3D thumbnails for mobile media browser interface with autostereoscopic displays
(Springer, 2010-01) Gündoğdu, R. Bertan; Yiğit, Yeliz; Çapin, Tolga
In this paper, we focus on the problem of how to visualize and browse 3D videos and 3D images in a media browser application, running on a 3D-enabled mobile device with an autostereoscopic display. We propose a 3D thumbnail representation format and an algorithm for automatic 3D thumbnail generation from a 3D video + depth content. Then, we present different 3D user interface layout schemes for 3D thumbnails, and discuss these layouts with the focus on their usability and ergonomics. © 2010 Springer-Verlag Berlin Heidelberg.

The aid of colour on spatial navigation: A study in a virtual hospital environment
(ACM, 2016) Kumaoğlu, Özge; Olguntürk, Nilgün
The aim of this study is to explore the effects of colour as visuo-spatial cue on spatial navigation and developing a cognitive map in elderly in a simulated virtual hospital environment. The study further purports to explore whether it is possible to improve elders' spatial navigation and cognitive mapping performances as well as younger-aged group, by the aid of coloured visuo-spatial cues. © 2016 ACM.

Building empathy in interior architecture education: exploring empathic design and its reflections
(2023-03) Yeşiltepe, Melis
Integrating empathy to design education enhances students' universal design solutions since empathic design provides a feeling and understanding of a wide range of users' needs in the designed environment or products. This study investigates how using empathic design techniques as instructional design methods influence students’ improvement in the multiple dimensions of empathy, design process and end products, and perceptions of their learning experience. The empirical research is conducted with three groups and a control group who are asked to experience different empathic design techniques (direct contact between designers and users, indirect contact between designers and users, and role-playing) obtaining in the redesign of an existing kitchen and reflecting their learning and design outcomes on an online session in virtual meetings. Qualitative data collection methods consist of behavioral observations, the researcher's logbook, interviews, and design conversation protocols obtained by video recordings of the Zoom meetings. Quantitative data collection methods include using a questionnaire and survey as instruments and assessment of end products. Thematic analysis was conducted to study data from interviews and design. Results indicated that an empathic design process positively indicated students' perceptions of their learning experience and enhanced their self-awareness and design awareness. In addition, empathic design improved students' problem-solving skills, helped them attain universal design solutions easily, and shortened the design process time. The role-playing technique was the most efficient compared to other techniques for raising students' empathy and proposing universal design solutions.

Design considerations in multipurpose space of preschool educational environments
(1994) Özyurt, Elçin
Design requirements of preschool educational environments that support all aspects of child development are examined in this study. In order to determine the design criteria for preschool educational environments, the characteristics and the properties of early childhood are investigated. Additionally, educational philosophy and psychological influences of environment which affect the physical organization are stated. Within this framework, design considerations of preschool educational environments are discussed under the issues of activity places, alternative organizations, and items of furniture which build up the environment. Finally, general design criteria which are necessary for a comfortable education environment are pointed out.

Multisensory inclusive design education: a 3D experience
(Routledge, 2017-09-19) Altay, Burçak
Inclusive design should be an integral part of the curriculum in the education of environmental design disciplines, incorporating empathic understanding. Among the empathic methods that are employed, ‘build-to-learn’ that promotes experiential learning is effective in students’ multisensory and bodily engagement with the process and product. This paper discusses an exercise in a Human Factors/Ergonomics course in interior design where students create ‘A 3D Experience’. Analysis of exemplary work suggests various ways in which different senses may come forth into awareness to sometimes enrich and at other times limit embodied space, thus opening up a venue of inclusivity in novel and unpredictable ways. Research conducted on student perspectives reveals that the assignment had positive impact on their understanding and awareness of, and attitudes towards, inclusive design, as well as creative thinking.

Tactile perception by friction induced vibrations
(2011) Fagiani, R.; Massi, F.; Chatelet, E.; Berthier, Y.; Akay, A.
When a finger moves to scan the surface of an object (haptic sensing), the sliding contact generates vibrations that propagate in the finger skin activating the receptors (mechanoreceptors) located in the skin, allowing the brain to identify objects and perceive information about their properties. The information about the surface of the object is transmitted through vibrations induced by friction between the skin and the object scanned by the fingertip. The mechanoreceptors transduce the stress state into electrical impulses that are conveyed to the brain. A clear understanding of the mechanisms of the tactile sensing is fundamental to numerous applications, like the development of artificial tactile sensors for intelligent prostheses or robotic assistants, and in ergonomics. While the correlation between surface roughness and tactile sensation has already been reported in literature, the vibration spectra induced by the finger-surface scanning and the consequent activation of the mechanoreceptors on the skin have received less attention. In this paper, frequency analysis of signals characterizing surface scanning is carried out to investigate the vibration spectrum measured on the finger and to highlight the changes shown in the vibration spectra as a function of characteristic contact parameters such as scanning speed, roughness and surface texture. An experimental set-up is developed to recover the vibration dynamics by detecting the contact force and the induced vibrations; the bench test has been designed to guarantee reproducibility of measurements at the low amplitude of the vibrations of interest, and to perform measurements without introducing external noise. Two different perception mechanisms, as a function of the roughness wavelength, have been pointed out. The spectrum of vibration obtained by scanning textiles has been investigated. © 2011 Elsevier Ltd. All rights reserved.

Universal product design involving elderly users: a participatory design model
(Elsevier, 2004-07) Demirbilek, O.; Demirkan, H.
Recent studies have shown that people prefer to age in their familiar environments, thus guiding designers to provide a safe and functionally appropriate environment for ageing people, regardless of their physical conditions or limitations. Therefore, a participatory design model is proposed where human beings can improve their quality of life by promoting independence, as well as safety, useability and attractiveness of the residence. Brainstorming, scenario building, unstructured interviews, sketching and videotaping are used as techniques in the participatory design sessions. Quality deployment matrices are employed to find the relationships between the elderly user's requirements and design specifications. A case study was devised to apply and test the conceptual model phase of the proposed model.
