Measuring expectation for an affordance gap on a smartphone user interface and its usage among older adults
2020
The smartphone has become a ubiquitous mobile communication tool that plays a crucial role in the daily lives for Malaysian older adults. However, it is not easy for older adults to learn new interaction modes and adopt the smartphone user interface. In this paper, we aim to examine the affordances of a smartphone user interface and its usage by older adults through the lens of Norman’s execution/evaluation action cycle (EEAC) framework. A mobile-user interaction study was administered with four tasks. A paired sample t-test was conducted to analyze the affordance gap between different levels of expectation. The results revealed that three tasks (making phone calls, adding contacts, and usi…
From Technology to the Human User
2008
When thinking of users, it is possible to look at them from a variety of perspectives. One essential way of considering users within the human–technology environment involves technical concepts. In this manner, we define what users should be able to do with a particular technical system. As such, there are tasks to accomplish and goals to reach by means of some technology, and therefore specific operations must be carried out in order to reach those goals or fulfill those tasks. For example, if someone wishes to buy boots from an eShop, it is necessary to get onto the Internet, find the eShop, find the boots, load them into a virtual shopping cart, and follow the process to check out. Savvy…
Help! Is my Chatbot Falling into the Uncanny Valley? : An Empirical Study of User Experience in Human-Chatbot Interaction
2019
Original article available at http://dx.doi.org/10.17011/ht/urn.201902201607 Advances in artificial intelligence strengthen chatbots’ ability to resemble human conversational agents. For some application areas, it may be tempting not to be transparent regarding a conversational agent’s nature as chatbot or human. However, the uncanny valley theory suggests that such lack in transparency may cause uneasy feelings in the user. In this study, we combined quantitative and qualitative methods to investigate this issue. First, we used a 2 x 2 experimental research design (n = 28) to investigate effects of lack in transparency on the perceived pleasantness of the conversation in addition to percei…

Sosiaalialan asiakastietojärjestelmissä paljon parannettavaa: käyttäjäkokemukset 2019
2020
Sosiaali- ja terveydenhuollon digitalisaatiolle on asetettu paljon odotuksia niin palveluiden laadun, saavutettavuuden kuin tehokkuuden osalta. Asiakas- ja potilastietojärjestelmiltä odotetaan paljon tavoitteiden saavuttamiseksi. Asiakastietojärjestelmät ovat laajasti käytössä sosiaalialalla, mutta niiden käyttöä työvälineenä ja niiden avulla saavutettuja hyötyjä on tutkittu ammattilaisten näkökulmasta vain vähän. Keväällä 2019 kartoitettiin ensimmäistä kertaa valtakunnallisesti sosiaalialan ammattilaisten käyttäjäkokemuksia asiakastietojärjestelmistä. Tässä artikkelissa kuvataan kyselytutkimuksen toteutus ja tulokset eniten käytettyjen tuotemerkkien osalta. Tutkimus toimii pilottina vuonna…
The interplay between media-for-monitoring and media-for-searching: How news media trigger searches and edits in Wikipedia
2016
This study investigates how traditional news media and Internet services have become entangled in recipients’ habits of gathering information on current topics. Push media enable citizens to scan the issue environment while pull media enable them to seek out in-depth information if information needs have been elicited. Furthermore, content quality in many pull media may increase when more users generate content, removing flaws and adding information. We expected that TV and newspaper coverage of an issue will lead to increases in (a) searches for and (b) user edits in related articles in the online encyclopedia Wikipedia. Our findings reliably support the hypotheses, but the extent to whic…
Defining user experience goals to guide the design of industrial systems
2015
The key prerequisite for experience-driven design is to define what experience to design for. User experience (UX) goals concretise the intended experience. Based on our own case studies from industrial environments and a literature study, we propose five different approaches to acquiring insight and inspiration for UX goal setting: Brand, Theory, Empathy, Technology, and Vision. Each approach brings in a different viewpoint, thus supporting the multidisciplinary character of UX. The Brand approach ensures that the UX goals are in line with the company's brand promise. The Theory approach utilises the available scientific knowledge of human behaviour. The Empathy approach focuses on knowing…
‘I’m still the master of the machine.’ Internet users’ awareness of algorithmic decision-making and their perception of its effect on their autonomy
2020
Algorithms are an integral part of our everyday lives and shape the selection and presentation of information and communication on the internet. At the same time, media users are faced with a lack of control and transparency when interacting with these systems because algorithms largely remain black boxes to end users. Relying on the notion that algorithms are socio-technical systems that comprise both technical and human components, this paper examines internet users’ awareness of algorithms in different areas of internet use and inquires into users’ perceptions of the impact of algorithms on their autonomy when interacting online. Empirically, we rely on qualitative interviews with 30 Ger…
Sociodemographic Characteristics and Interests of FeverApp Users
2021
The FeverApp Registry is a model registry focusing on pediatric fever using a mobile app to collect data and present recommendations. The recorded interactions can clarify the relationship between user documentation and user information. This initial evaluation regarding features of participants and usage intensity of educational video, information library, and documentation of fever events covers the runtime of FeverApp for the first 14 months. Of the 1592 users, the educational opening video was viewed by 41.5%, the Info Library was viewed by 37.5%, and fever events were documented by 55.5%. In the current sample, the role of a mother (p <
A topology-constrained distance network algorithm for protein structure determination from NOESY data.
2005
This article formulates the multidi- mensional nuclear Overhauser effect spectroscopy (NOESY) interpretation problem using graph theory and presents a novel, bottom-up, topology-con- strained distance network analysis algorithm for NOESY cross peak interpretation using assigned resonances. AutoStructure is a software suite that implements this topology-constrained distance net- work analysis algorithm and iteratively generates structures using the three-dimensional (3D) protein structure calculation programs XPLOR/CNS or DY- ANA. The minimum input for AutoStructure in- cludes the amino acid sequence, a list of resonance assignments, and lists of 2D, 3D, and/or 4D-NOESY cross peaks. AutoStru…
