Examining human-centered design practice in the mobile apps era

Human-Centered Design (HCD) is a well-recognized approach to the design of interactive computing systems that supports everyday and professional lives of people. To that end, the HCD approach put central emphasis on the explicit understanding of users and context of use by involving users throughout the entire design and development process. With mobile computing, the diversity of users as well as the variety in the spatial, temporal, and social settings of the context of use has notably expanded, which affect the effort of interaction designers to understand users and context of use. The emergence of the mobile apps era in 2008 as a result of structural changes in the mobile industry and the profound enhanced capabilities of mobile devices, further intensify the embeddedness of technology in the daily life of people and the challenges that interaction designers face to cost-efficiently understand users and context of use. Supporting interaction designers in this challenge requires understanding of their existing practice, rationality, and work environment. The main objective of this dissertation is to contribute to interaction design theories by generating understanding on the HCD practice of mobile systems in the mobile apps era, as well as to explain the rationality of interaction designers in attending to users and context of use. To achieve that, a literature study is carried out, followed by a mixed-methods research that combines multiple qualitative interview studies and a quantitative questionnaire study. The dissertation contributes new insights regarding the evolving HCD practice at an important time of transition from stationary computing to mobile computing. Firstly, a gap is identified between interaction design as practiced in research and in the industry regarding the involvement of users in context; whereas the utilization of field evaluations, i.e. in real-life environments, has become more common in academic projects, interaction designers in the industry still rely, by large, on lab evaluations. Secondly, the findings indicate on new aspects that can explain this gap and the rationality of interaction designers in the industry in attending to users and context; essentially, the professional-client relationship was found to inhibit the involvement of users, while the mental distance between practitioners and users as well as the perceived innovativeness of the designed system are suggested in explaining the inclination to study users in situ. Thirdly, the research contributes the first explanatory model on the relation between the organizational context and HCD; essentially, innovation-focused organizational strategies greatly affect the cost-effective usage of data on users and context of use. Last, the findings suggest a change in the nature of HCD in the mobile apps era, at least with universal consumer systems; evidently, the central attention on the explicit understanding of users and context of use shifts from an early requirements phase and continual activities during design and development to follow-up activities. That is, the main effort to understand users is by collecting data on their actual usage of the system, either before or after the system is deployed. The findings inform both researchers and practitioners in interaction design. In particular, the dissertation suggest on action research as a useful approach to support interaction designers and further inform theories on interaction design. With regard to the interaction design practice, the dissertation highlights strategies that encourage a more cost-effective user- and context-informed interaction design process. With the continual embeddedness of computing into people’s life, e.g. with wearable devices and connected car systems, the dissertation provides a timely and valuable view on the evolving humancentered design.

GIS-based approach for optimization of onshore wind park infrastructure alignment in Finland

Wind power is a rapidly developing, low-emission form of energy production. In Fin-land, the official objective is to increase wind power capacity from the current 1 005 MW up to 3 500–4 000 MW by 2025. By the end of April 2015, the total capacity of all wind power project being planned in Finland had surpassed 11 000 MW. As the amount of projects in Finland is record high, an increasing amount of infrastructure is also being planned and constructed. Traditionally, these planning operations are conducted using manual and labor-intensive work methods that are prone to subjectivity. This study introduces a GIS-based methodology for determining optimal paths to sup-port the planning of onshore wind park infrastructure alignment in Nordanå-Lövböle wind park located on the island of Kemiönsaari in Southwest Finland. The presented methodology utilizes a least-cost path (LCP) algorithm for searching of optimal paths within a high resolution real-world terrain dataset derived from airborne lidar scannings. In addition, planning data is used to provide a realistic planning framework for the anal-ysis. In order to produce realistic results, the physiographic and planning datasets are standardized and weighted according to qualitative suitability assessments by utilizing methods and practices offered by multi-criteria evaluation (MCE). The results are pre-sented as scenarios to correspond various different planning objectives. Finally, the methodology is documented by using tools of Business Process Management (BPM). The results show that the presented methodology can be effectively used to search and identify extensive, 20 to 35 kilometers long networks of paths that correspond to certain optimization objectives in the study area. The utilization of high-resolution terrain data produces a more objective and more detailed path alignment plan. This study demon-strates that the presented methodology can be practically applied to support a wind power infrastructure alignment planning process. The six-phase structure of the method-ology allows straightforward incorporation of different optimization objectives. The methodology responds well to combining quantitative and qualitative data. Additional-ly, the careful documentation presents an example of how the methodology can be eval-uated and developed as a business process. This thesis also shows that more emphasis on the research of algorithm-based, more objective methods for the planning of infrastruc-ture alignment is desirable, as technological development has only recently started to realize the potential of these computational methods.

