Feedback and response time GOAL-DRIVEN DESIGN . Good interaction design is driven by a human connection . Tactics for designing for your target user: . Personas: Personas are fictional characters created from the behaviors and psychologies of your target users. Personas come in handy as a reference when making crucial design decisions, for example, “What kind of checkout process would Sally the Seasonal Shopper prefer?” . User Scenarios: Related to personas, user scenarios explain how the personas act when using the site. For example, “It’s Black Friday, and Sally the Seasonal Shopper has a long list of presents to buy online before work.” User stories urge you to think critically about your personas’ behaviors so you design the UI to suit them. USABILITY . “Usability is a quality attribute that assesses how easy user interfaces are to use.” (Jakob Nielsen) . The word "usability" also refers to methods for improving ease-of-use during the design process. Usability is defined by 5 quality components: 1. Learnability: How easy is it for users to accomplish basic tasks the first time they encounter the design? 2. Efficiency: Once users have

Smith2,3 1The Information School 2Intel Research Seattle 3Transmutable Networks LLC DUB Group 1100 NE 45th Street, 6th Floor 4742 42nd Ave. SW #326 University of Washington Seattle, WA 98105 USA Seattle, WA 98126 USA Seattle, WA 98195 USA [email protected] {skane, wobbrock}@u.washington.edu ABSTRACT Using a mobile device while moving limits attention and motor ability and can result in reduced performance. Mobile devices that can sense and adapt to contextual factors such as movement may reduce this performance deficit. We performed two studies evaluating the feasibility of walking user interfaces (WUIs) that adapt their layout when the user is moving. In a pilot study with 6 users, we evaluated the effects of different button sizes on performance when walking while using a portable music player. Results showed significant interactions between size and movement. In the second study, 29 users evaluated the performance of a WUI that dynamically changed button sizes as the user moved. Results show that our dynamic user interface performs at the level of its component static interfaces without any additional penalty due to adaptation. This work adds to our design knowledge about walking user interfaces and provides lessons learned in evaluating mobile devices while walking in Figure 1.

  • Mobile Interaction Design: Techniques for Early Stage In-Situ Design
    10 Mobile Interaction Design: Techniques for Early Stage In-Situ Design Marco de Sá, Luís Carriço & Carlos Duarte LaSIGE and Faculty of Sciences, University of Lisbon Portugal 1. Introduction The recent globalization of mobile technology and its overwhelming presence on everyday life through various societal groups and activities has raised its importance to unprecedented levels. Mobile devices’ diverse shapes, small size and distinctive characteristics impel their use in diverse and ubiquitous scenarios, cementing their presence within our work, social and entertainment activities. Accordingly, as they assume a greater meaning and a wider role of functionalities, a corresponding amount of new usage paradigms is also emerging. Consequentially, designers are increasingly faced with new design challenges, needing to cope with added difficulties of creating solutions for multiple contexts, users, purposes and new ubiquitous usage behaviours. Simultaneously, they need to cope with and leverage the small size factor and the peculiar or mixed interaction modalities (e.g., touch screen in concert with keyboard or voice) that define the trends of emerging mobile devices. Contrastingly, design problems for mobile devices, and corresponding solutions, have only recently begun to be partially and superficially addressed. Difficulties and challenges are spread through various stages of design. Three phases are particularly interesting: (1) requirements and data gathering on mobile contexts; (2) prototyping for small devices and (3) evaluation on real-world settings. Currently used approaches and existing methodologies still lack specific techniques to support design on such demanding conditions, hindering the design process and resulting in poor software regarding usability. Even recent approaches generally rely on simulations, lab experiences or derive directly from non-mobile techniques, colliding with studies that have clearly demonstrated the need to take the design process out of the lab when it comes to mobile devices.

Linz, May 2018 Dipl.-Ing. Elmar Krainz, bakk. techn. Abstract The market for apps and mobile software is on the rise and this goes hand in hand with the number of apps in the stores, which has recently hit 3 million available apps (see https://www:statista:com/statistics/266210/). Due to this development, the natural user interaction of smartphones plays a crucial role. People with disabilities benefit from the increasing digital technology in general, but only if it is accessible. However, apps are often not accessible for people with disabilities since touch screens and visual representation very often overlook their needs. According to the UN Convention on the Rights of Persons with Disabilities around 650 million people of the world’s population are handicapped.

