Now-here / Nowhere: Digital Reconstruction of Personal Memories as a Virtual Reality Experience
(2024-12-31) Perez Moreno, Carlos
 School of Arts, Design and Architecture | Master's thesis
This thesis investigates how volumetric capture and 3D scanning technologies can be integrated into a Virtual Reality (VR) framework to create immersive, interactive experiences centred around personal memories. By employing techniques such as photogrammetry, Light Detection and Ranging (LiDAR) scanning, and volumetric video capture, the project aims to reconstruct the author’s autobiographical memories within a virtual environment, allowing participants to engage and interact with these recollections firsthand. Building upon theoretical foundations from memory studies, new media, and VR filmmaking, the research emphasises the significance of memory as an active, culturally influenced, and creative process. The work explores how participants can embody the author’s perspective and navigate digitally reconstructed environments through VR’s immersive capabilities and participant feedback gathered during two public exhibitions. These environments, populated with volumetric narrators and 3D-scanned spaces, challenge traditional notions of storytelling, enabling a form of “interactive remembrance” that resonates personally and culturally. By focusing on interactive VR instead of conventional cinematic VR or linear narratives, this thesis contributes to understanding how immersive media can facilitate more profound emotional engagement with memory-based content. The insights gained from experimenting with volumetric capture, photogrammetry, and LiDAR scanning offer valuable directions for future creative works and research, ultimately advancing the fields of VR narrative design and memory representation.
PORTTI 2340: Väyläestetiikka Paimion sisääntuloväylällä ja sen porttikohdassa
(2024-12-17) Aalto, Julius
 School of Arts, Design and Architecture | Master's thesis
The thesis focuses on the road and landscape architecture to enhance the Pakurla Bridge and its surrounding area in Paimio. The Pakurla Bridge and its enviroment serve as a transitional zone and gateway, marking the boundary between rural and urban area. The plan responds to Paimio’s need to develop the visual impact of the gateway along the Road 2340. The plan integrates landscape architectural solutions and artistic elements into the road design. It focuses on Road 2340, with particular emphasis on the gateway area, including a roundabout. The purpose is to create a functional and aesthetic road environment that supports Paimio’s structural transformation while highlighting its local values and identity. The theoretical framework is based on road design research, emphasizing road aesthetics and experiential qualities. The aesthetics of the road is defined by kinesthetic and visual observations, with spatial experiences emerging from the harmony between the surroundings and road structures. The framework also examines the potential of site-specific art to enhance the cultural and functional values of the road environment. To establish the design principles, Road 2340 is analyzed comprehensively through empirical observations, particularly focusing on the interaction between experiential and aesthetic factors. Based on these observations, the road is divided into segments, each with development proposals to support the gateway area’s design. The resulting concept incorporates the unique characteristics of the road and the city. The concept, ”Streamline”, integrates the Paimionjoki river and its landscapes into the area and road design. The green areas’ landform design mimics a tributary of the Paimionjoki river, creating a dynamic and kinesthetic experience for road users. A monumental land art sculpture, symbolizing the cultural significance of the Paimionjoki River as Paimio’s historical foundation, is proposed for the roundabout’s central island. This sculpture, together with surrounding greenery, forms a visually cohesive entity, blending the road’s functionality with aesthetic values. The plan aims to leave a lasting impression on road users arriving in or departing from the city.
Maantiet kaduiksi - liikenneväylät asemakaava-alueilla
(2024-12-05) Leukkunen, Elina
 School of Engineering | Master's thesis
Abstract Section 83 of the Land Use and Building Act stipulates the purposes for which roads can be designated as road traffic areas in local plans. The power of control over planning is assigned to municipalities and cities, and in addition, the administrative classification of roads from road to street is not determined by a legally binding local plan but requires the municipality to complete the administrative change by issuing a street maintenance decision and updating the land register. There is no time frame specified in the legislation for completing this whole process, and on the other hand, there is no definition of long-distance traffic in the legislation. This study examines the current legislation and its functionality from the perspective of both municipalities and economic development, transport and environmental centres, as well as what kind of changes could possibly be made to the legislation to clarify the interface between roads and streets. The study also examines how street zoning, street maintenance decisions and real estate transactions could be promoted even in situations where the municipality does not have its own need to designate a road area as a street and make an administrative decision on the matter. In addition to these themes, the operational areas of the Pirkanmaa and Uusimaa ELY Centres are compared to see how the needs for changes regarding the administrative category are manifested. The methods used in the study are legal theory and interview research. During the study, the current legislation was studied, and in addition already repealed legislation was also studied, the effects of which are still partly visible in the valid local plans. At the time of writing the master's thesis, the legislation is partly in a state of transition, as the Land Use and Building Act, which has been in force since 2000, is changing and being divided into several new different acts, which may also have effects on the interface between roads and streets in the future. The interview study was conducted as semi-structured interviews, in which representatives of both the municipalities and the Pirkanmaa ELY Centre were interviewed. As a result of the study, it was found that the possibilities for changes to the legislation are ultimately quite limited, and the main means of coordinating the views of the ELY Centre and the municipalities is primarily cooperation between the authorities.
