Tidskriftsartikel (refereegranskat)abstract
- This case study is based on a research through design project (RTD) that focuses on a technical communication video of the live-action format. It investigates the usability and design-implications of a live-action how-to video, by means of analyzing user-centered data such as YouTube analytics data, usability, and comprehension assessments. In the study, four key live-action video affordances are identified: verifiability, comparability, recordability, and visibility. The identification of these affordances when related to the users’ assessments resulted in several design implementations that would warrant sought-for communication efficacies. Findings show that some assumed efficacies appear to be mitigated by the complexity and the density of the video information. One implication of this is that the implementation of conventional video editing techniques and the addition of on-screen text that serve to make content briefer and more concise into instructional live-action videos requires the technical communicator’s careful consideration.

- This pilot study aims at illuminating human visual behavior in the interaction with pictorial instructions. The study is a multi disciplinary effort and is informed by the connection between gaze and attention as well as certain aspects of the Visual Literacy field and reveals a few basic visual behavior tendencies related to certain specific pictorial instruction types. By doing so, it is also an evaluation of the usefulness of a methodological framework consisting of six measures.The analysis of this paper is primarily based on eye-tracking data. In addition, an observed assembly that generated video and sound recordings is also part of the method. In the study 12 Film/TV- production students (out of which there is complete data from 9 informants) interacted with three types of types of visual instructions of the same assembled object, a solar powered toy.

New design process models for the audio visual industry : a design science approach
- 2010

Ingår i: DS 60: Proceedings of DESIGN 2010, the 11th International Design Conference, Dubrovnik, Croatia. - Dubrovnik : FSB-The Design Society. - 9789537738037 ; , s. 223-232

Konferensbidrag (refereegranskat)abstract
- Industrial design processes have several common denominators regardless of the actual design. This is to say that the production of moving images is a kind of design process. Even though every single film- or TV-production is unique, the production processes as such are often similar. Therefore we suggest that a Distributed Creativity Workflow Model will be useful in film- and TV-production. This model will facilitate the design process and make the production of contemporary audio-visual material more cost effective. Hopefully more time can be spent on creativity within the process.

- Abstract: This article will address the question of how fiction films are individuated in terms of image quality on the grounds of the recording technology used. As new cost-effective digital recording technologies are introduced to the marketplace, this becomes a salient issue to understand for producers and production teams. In order to define cameras’ image quality capacities, three almost identical short fiction film sequences were tested on a young audience in a comparative blind test. Surprisingly, the result unambiguously showed that most viewers preferred the film recorded on an iPhone. Based on Barbara Maria Stafford's theoretical framework on the cognitive work of images and theories that concern ecological moving image theory, the analysis of this article aims to explain the reception study's result by illuminating the sublime and ambiguous figure–ground constellation of the iPhone video and its cognitive ramifications.

Videography as Design Nexus : Critical Inquires into the Affordances and Efficacies of Live-action Video Instructions
- 2018
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis is about live-action instructional videos (LAVs). By addressing design problems with respect to the how-to video genre, the thesis asks fundamental questions about mediated instructional communication efficacies and the factors that either obstruct or augment them. The analysis presented in this thesis is based on the notion that videography is a design nexus and key focal point of the connections that make live-action video instructional efforts possible. This Design Nexus is explored by defining and illuminating key ontological dimensions, medium specificities and the video users’ cognitive capacities. This is to acknowledge that the users of instructions in this thesis are center stage, both as biological and cultural beings.The methods used in this thesis and its associated papers are eye-tracking, video observations, questionnaires, self-reports, focus group interviews and YouTube analytics. Hence, both numerical data and non-numerical data are analyzed in this study.The results of the analyses indicate that pre-production planning is key in live-action video instructional endeavors, but not at the expense of the videographer’s status as designer. Moreover, the analyses show that users’ cognitive processing and visual decoding depend on the power of the live-action format to show actual human behavior and action. Other presented evidence seems to infer that LAV-instructions are a little less demanding if users apply a focused decoding style when interacting with them. Nevertheless, physiological engagement of this kind is likely not to fully compensate for users’ psychological engagement.This thesis contributes to a more comprehensive understanding of humans’ abilities to interpret the actions of others via medial means. By relating this to video medium-specific affordances, this thesis also furthers important efficacy distinctions and boundary conditions. This understanding is considered important for live-action video makers and designers of visual instructions as well as scholars who need to develop better methods to assess users’ behavioral engagement when they interact with digital instructional media.