  • Distinctive Aspects of Mobile Interaction and Their Implications for the Design of Multimodal Interfaces
    Distinctive Aspects of Mobile Interaction and their Implications for the Design of Multimodal Interfaces Luca Chittaro HCI Lab Dept. of Math and Computer Science University of Udine via delle Scienze, 206 33100 Udine, Italy http://hcilab.uniud.it ABSTRACT. People want to do more with their mobile phones, but their desire is frustrated by two classes of limitations. One is related to the device, its hardware and software. The other is related to the context, and comprises perceptual, motor, cognitive and social aspects. This paper will discuss some of the opportunities and challenges that this complex scenario presents to multimodality, which can be a key factor for a better design of mobile interfaces to help people do more on their mobile phones, requiring less time and attention. Keywords: mobile devices, multimodal interfaces, attention, cognitive workload mitigation, human factors, human-computer interaction. Introduction People want to do more with their mobile devices, but their desire is frustrated by different kinds of limitations. A pioneering work on studying the peculiar aspects of interaction in mobile conditions was carried out by Pascoe et al. [22]. They focused on a specific class of users (fieldworkers, in particular archaeologists and ethologists) and on a specific task (fieldwork data collection) pointing out that mobile devices could effectively support it, provided that the following requirements are taken into account: (i) allow to collect data whenever and wherever the fieldworker wants, whether she is standing, crawling or walking, (ii) minimize the amount of user attention required to interact with the device, (iii) enter high volumes of data quickly and accurately, (iv) have the device sense the environment to record some context information such as location, and help in Preprint Version analyzing it (e.g., plotting her observations to a map, based on the locations in which they have been recorded).

  • Designing an Interface for a Mobile Application Based on Children's Opinion
    Paper—Designing an Interface For a Mobile Application Based on Children’s Opinion Designing an Interface For a Mobile Application Based on Children’s Opinion https://doi.org/10.3991/ijim.v11i1.6099 Radoslava Kraleva South-West University “Neofit Rilski”, Blagoevgrad, Bulgaria [email protected] Abstract—Modern mobile devices are becoming more and more popular in children’s lives. Therefore, the development of appropriate applications for them is of crucial importance. This article focuses precisely on the design of in- terfaces for mobile application with the participation of children. An overview of contemporary research related to Child-Computer Interaction (CCI) is made. The opinion of the children aged from 4 to 13 years on the possibilities and the features of the interface of mobile applications is investigated. The results ob- tained are summarized and analyzed. The prototype of a mobile application which corresponds to the preferences of the children under investigation is pre- sented. Finally, the article specifies some future directions for research. Index Terms—Children, mobile application for children, software engineering, child-computer interaction (CCI), mobile learning. 1 Introduction Mobile technologies are closely related to the modern way of life. Young children who cannot read or write until the age of 7 in some cases, already know how to use a tablet and/or a smartphone. This is possible due to the interactive and easy to use (friendly) software products. However, it must be borne in mind that the applications suitable for children should be different from those for adults. Usually, they are funny, intuitive and interesting, hence, they keep children’s attention for a long period of time.

  • A Software Library for Multiplatform Tangible Mobile Interaction 1 INTRODUCTION
    ToMMI A Software Library for Multiplatform Tangible Mobile Interaction Francesco Strada and Andrea Bottino Department of Control and Computer Engeneering, Politecnico di Torino, Torino, Italy Keywords: Tangible Interaction, Capacitive Displays, Passive Tokens, Multiplatform Mobile Computing. Abstract: In this paper we present ToMMI (TOkens for Multiplatform tangible Mobile Interaction), a software library capable of supporting both tangible and multi-touch interaction on mobile devices. ToMMI exploits 3D printed tokens that can be recognized and tracked on devices equipped with commercial capacitive displays. Results shows that the computational core of ToMMI is lightweight and can extract token information in less than a millisecond. Furthermore, the library has an intuitive interface, which facilitates its use, and it is based on a portable framework that guarantees the deployment of any application based on it on a plethora of dif- ferent smartphones and tablets. We also report that ToMMI code is available, open source, for the research community. 1 INTRODUCTION of tools supporting the development in the mobile area.
