Communicating Semantic Content to Persons with Deafblindness by Haptograms and Smart Textiles : Theoretical Approach and Methodology
- 2020
-
Ingår i: International Journal on Advances in Intelligent Systems. - 1942-2679. ; 13:1&2, s. 103-113

Tidskriftsartikel (refereegranskat)abstract
- By means of a proof-of-concept prototype, which is work in progress, we adopted a multidisciplinary approach to develop a smart-textile-based communication system for use by people with deafblindness. In this system, sensor technologies and computer vision are used to detect environmental cues such as presence of obstacles, faces, objects, etc. Focusing on the communication module here, a new ontology connects visual analytics with the user to label detected semantic content about objects, persons and situations for navigation and situational awareness. Such labelled content is then translated to a haptogram vocabulary with static vs. dynamic patterns, which are mapped to the body. A haptogram denotes a tactile symbol composed over a touchscreen, its dynamic nature referring to the act of writing or drawing. A vest made of smart textile, in the current variant equipped with a 4 x 4 grid of vibrotactile actuators, is used to transmit haptograms on the user’s back. Thereby system messages of different complexity -- both alerts and short sentences -- can be received by the user, who then has the option to respond by pre-coded questions and messages. By means of grids with more actuators, displays with higher resolution can be implemented and tested, paving the way for an extended haptogram vocabulary, covering more detailed ontology content.

Konferensbidrag (refereegranskat)abstract
- Based on the ontology developed in the ongoing SUITCEYES EU-funded project to bridge visual analytics for situational awareness and navigation with semantic labelling of environmental cues, we designed a set of static and dynamic haptograms to represent concepts for two-way communication between deafblind and non-deafblind users. A haptogram corresponds to a tactile symbol drawn over a touchscreen, its dynamic nature referring to the act of writing or drawing, where the touchscreen can take several forms, including a smart textile screen designated for specific areas on the body. In its current version, our haptogram set is generated over a 4 x 4 matrix of cells and is displayed on the back of the user, tested for robustness at the receiving end. The concepts and concept sequences simulating simple questions and answers represented by haptograms are focused on ontology content for now but can be scaled up.

Academic librarianship in flux : The dynamics of negotiating professional jurisdiction
- 2022
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This study aims to better understand the dynamics of negotiating professional jurisdiction within research from the perspective of academic librarians who develop library services for researchers. This qualitative case study consists of 24 semi-structured interviews, 32 recorded non-participant observations, and seven official university library documents collected at one Swedish university library with three division libraries during 2016.The analytical frame is based on Abbott’s (1988) system of professions approach and focuses on changes in professional work. It is assumed that all professions have strong or weak control of jurisdictions, which are described as a profession’s exclusive rights to a task area, including the right to define tasks and relevant professional knowledge. The assumption is that jurisdictions change and are under constant negotiation at the workplace until settled. The settlements range from strong to weak control of jurisdiction. The analytical frame also identifies disturbances in negotiating jurisdiction that can be internal or external to a profession, e.g., new knowledge, organization, and technology.The results show that developing library services for researchers is an ambiguous and complicated task. It is influenced by several constraints and addressed differently by academic librarians. Constraints are related to the task description, organization, management support, communication, academic librarians’ skills and competencies, as well as level of ambition. The results showed that academic librarians can claim jurisdiction within research, although disciplinary differences emerged. Academic librarians at a science and medical library seemed to have more apparent opportunities than academic librarians in humanities and art history or social science libraries to claim jurisdiction within research. The study confirms that access jurisdiction is an acknowledged jurisdiction for academic librarians and is strengthened by new and emerging tasks related to access, e.g., digitization. Access jurisdiction seems to act as a springboard to claim and negotiate jurisdiction within research. The study reveals active push and passive pull dynamics related to negotiating jurisdictions and highlighted communication and information dissemination as an organizational disturbance not previously considered in Abbott's (1988) system of professions approach. In addition, the thesis clarified a need to analyze the work and needs of the profession itself.