Integrating cotemporally acquired multibeam echosounder and mobile LiDAR data
(2024-12-24) Häkkilä, Heikki
 School of Engineering | Master's thesis
This study explores the integration of cotemporally acquired 3D point cloud data from multibeam echosounder and mobile laser scanning systems. As both are kinematic mapping techniques, also the key concepts of satellite positioning and inertial navigation were reviewed in the literature view. For the empirical part, Riegl VMQ-1 mobile laser scanner and Teledyne SeaBat T20-P multibeam echosounder were mounted on the survey vessel. The data was collected cotemporally in the Southwest coast of Finland. The first phase was the orientation calibration of the SeaBat T20-P multibeam echosounder. The system was calibrated using a sonar patch test at a designated site, yielding orientation offsets of -0.14° for roll, +0.20° for pitch, and +0.25° for yaw. After the calibration, the height position of the sonar data was compared to the reference surveys made at the site. Sub 4 cm accuracy for the height component was achieved in relation to the reference measurements. While the integration process of sensor data produced promising results, the external accuracy analysis of the mobile laser scanning point cloud showed relatively large and consistent error compared to the reference points. The RMSE of the error residuals for XY and Z components were over 5 cm. Much lower standard deviation values (1.11 cm for XY and 1.30 cm for Z) indicated that the internal accuracy of the point cloud was superior to the external one. Examining the mutual alignment of the multibeam echosounder and mobile laser scanning data turned out to be challenging, as there was roughly 1 m vertical gap between the point clouds and not many suitable objects with well recognizable above ground and submerged parts. Based on the visual inspections and manual measurements taken from the point clouds, the multibeam echosounder and mobile laser scanning point clouds were aligned with an accuracy of under 5 cm.
Supporting Inclusion Experience in Participatory Budgeting: Case Vantaa
(2024-12-18) Taira, Kazuichiro
 School of Engineering | Master's thesis
Adaptations of participatory budgeting (PB) are place-based conditions since regulation and promotion for the deployment of PB can happen in any layer of governance, from municipality to national in the theories. Often, cases of PB adaptation in the EU happen on a municipal scale. Development of PB is moving forward on the online platform while it seems to be hybrid methods (online and offline) of participation, to keep attracting potential participants and hold an open space for discussions across government representatives, interest groups, private entities, and ordinary individuals. Finnish major cities have been piloting PB in different ways (targeting specific districts, themes, social group, or city-wide scale of PB). The city of Vantaa has paid attention to PB and deployed small pilot PB projects in seven districts, which are seen as clusters of socio-economically vulnerable residents. The city has tended to use PB as a part of community engagement and development tools to exchange ideas and opinions within those districts. The aim of the thesis was to investigate the current challenges associated with online and offline participation methods with experience of social inclusion aspects also cross-examine the overall of PB (generation to deployment also one cycle of PB process) to provide recommendations for solving these challenges, then materializing the connection between PB and relevant frameworks at the city. This was conducted by using findings from relevant study fields, published documents, three surveys, and information collected from 15 interviewees. As the research on PB is transdisciplinary and discuss divers aspects, this these establish linkage between PB development from global to Finnish contexts, focused on social inclusion and online and offline meetings. The research on the PB has been approached in divers academic domaines. In this thesis, literature review of the theme focused political science, management science, urban planning, and technology. Ambiguity of PB in the academic field must be noted here. So that, the baseline of monitoring or evaluation of PB must be place-based and context specific. Thus, the methods used in this thesis are surveys and interviews. Three series of survey data were shown collective residents perspectives in the general aspects of the city’s affair which included the PB projects. The main survey analysis was conducted based on the Experience of Social Inclusion Scales (ESIS). Internal and external interviews, in which individuals who have being facilitator of PB and have being resident of Vantaa. Mapping relations between PB and relevant documents, as well as result of internal interview established the importance of coordination in the strategic use of PB. The result latest general ESIS mean scores showed 79.6 and the mean score has been gradually in growing trend from 2020. In the latest survey with an analysis of the ESIS mean score by socio-demographics, which pointed out that survey respondents in youngest age groups and negative healthconditions shown their ESIS mean scores lower than the general ESIS mean score. ESIS mean scores from respondetns with foreign backgrounds by mother tongue and birthplace, which shown slightly higher ESIS mean score than the general ESIS mean. But, the survey respondents with foreign background were less represented in collection of survey to general populations. Thus, external interviews result shown the potential challenges in language barrier in onsite meetings. This described the need of affirmative use of alternative PB central body as existing civic council (influencing bodies) to promote social inclusion, also quality participation and increase of participants, when the PB in Vantaa further considered to deploy in the future.