Videography as production nexus : digital film cameras, media mangement and the distribution of creativity
- 2013
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis is about new digital moving image recording technologies and how they augment the distribution of creativity and the flexibility in moving image production systems, but also impose constraints on how images flow through the production system. The central concept developed in this thesis is ‘creative space’ which links quality and efficiency in moving image production to time for creative work, capacity of digital tools, user skills and the constitution of digital moving image material. The empirical evidence of this thesis is primarily based on semi-structured interviews conducted with Swedish film and TV production representatives.This thesis highlights the importance of pre-production technical planning and proposes a design management support tool (MI-FLOW) as a way to leverage functional workflows that is a prerequisite for efficient and cost effective moving image production.

Tidskriftsartikel (refereegranskat)abstract
- A new ternary Ir-Mn-Si phase with stoichiometry Mn3IrSi has been synthesized and found to crystallize in the cubic AlAu4-type structure, space group P213 with Z=4, which is an ordered form of the β-Mn structure. The unit cell dimension was determined by x-ray powder diffraction to a=6.4973(3)Å. In addition to the crystal structure, we have determined the magnetic structure and properties using superconducting quantum interference device magnetometry and Rietveld refinements of neutron powder diffraction data. A complex noncollinear magnetic structure is found, with magnetic moments of 2.97(4)μB at 10 K only on the Mn atoms. The crystal structure consists of a triangular network built up by Mn atoms, on which the moments are rotated 120° around the triangle axes. The magnetic unit cell is the same as the crystallographic and carries no net magnetic moment. The Néel temperature was determined to be 210 K. A first-principles study, based on density functional theory in a general noncollinear formulation, reproduces the experimental results with good agreement. The observed magnetic structure is argued to be the result of frustration of antiferromagnetic couplings by the triangular geometry.

Tidskriftsartikel (refereegranskat)abstract
- A new phase in the ternary Ir–Mn–Si system has been synthesised. From powder neutron diffraction data the crystal structure was determined to be of the AlAu4 type and to be described in the cubic space group P213 with the unit cell a=6.4973(3) Å. Susceptibility measurements using a SQUID-magnetometer showed a transition typical of antiferromagnetism, with TN=210 K. Low temperature antiferromagnetic order is confirmed by extra peaks in neutron diffractograms recorded at 10 and 80 K.

Cycloidal magnetic order in the compound IrMnSi
- 2005

Tidskriftsartikel (refereegranskat)abstract
- A new compound, IrMnSi, has been synthesized, and its crystal structure and magnetic properties have been investigated by means of neutron powder diffraction, magnetization measurements, and first-principles theory. The crystal structure is found to be of the TiNiSi type (ordered Co2P, space groupPnma). The Mn-projected electronic states are situated at the Fermi level, giving rise to metallic binding, whereas a certain degree of covalent character is observed for the chemical bond between the Ir and Si atoms. A cycloidal, i.e., noncollinear, magnetic structure was observed below 460 K, with the propagation vector q=[0,0,0.4530(5)] at 10 K. The magnetism is dominated by large moments on the Mn sites, 3.8μB∕atom from neutron diffraction. First-principles theory reproduces the propagation vector of the experimental magnetic structure as well as the angles between the Mn moments. The calculations further result in a magnetic moment of 3.2μB for the Mn atoms, whereas the Ir and Si moments are negligible, in agreement with observations. A calculation that more directly incorporates electron-electron interactions improves the agreement between the theoretical and experimental magnetic moments. A band mechanism is suggested to explain the observed magnetic order.
