- In this paper, a study on sonification of manual wheelchair movements is presented. The aim was to contribute to both rehabilitation contexts and in wheelchair sports contexts, by providing meaningful auditory feedback for training of manual wheelchair operation. A mapping approach was used where key parameters of manual wheelchair maneuvering were directly mapped to different sound models. The system was evaluated with a qualitative approach in experiments. The results indicate that there is promise in utilizing sonification for training of manual wheelchair operation but that the approach of direct sonification, as opposed to sonification of the deviation from a predefined goal, was not fully successful. Participants reported that there was a clear connection between their wheelchair operation and the auditory feedback, which indicates the possibility of using the system in some, but not all, wheelchair training contexts.

Design Considerations for Short Alerts and Notification Sounds in a Retail Environment

- The design and noticeability of alert sounds have been widely researched and reported, and not least, notification sounds are ubiquitous in both software and hardware product development. In an ongoing research project concerning the retail industry, we aim at designing short alert sounds that only grab attention from one group of customers, while others do not register the alerts: this particular aspect has to our knowledge not yet been studied. To establish design guidelines for such alert sounds, we conducted an experiment where test subjects would experience ordinary shopping activity including background music and an ambient soundscape in a virtual reality clothing store, but with added alert sounds. We tested, specifically, six differently designed sound alerts belonging to two classes: contextual-specific congruent sounds, and incongruent sounds that did not fit the sonic context. The results disproved our assumptions that incongruent sounds would outperform the congruent and thus in the context more anticipated sounds. The findings suggest that alert sounds can be designed with subtlety and still be noticeable and that customers will not necessarily be annoyed. We present here a first approach towards design guidelines for short alert sounds in a shop environment. Copyright: © 2021 the Authors.

Playing the design : Creating soundscapes through playful interaction

- This study takes inspiration from provocative design methods to gain knowledge on sound preferences regarding future vehicles’ designed sounds. A particular population subset was a triggering component of this study: people with hearing impairments. To that aim, we have developed a public installation in which to test a hypothetical futuristic city square. It includes three electrical vehicles whose sound can be designed by the visitor. The interface allows the user to interact and play with a number of provided sonic textures within a real-time web application, thus “playing” the design. This opens a design space of three distinct sounds that are mixed into an overall soundscape presented in a multichannel immersive environment. The paper describes the design processes involved.

The acoustics and performance of DJ scratching, Analysis and modelling
- 2010
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis focuses on the analysis and modeling of scratching, in other words, the DJ (disk jockey) practice of using the turntable as a musical instrument. There has been experimental use of turntables as musical instruments since their invention, but the use is now mainly ascribed to the musical genre hip-hop and the playing style known as scratching. Scratching has developed to become a skillful instrument-playing practice with complex musical output performed by DJs. The impact on popular music culture has been significant, and for many, the DJ set-up of turntables and a mixer is now a natural instrument choice for undertaking a creative music activity. Six papers are included in this thesis, where the first three approach the acoustics and performance of scratching, and the second three approach scratch modeling and the DJ interface. Additional studies included here expand on the scope of the papers. For the acoustics and performance studies, DJs were recorded playing both demonstrations of standard performance techniques, and expressive performances on sensor-equipped instruments. Analysis of the data revealed that there are both differences and commonalities in playing strategies between musicians, and between expressive intentions. One characteristic feature of scratching is the range of standard playing techniques, but in performances it seems DJs vary the combination of playing techniques more than the rendering of these techniques. The third study describes some of the acoustic parameters of typical scratch improvisations and looks at which musical parameters are typically used for expressive performances. Extracted acoustic and performance parameters from the data show the functional ranges within which DJs normally play. Unlike traditional musical instruments, the equipment used for scratching was not intended to be used for creating music. The interface studies focus on traditional as well as new interfaces for DJs, where parameter mappings between input gestures and output signal are described. Standard performance techniques have been modeled in software called Skipproof, based on results from the first papers. Skipproof was used for testing other types of controllers than turntables, where complex DJ gestures could be manipulated using simplified control actions, enabling even non-experts to play expressively within the stylistic boundaries of DJ scratching. The last paper describes an experiment of using an existing hardware platform, the Reactable, to help designing and prototyping the interaction between different sound models and instrument interfaces, including scratching and Skipproof. In addition to the included papers, studies were conducted of expressivity, description of the emotional contents of scratching, DJ playing activities, and the coupling between playing techniques and sample. The physical affordances of the turntable, mixer and samples, as well as genre conventions of hip-hop, are assumed to explain some of the findings that distinguish scratching from other instrumental sounds or practices.

Creating digital musical instruments with and for children: Including vocal sketching as a method for engaging in codesign

Tidskriftsartikel (refereegranskat)abstract
- A class of master of science students and a group of preschool children codesigned new digital musical instruments based on workshop interviews involving vocal sketching, a method for imitating and portraying sounds. The aim of the study was to explore how the students and children would approach vocal sketching as one of several design methods. The children described musical instruments to the students using vocal sketching and other modalities (verbal, drawing, gestures). The resulting instruments built by the students were showcased at the Swedish Museum of Performing Arts in Stockholm. Although all the children tried vocal sketching during preparatory tasks, few employed the method during the workshop. However, the instruments seemed to meet the children’s expectations. Consequently, even though the vocal sketching method alone provided few design directives in the given context, we suggest that vocal sketching, under favorable circumstances, can be an engaging component that complements other modalities in codesign involving children.
