Aufgrund der §§ 2 Abs. 4 S. 2, 16 Abs. 1 des Gesetzes über die Hochschulen des Landes Nordrhein-Westfalen (Hochschulgesetz - HG) vom 16.09.2014 (GV. NRW. S. 547) in der aktuell gültigen Fassung hat die Hochschule Düsseldorf die folgende Richtlinie erlassen.
Ausgefertigt aufgrund des Beschlusses des Präsidiums der Hochschule Düsseldorf am 30.08.2023.
Düsseldorf, den 25.09.2023
Aufgrund des § 31 Abs. 2 der Verordnung betreffend die digitale Lehre sowie betreffend die Durchführung online gestützter Wahlen der Hochschulen und der Studierendenschaften (Hochschul-Digitalverordnung – HDVO) vom 22.09.2023 (GV. NRW. S. 1116) hat das Präsidium der Hochschule Düsseldorf folgende Übergangsbestimmungen für das Wintersemester 2023/24 erlassen.
Over the past decades, research in room acoustics has established several derivative measures of an impulse response, some of which are incorporated in the ISO 3382 standards. These parameters intend to represent perceptual qualities, but were developed without a consistent modeling of room acoustical perception. More recent research proposed comprehensive inventories of room acoustic perception that are purely based on evaluations by human subjects, such as the Room Acoustical Quality Index (RAQI). In this work RA-QI scores acquired for 70 room impulse responses were predicted from room acoustical parameters. Except for Reverberance, the prediction of RAQI factors performed rather poor. In most cases, the sound source had a greater impact on RAQI scores. All analyses are published in an online tool, where users can upload omnidirectional and binaural impulse responses, and instantly obtain and visualize several physical descriptors, as well as predicted RAQI scores for three different sound sources. So far, acceptable prediction accuracy is achieved for Reverberance, Strength, Irregular Decay, Clarity and Intimacy. Larger data sets of evaluated impulse responses are required to improve the model performance and enable reliable predictions of room acoustical quality. Therefore, the administration of RAQI evaluations within the website is currently being developed.
Das vom Bundesministerium für Bildung und Forschung geförderte Forschungsprojekt IZESO untersucht vielschichtige Formen des zivilgesellschaftlichen Engagements im Alltag, Zugänge zu Engagement und institutionelle Blockierungen und Barrieren. Im Zuge einer ethnografischen Feldforschung wurde ein paradigmatisches Modell sozialräumlichen Engagements entwickelt. Es stellt Engagementprofile dar und bezieht intervenierende Bedingungen auf der Mikro-, Meso- und Makroeben ein. Hierdurch lassen sich Zugänge zu und Ausschlüsse von spezifischen Engagementformen identifizieren.
Despite the higher uptake of digital media also in older age groups, there are still challenges for people of high ages and with cognitive or motoric problems, which prevent them from learning and using devices like smartphones or tablets. Tangible user interfaces provide an opportunity to connect these people to social media, thereby increasing their digital participation in society and reducing loneliness. In this paper, we discuss the challenges of intergenerational communication and research the opportunities affiliated with tangible technologies to overcome technology barriers for adults of high ages. We present a hybrid system for social media interactions between young smartphone users and their old relatives, who do not use mobile technologies. The system consists of a tangible user interface designed specifically for old adults that connects to a standard mobile messenger service. TAMI was designed in a user-centered process to fulfill the needs of older adults and tested in a longer-term field study with pairs of young and old relatives.
User-centered and Participatory Design approaches have become widespread within HCI, also when designing digital media for older adults. These methodologies are seen as crucial to adapt technology design to older people's needs and increase their acceptance of digital technology. Nevertheless, it is often difficult to reach a diverse group of older people, for instance, people with limited technology skills, limited mobility, or cognitive issues. In addition, gerontologists criticized lately how older people's participation unfolds in technology design projects, e.g. that people are pushed into the role of users. Little is known about the motivations and needs of older adults regarding their participation in HCI research. To close this gap, we conducted an online survey (N=46) and semi-structured interviews (N=8) focusing on motivations, willingness and experiences regarding participation. Results show that people are generally willing to participate due to interest in the topic, learning new things and social bonding. However, despite the conceptions within HCI that long-term engagement is crucial within participatory design, older people in the study preferred less commitment and more open formats.