Personal branding on social media - The characteristics of strong personal brands in Finland

The purpose of the study is to define the characteristics of strong personal brands on social media in Finland. Personal branding as a phenomenon is no longer limited to celebrities and political leaders. The digital revolution and the change in online behavior have created the need for a deeper investigation of the characteristics of strong personal brands on social media. The work of different academics on personal branding are examined to gain a comprehensive understanding on this research topic that has gone through a revolution during the last decade. Early impression management theory is refined to include elements from more modern literature related to personal branding, brand identity management and social media to create a theoretical framework that simplifies the process of personal brand building on social media. The framework consisting of three phases clarifies the process of modern personal branding. The results of the study are presented in line with three research themes derived from the theoretical framework: the background of the brand, the brand identity management and the social media behavior and activities. Mixed methods are used in the research as means to broaden perception on the subject. The quantitative part of the study defines general characteristics concerning the most follower personal brands in Finland in three social media channels – Facebook, Instagram and Twitter. The other part of the research was conducted by single case study including two Finnish personal brands cases to provide a deeper understanding of personal branding practices of strong social media personal brands. The results of the study show that the most used social media channels differ in terms of the personal brand characteristics and personal branding activities. Due to the characteristics of the channels also the post activities of the personal brands differ quite significantly. It can be also inferred that there is a difference between brands with an existing offline awareness and the brands with no awareness before joining the social media. In order to reduce the gap between the ideal brand image and the current image, the brand should have a clear vision as well as a good understanding of the target group and the value it creates for its target audience. The brand identity needs to be managed by communicating with the target audience authentically in the right channels, with relevant content. The dedication, the target group’s behavior and the ability to create valuable and relevant content determines the right tactics for social media personal branding.  

The role of public export promotion in Finland Industry view of public export promotion in Southwest Finland

The role of the public export promotion in Finland needed more research. The part of the public sector export promotion in the overall export is significant. In an ever more global world not only the companies but also the counties compete against each other and the governments have an interest to boost their economy as much as they are able to. Every industrialized country has export promotion services in some form or another. In the 21st century the tendency has been the bundling of the services and this has also been done in Finland with Team Finland. The role and the efficiency of the services provided deserve more research. The research question of this study is: What is the role of the public export promotion services in Finland? The question is researched primary by expert interviews conducted for this study. The situation in Southwest Finland is studied from the viewpoint of the companies of the region by conducting a survey aimed to the successfully internationalized companies of the region and asking them on their views on the impact and role of public export services in their internationalization. The theory base is formed out of various export promotion studies, studies monitoring the effects of the promotion and theories of the internationalization process of companies. The primary material for the study are the three expert interviews conducted and the answers to the survey conducted. The research method in the first part is a constructive qualitative research. The research approach in the second part, where the views of the companies in Southwest Finland are studied, is quantitative. The study findings from the expert interviews: the aligning of the public export promotion done in Finland to the previous research and the addition of the role of the public sector in classical frameworks. The study findings from the survey: the utilizing of the public export promotion services is heavily delayed and the internationalizing companies start to utilize the services very late in their internationalization process, the average being 10,3 years from the beginning of the internationalization. Another central finding from the survey is that the successfully internationalized companies see the public export promotion services generally as highly beneficial but in the light of the answers the effect on their own company is not as significant. Concluding can be stated that the public export promotion is seen as beneficial, but the monitoring of the efficiency is complicated in the case of services. Getting the companies to start utilizing the services earlier in their internationalization needs attention from the service providers. By communicating the achieved results and benefits better to the potential users of the services the internationalization process of the companies could be accelerated
