Apperceiving visual elements in human-technology interaction design
2017
Visual design of technological artefacts is an integral part of peoples’ experiences in technology-interaction. Visual product properties are capable of eliciting affective responses and multisensorial experiences in human- technology interaction. Current research in the field of human-technology interaction focuses on visual, emotional and multisensory aspects of interaction in addition to functionality and usability. However, the focus has not been on how performative aspects of visual elements affect technology-interaction as a cognitive sense making process shaping human experiences. To design technological contact points to be made sense of, the substance of visual representations requ…
Visual search in graphical interfaces : a user psychological approach
2003
Marketta Niemelä yhdistää väitöskirjassaan käyttäjän psykologian tutkimusta ihmisen ja tietokoneen välisen vuorovaikutuksen tutkimukseen. Ei riitä, että tunnetusta psykologiasta irrotetaan soveltuvaa detaljitietoa käyttöliittymien suunnittelun tueksi, vaan käyttäjää on pystyttävä ymmärtämään syvällisemmin, jotta pystytään suunnittelemaan helppokäyttöisiä tietokoneita. Ihmistä on tutkittava silloin, kun hän toimii tietokoneen kanssa.Marketta Niemelä painottaa käyttäjäpsykologista näkökulmaa käyttöliittymien tutkimuksessa. Erityisesti ihmisen psykologisen tiedonkäsittelyn periaatteiden tunteminen on tärkeää. Tiedonkäsittelypsykologia eli kognitiivinen psykologia tutkii muun muassa ihmisen hav…
Life-based design for technical solutions in social and voluntary work
2012
The Social and Voluntary work sector operates outside the organised boundaries and systems of normal business, financial and government organisational institutions. My target during this research has been to develop an optimum solution for decision support towards committing and accepting resources in the Social Work and Voluntary sector. In initial part of this monograph, I have traced the history of Design Thinking from the time it was ‘art and craft’ until modern times where multiple approaches are tried, tested and implemented for solution development. For the actual application development, I have chosen the Life-based Design conceptual framework. Three design iterations were made in t…
Analysis of Somatosensory Cortical Responses to Different Electrotactile Stimulations as a Method Towards an Objective Definition of Artificial Senso…
2022
Sensory feedback is a critical component in many human-machine interfaces (e.g., bionic limbs) to provide missing sensations. Specifically, electrotactile stimulation is a popular feedback modality able to evoke configurable sensations by modulating pulse amplitude, duration, and frequency of the applied stimuli. However, these sensations coded by electrotactile parameters are thus far predominantly determined by subjective user reports, which leads to heterogeneous and unstable feedback delivery. Thus, a more objective understanding of the impact that different stimulation parameters induce in the brain, is needed. Analysis of cortical responses to electrotactile afference might be an effe…
Virtual violin in the digital domain : physical modeling and model-based sound synthesis of violin and its interactive application in virtual environ…
2004
Viulun mallintaminen on tunnustettu maailmanlaajuisesti erittäin haasteelliseksi ongelmaksi. Väitöskirjan syntymistä ja tutkimuksessa esitettyjen uusien tekniikoiden kehittämistä ovatkin ohjanneet pitkälle käytännön syyt. On ollut tarve pyrkiä luomaan aiempaa luotettavampia ja todenmukaisempia fysikaalisia malleja, mm. äänisynteesiä varten syntetisaattoreihin ja esimerkiksi mobiililaitteisiin, Jan-Markus Holm kertoo viulun fysikaalista mallintamista käsittelevän väitöstyönsä taustoista. This thesis discusses techniques for physical modeling and model-based sound synthesis of violin, and human-computer interaction in virtual domain. The violin model is considered by means of controlling a vi…
Grounding the innovation of future technologies
2005
Mobile and ubiquitous technologies can potentially change the role of information and communication technology in human lives. Empirical, human-centered approaches are emerging as an alternative to technology-driven approaches in the innovation of these technologies. Three necessary empirical stages, intertwined with analytical ones and with each informing and grounding the succeeding stages, are analyzed. First, needfinding is utilized to discover societal and individual demands for technology. Second, observational and experimental studies examine the social and cognitive preconditions for interaction. From these two steps, a hypothesis is formulated regarding how technology will change e…

Simplicity and the art of something more: A cognitive-semiotic approach to simplicity and complexity in human-technology interaction and design exper…
2018
In human–technology interaction, the balance between simplicity and complexity has been much discussed. Emphasis is placed on the value of simplicity when designing for usability. Often simplicity is interpreted as reductionism, which compromises both the affective nature of the design and usability itself. This paper takes a cognitive–semiotic approach toward understanding the dynamics between the utilitarian benefits of simplicity in design and the art of something more: considerate complexity. The cognitive–semiotic approach to human–technology design experience is a vehicle for explaining the relationship between simplicity and complexity, and this relationship’s multisensory character …
Emotions and Technoethics
2020
The relationship between emotions and ethics has been debated for centuries. The act of understanding emotions through the framework of ethics involves accepting that emotions are to some extent culturally dependent. By linking emotions in design to larger ethical discussions, it may be accepted that ethics and design are both technological constructions designed to shape a collective worldview. While both are cultural constructions, they are in constant dialogue with one another through social discourse and individualistic cognitive–affective appraisal processes. This chapter presents an account of technoethics that challenges ideas of ethical values embedded within technology, drawing att…