Modeling uncertainty in bibliometrics and information retrieval : an information fusion approach
- 2015

Tidskriftsartikel (refereegranskat)abstract
- We describe ongoing research where the aim is to apply recent results from the research field of information fusion to bibliometric analysis and information retrieval. We highlight the importance of ‘uncertainty’ within information fusion and argue that this concept is crucial also for bibliometrics and information retrieval. More specifically, we elaborate on three research strategies related to uncertainty: uncertainty management methods, explanation of uncertainty and visualization of uncertainty. We exemplify our strategies to the classical problem of author name disambiguation where we show how uncertainty can be modeled explained and visualized using information fusion. We show how an information seeker can benefit from tracing increases/decreases of uncertainty in the reasoning process. We also present how such changes can be explained for the information seeker through visualization techniques, which are employed to highlight the complexity involved in the process of modeling and managing uncertainty in bibliometric analysis. Finally we argue that a further integration of information fusion approaches in the research area of bibliometrics and information retrieval may results in new and fruitful venues of research.

- Interaction and capturing information from the surrounding isdominated by vision and hearing. Haptics on the other side, widens the bandwidthand could also replace senses (sense switching) for impaired. Haptictechnologies are often limited to point-wise actuation. Here, we show thatactuation in two-dimensional matrices instead creates a richer input. Wedescribe the construction of a full-body garment for haptic communication witha distributed actuating network. The garment is divided into attachabledetachablepanels or add-ons that each can carry a two dimensional matrix ofactuating haptic elements. Each panel adds to an enhanced sensoric capability ofthe human- garment system so that together a 720° system is formed. The spatialseparation of the panels on different body locations supports semantic andtheme-wise separation of conversations conveyed by haptics. It also achievesdirectional faithfulness, which is maintaining any directional information abouta distal stimulus in the haptic input.

Konferensbidrag (refereegranskat)abstract
- The aim of this paper is to present an overview of the preliminary findings in an ongoing study conducted in MuseIT – a Horizon Europe project (Oct. 2022 – Sept. 2025) – that proposes technologies facilitating and widening access to cultural assets in an ‘inclusive way’. The paper reports on the results of a literature review and the first ideation workshop conducted in January 2023. The workshop participants were representatives of cultural institutions and users of cultural institutions, and/or consumers and producers of cultural assets, with a focus on people with disabilities. The findings indicated that digital environment is greatly appreciated by participants with disabilities for both communication with others and for self-expression. Cultural institutions are aware of the variety of needs, including the need for collaborative development of services accessible to all. There remain, however, challenges and unmet needs. To address these, there is a need to involve people with disabilities – who are experts on such needs based on lived experiences – in the design of tools and services aimed at meeting their needs. Furthermore, there is a need for improved understanding of disability and diversity of needs, in projects involved in developing technological systems to facilitate and broaden accessibility.

Interpersonal Influence in Viral Social Media: A Study of Refugee Stories on Virality
- 2017
-
Ingår i: Proceedings of the 8th International Conference on Communities and TechnologiesTable of Contents. - New York : ACM. - 9781450348546 ; , s. 183-192

Konferensbidrag (refereegranskat)abstract
- The expansion of social media use has enabled massive and rapid spreadability of content, which is often referred to as virality. Earlier studies have examined various aspects of virality such as the attributes of stories that become viral. In this on-going study we aim to make a better sense of the role of interpersonal influences in the spreadability of viral social media content. In this, we are inspired by Tarde’s views on interpersonal processes and the notion of imitation. Considering the recent mass migrations, and numerous viral stories that have related to the plight of refugees, we chose a group of Syrian refugees consisting of men and women as the participants for this study. In twelve in-depth qualitative interviews we learned about the participants’ views on viral stories as well as the way in which their interpersonal influences may play a role in their interaction with viral stories. The findings show that the views on migrant-related viral stories varied among the participants, but a common view seemed to be somewhat of scepticism about the agenda behind the spread of these stories. As part of the study, we identified four key interpersonal influences including community conversation, formative consciousness, community boundaries, and retrospective experiences. A main conclusion in the study is that although back-end technical issues, content attributes, emotions and so on may play a role in virality, still human agency, connections and interpersonal ties play a major role in shaping the process that leads to content spreadability, hence virality.
