Competing or Aligning? Assessment for Telecom Operator's strategy to address OTT TV/Video services
- 2012
-
Konferensbidrag (refereegranskat)abstract
- Up until recently, it was rarely direct competition between telecom operators, cable and satellite Pay-TV providers in digital TV/Video, as their business area were different and value chain was well established. However, technology advance has altered digital TV/Video landscape, made these Communication Service Providers (CSPs) cross other’s area and opened door for new actor (OTT player) to enter the market. This triggers second change in the landscape, as it potentially bypasses CSP’s role in digital media value chain.There are generic potential options for telecom operator to address OTT service‘s treat, where the trend shows gradual shifts toward allowing or promoting. This study assesses telecom operator’s reaction strategies to react to this digital TV/Video convergence trend. Our analysis reveals two typical relation patterns in the value network, used by telecom operators based on strategy options above, which are ”point-to-point” and ”point-to-multipoint” relation model. We explore the underlining motivations that based these strategies, as well as analysis of the eco-systems: actors identification, business roles and distributed responsibilities among them, where we use ARA (Actors, Resource, Activities) point of view to model these value networks.

Mobile music business models in Asia’s emerging markets

Konferensbidrag (refereegranskat)abstract
- In the telecom business, there has been a heavy competition from Internet, media and handset vendors companies. These over-the-top (OTT) players offer compiling telecom services, cause a transformation in the telecom business ecosystem, and the most challenging services posed here are media services. China, India and Indonesia, as world’s emerging markets in Asia, are predicted to take the largest share in the global mobile traffic explosion by 2015. It is critical for mobile network operators (MNOs) in this region to explore strategy for mobile media services, as mobile broadband is likely preferred compared to fixed broadband. In this paper, we analyze and compare mobile music business models used in these markets and structure the relation models between the key actors, using Actors, Relations and Business Activities (ARA) model. We present the economic models that are emerging, and an insight of why and how these multitudes actors are betting on currently. We found that the MNOs generally have a much stronger position compared to their counterparts in the developed markets, and the personalization services, like ring-back tone, are still a huge success. The actors tend to deliver the services by their own, rather than to collaborate in a horizontal business setting.

Being and mixing : designing interactive soundscapes
- 2006
-
Ingår i: Proceedings of the 4th Nordic conference on Human-computer interaction. - New York, NY, USA : ACM. ; , s. 252-261
-
Konferensbidrag (refereegranskat)abstract
- This paper describes a study of the auditory environment in a chemical factory, and how a group of process operators ascribe meaning to a selection of sound clips from their daily work environment. We argue for a design-oriented phenomenological approach to soundscape studies, and suggest an approach based on an exploration of how already occurring sounds are used. This knowledge will be used to inform the design of new useful auditory environments. Our study shows that the richness of the auditory environment is a crucial aspect of the distributed work environment. An important part of the design process is the operator’s contribution to the concepts suggested. From design workshops several design concepts aiming to explore and test different approaches for making sound affordances available have been developed. This has led us to a new understanding of how interactive soundscapes enable distributed awareness – what we refer to as ’Being and Mixing’.

Energy Saving Approaches for Video Streaming on Smartphone based on QoE Modeling
- 2016

Ingår i: 2016 13TH IEEE ANNUAL CONSUMER COMMUNICATIONS & NETWORKING CONFERENCE (CCNC). - : Institute of Electrical and Electronics Engineers (IEEE). - 9781467392921

Konferensbidrag (refereegranskat)abstract
- In this paper, we study the influence of video stalling on QoE. We provide QoE models that are obtained in realistic scenarios on the smartphone, and provide energy-saving approaches for smartphone by leveraging the proposed QoE models in relation to energy. Results show that approximately 5J is saved in a 3 minutes video clip with an acceptable Mean Opinion Score (MOS) level when the video frames are skipped. If the video frames are not skipped, then it is suggested to avoid freezes during a video stream as the freezes highly increase the energy waste on the smartphones.

Designing From Data : A Case Study From the Health Mashups Service
- 2013
-
Ingår i: Workshop on Informing Future Design via Large-Scale Research Methods and Big Data.
-
Konferensbidrag (refereegranskat)abstract
- Instrumentation of mobile service interactions now allows for the ability to understand use in new ways and to base the design of system iterations as well as future services on data obtained from use “in the wild”over extended periods of time. This position paper will detail a few specific instances in the Health Mashupsproject where we were able to use usage data to improve the design and to create design implications to increase engagement in new services.

Health Mashups : Presenting Statistical Patterns between Wellbeing Data and Context in Natural Language to Promote Behavior Change

- People now have access to many sources of data about their health and wellbeing. Yet, most people cannot wade through all of this data to answer basic questions about their long-term wellbeing: Do I gain weight when I have busy days? Do I walk more when I work in the city? Do I sleep better on nights after I work out? We built the Health Mashups system to identify connections that are significant over time between weight, sleep, step count, calendar data, location, weather, pain, food intake, and mood. These significant observations are displayed in a mobile application using natural language, for example, "You are happier on days when you sleep more." We performed a pilot study, made improvements to the system, and then conducted a 90-day trial with 60 diverse participants, learning that interactions between wellbeing and context are highly individual and that our system supported an increased self-understanding that lead to focused behavior changes.

Perceptive presence

Ingår i: IEEE Computer Graphics and Applications. - 0272-1716 .- 1558-1756. ; 23, s. 26-36

Tidskriftsartikel (refereegranskat)abstract
- Perceptive presence systems automatically convey awareness of user states to a remote location or application without the user having to perform explicit commands or mode selection. The article describes a component-based architecture for creating presence applications using perceptual user interface widgets. Each widget performs a machine perception function, such as tracking a face or monitoring activity in a specific 3D location. Widgets provide an abstraction barrier between the perception algorithms and the needs of application writers. Two example applications developed using this framework are presented: one uses a luminous display to express a user’s availability for communication to a colleague at a remote location, and a second uses activity to control devices in a context-aware environment.

The power of mobile notifications to increase wellbeing logging behavior
- 2013
-
Ingår i: CHI '13 Proceedings of the SIGCHI Conference on Human Factors in Computing Systems. - New York, NY, USA : ACM Digital Library. - 9781450318990 ; , s. 1095-1098

Konferensbidrag (refereegranskat)abstract
- Self-logging is a critical component to many wellbeing systems. However, self-logging often is difficult to sustain at regular intervals over many weeks. We demonstrate the power of passive mobile notifications to increase logging of wellbeing data, particularly food intake, in a mobile health service. Adding notifications increased the frequency of logging from 12% in a one-month, ten-user pilot study without reminders to 63% in the full 60-user study with reminders included. We will discuss the benefits of passive notifications over existing interruptive methods.
