This tutorial examines the relationship between usability and user interface discusses how process follows a design-evaluate-redesign cycle. It also some management issues an organization must face when applying techniques.
Digital library search results are usually shown as a textual list, with 10-20 items per page. Viewing several thousand at once on two-dimensional display continuous variables is promising alternative. Since these displays can overwhelm some users, we created simplified that uses categorical and hierarchical axes, called hieraxes. Users appreciate the meaningful limited number of terms each hieraxis. At grid point show cluster color-coded dots or bar chart. see entire result set then click...
The development of mobile apps during the last decade has had a significant increase in its share software market. While there are specific characteristics that separate it from traditional development, is lack guidance on issues encountered process. With aim defining application framework considers developing apps, we started by carrying out systematic mapping study process for applications, then administered survey and completed qualitative with industry experts. These studies allowed us...
The ageing of the population poses a threat to both public and private health social systems. In last 50 years, life expectancy has increased by an average 20 year 2050, will exceed 90 years age. However, quality in is not guaranteed due conditions such as functional decline frailty, ultimately progressing disability. Thus, detection condition time utmost importance. This paper presents ultrasonic sensor-based gait speed measurement device controlled via mobile interface, which permits...
Cross-platform development frameworks for mobile applications promise important advantages in cost cuttings and easy maintenance, posing as a very good option organizations interested the design of several platforms. Given that platform conventions are especially User eXperience (UX) applications, usage framework where same code defines behavior app different platforms could have negative impact UX. This paper describes study two independent teams designed versions application, one using...
The present paper describes a system for older people to self-administer the 30-s chair stand test (CST) at home without supervision. comprises low-cost sensor count sit-to-stand (SiSt) transitions, and an Android application guide through procedure. Two observational studies were conducted (i) in supervised environment (n = 7; m 83.29 years old, sd 4.19; 5 female), (ii) complete unsupervised one age 64-74 old; 3 female). participants asked perform CST with sensor, while member of research...
We aimed to co-create and evaluate an integrated system follow-up frailty in a community dwelling environment provide multi-modal tailored intervention. Frailty dependency among the older population are major challenge sustainability of healthcare systems. Special attention must be paid needs particularities frail persons as vulnerable group.To ensure solution fits all stakeholders' needs, we performed several participatory design activities with them, such pluralistic usability...
Population aging threatens the sustainability of welfare systems since it is not accompanied by an extended healthy and independent period in last years life. The Comprehensive Geriatric Assessment (CGA) has been shown to be efficient maintaining at end Frailty monitoring typically carried out for average 6 months clinical settings, while more regular could prevent transition disability. We present design process a system frailty home based on adapted CGA rationale behind its User eXperience...
Older adults' usage of information and communication technology (ICT) is challenged or facilitated by perception usefulness, design, gender, social class, other unspoken political elements. However, studies on the use ICT older adults have traditionally focused explicit interactions (e.g., usability). The article then analyzes how symbolic, institutional, material elements enable hinder from using ICT. Our ethnographic methodology includes several techniques with Spanish adults: 15...
Usability is increasingly recognized as a quality attribute that one has to explicitly deal with during development. Nevertheless, usability techniques, when applied, are decoupled from the software development process. The host of techniques offered by HCI (Human-Computer Interaction) field make task selecting most appropriate ones for given project and organization difficult task. Project managers developers aiming integrate practices into their process have face important challenges, not...
The diversity of User Centred Design (UCD) methods and the difficulties for estimating their cost-effectiveness make planning usability activities in systems development a hard task. Usability Planner is tool to support selection UCD be applied particular project or organization, estimate relative cost benefits applying at different stages.
Lower-limb strength is a marker of functional decline in elders. This work studies the feasibility using quasi-periodic nature distance between subjects’ back and chair backrest during 30-s chair–stand test (CST) to carry out unsupervised measurements based on readings from low-cost ultrasound sensor. The device comprises an sensor, Arduino UNO board, Bluetooth module. Sit-to-stand transitions are identified by filtering signal with moving minimum filter comparing output adaptive threshold....
