non-safety related products in the past years. However, before DNNs should be deployed to safety-critical applications, their robustness needs to be systematically analyzed. A common challenge for DNNs occurs when input is dissimilar to the training set, which might lead to high confidence predictions despite proper knowledge of the input. Several previous studies have proposed to complement DNNs with a supervisor that detects when inputs are outside the scope of the network. Most of these supervisors, however, are developed and tested for a selected scenario using a specific performance metric. In this work, we emphasize the need to assess and compare the performance of supervisors in a structured way. We present a framework constituted by four datasets organized in six test cases combined with seven evaluation metrics. The test cases provide varying complexity and include data from publicly available sources as well as a novel dataset consisting of images from simulated driving scenarios. The latter we plan to make publicly available. Our framework can be used to support DNN supervisor evaluation, which in turn could be used to motive development, validation, and deployment of DNNs in safety-critical applications.

Teaching Agile : Addressing the conflict between project delivery and application of Agile methods
- 2016
-
Ingår i: Proceedings - International Conference on Software Engineering. - New York, NY, USA : IEEE Computer Society. - 0270-5257. - 9781450341615 - 9781450342056 ; , s. 303-312

Konferensbidrag (refereegranskat)abstract
- This paper analyses the changes we have made in teaching agile methodologies, practices, and principles in four courses in order to address a specific dilemma: students need to apply agile methods in order to learn them, but when complementing our courses with applied content, we face the problem that students perceive the learning and application of agile methods as less important than delivering a finished product at the end of the course. This causes students to not apply theoretical process knowledge and therefore to not develop necessary skills associated with working with defined processes in the industry. Concretely, we report on our experience with teaching Scrum with Lego, removing formal grading requirements on the delivered product, emphasising process application in post-mortem reports, and organisational changes to support the process during supervision. These changes are analysed in the context of student satisfaction, teacher observations, and achievements of learning outcomes. We also provide an overview of the lessons learnt to help guide the design of courses on agile methodologies.

Performing a Check-in : Emerging Practices, Norms and ‘Conflicts’ in Location-Sharing Using Foursquare.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Location-sharing services have a long history in research, but have only recently become available for consumers. Most popular commercial location-sharing services differ from previous research efforts in important ways: they use manual ‘check-ins’ to pair user location with semantically named venues rather than tracking; venues are visible to all users; location is shared with a potentially very large audience; and they employ incentives. By analysis of 20 in- depth interviews with foursquare users and 47 survey responses, we gained insight into emerging social practices surrounding location-sharing. We see a shift from privacy issues and data deluge, to more performative considerations in sharing one’s location. We discuss performance aspects enabled by check-ins to public venues, and show emergent, but sometimes conflicting norms (not) to check-in.

- This paper deals with the implications of the socialness of private communication. Drawing upon ethnographic observations of first time mobile phone users in Rah, an island in Vanuatu, we revisit the debate on how the mobile phone reconfigures private and personal communication. Our observations show how the advent of the mobile phone disrupts and challenges existing practices around how private communication is managed on the island. These observations are used to open up a design space where we explore the socialness of personal, private communication. Drawing on the analysis, we discuss three directions for future thinking of mobile interaction design: (1) designing for spatial awareness; (2) designing for transience and (3) designing with temporality. We expand on these to discuss the notion of digital patina, which we argue, is an exciting topic to explore for the design of personal, social communication.

Konferensbidrag (refereegranskat)abstract
- Mobile technology has turned the traditionally collective activity of enjoying music into an often private one. New technologies such as wireless ad hoc networks have the potential to re-connect listeners who are now separated by headphones. We report on a field study of Push!Music,a novel mobile music sharing system. Push!Music allows both manual and automatic sharing of music between users through ad hoc wireless networking, and also provides a social awareness of other users nearby. The system was used by 13 subjects for three weeks. In post-study interviews, we identified four categories of results: social awareness, sharing music with friends, sharing music with strangers, andsharing automatically. Based on this, we present implications for design that can be applied not only to mobile music sharing systems, but to mobile media sharing in general: Allow division into active and passive use; enhance the awareness of who, where and when; support reciprocity; and finally, support identity and impression management.
