MOBILEHCI

The main aim of this PhD study is to develop new methods for conducting field experiments to evaluate mobile systems and services. A framework is proposed for automatic and remote capture and analysis of usage and contextual data on the mobile devices. ...

This research examines the use of formal computational models to design intelligent device interfaces able to predict the function or application a user will use and automatically invoke this function. Computational models considered are Markov Chains, ...

There has been a rapid growth in navigation aids recently. However, no meaningful personalization exists in these devices. Theories and pilot studies show the importance of individual differences in designing pedestrian navigation assistants. I take a ...

Mobile phones may interrupt in any place at any time. Using the SocioXensor research tool on people's own mobile phones, we conducted an experience sampling study to explore which context information predicts a person's availability for a phone call, ...

In this paper, we investigate possibilities and limitations of temperature change as a method for information display in mobile applications. While some widespread and well-recognized haptic displays such as force-feedback often trigger the user's ...

We developed a novel wearable tactile display system as an alternative to the visual and audio displays routinely used by anesthesiologists to monitor patients in the operating room (OR). Visual displays and auditory alarms can be distracting or ...

This paper presents a photo browsing system on mobile devices to browse and search photos efficiently by tilting action. It employs tilt dynamics and a multi-scale photo screen layout for enhancing the browsing and the search capability respectively. ...

In this paper we present Community2Go, a community portal for mobile devices with small displays. Community2Go offers relevant functions for social interaction and access to Communities of Interest (CoIs) set up by the FIT community toolbar. Thus, ...

In this paper, we describe the development and experiences with a mobile group communication application, mCell, that runs on a mobile phone. We present the underlying design implications, the application implementation, and a user study, where three ...

Conversation partners on mobile phones can align their walking gait without physical proximity or visual feedback. We investigate gait synchronization, measured by accelerometers while users converse via mobile phones. Hilbert transforms are used to ...

This paper will describe a novel interaction technique that allows mobile phone users to create and share contextualised media packages between their personal, BlueTooth enabled camera phones, and situated public displays. Unlike other solutions to this ...

This paper reports on an exploratory study of a mobile communication prototype mGuide that enables continuous and data rich messaging across the mobile and desktop platform, augmented by complementary Web services. The study focuses on design aspects of ...

Mobile devices equipped with near-field communication can be used in a variety of settings to interact with the real world. In this study, we assessed user experiences with such mobile devicesfor different groups of users to better understand the ...

Companies deploy mobile business services to enable efficient work processes and gain increases in productivity. However, the success of the services in fulfilling these goals depends on several factors from the usability of the service to its success ...

In this paper, we introduce a method for design evaluation of mobile devices using virtual reality based prototypes. For this, we present technologies for a classification of design parameters and for visualizing mobile devices with high quality 3D ...

In this paper, we report, first of all, the discovery of a particular kind of emerging social practice involving the exchange of multimedia content on mobiles that we label 'trafficking'. Second, the iteration of a design solution to extend these ...

In this paper we examine the role of social context --- for example social relationships or mood --- in the use of mobile phones. A mobile system that uses information on social context can provide a less obtrusive and a more natural way of interaction: ...

Mobile phone users have to deal with limited battery lifetime through a reciprocal process we call human-battery interaction (HBI). We conducted three user studies in order to understand HBI and discover the problems in existing mobile phone designs. ...

A field study has been conducted to investigate the naturalistic use of cell phone applications in driving, home, work, and school and during daytime and nighttime. GPS coordinates are used to determine whether cell phone users are driving. The ...

The paper reports a mobile application that allows users to share photos with other co-present users by synchronizing the display on multiple mobile devices. Various floor control policies (software locks that determine when someone can control the ...

We discuss the design of speech-based interaction systems from the perspective of affordance. It is our claim that many of the problems associated with speech interaction stems from a lack of a deeper understanding of the communicative nature of speech ...

This paper reports the results of a field experiment where a Near Field Communication (NFC) enabled mobile phone was used as a user interface element so as to enable home-dwelling elderly people to choose their meals to be delivered by means of a home ...

The key for successfully deploy mobile applications is the ability to understand the specific needs of its customers. In the field of mobile health monitoring, the currently most important user group is the group of persons of the age 50+. In our ...

Episodic memory exercises such as reminiscing and storytelling have been shown to provide therapeutic benefits for older adults by prolonging their ability to lead an independent lifestyle. In this paper, we describe a mobile reminiscence tool called ...

The Mobile Sales Assistant helps retailers and customers to check the availability of articles with any NFC enabled mobile phone at the Point of Sale. The application uses NFC tags attached to products or to warehouse shelves to identify the articles by ...

The proposed demonstration is based on the work performed in the PERCI project and presents a generic framework to access and interact with Web Services through mobile interaction with real world objects. The demonstration will put a focus on the front-...

An indicator with switchable faces that suits the cellular phone keypad is proposed and implemented. The prototype, which can show 3 patterns, consists of notch filters (each of which yields a different pattern) and light sources. Each pattern, which ...

OpenVG 1.0 is a 2D vector graphics standard and its API (Application Programming Interface) was released by the Khronos Group. In this paper, we introduce our OpenVG 1.0 implementation, accelerated by OpenGL ES 1.x hardware. Our implementation is an ...

"Connected anytime, anywhere, anyhow" is what the Dutch research programme Freeband envisions. However, how does always being connected, anywhere and anytime affect your life? Lifelink, an interactive simulation, enables users to experience the impact ...

Short message service (SMS) is extremely popular today. Currently it is being mainly used for peer-to-peer communication. BlogWall extends the SMS to a new level of self-expression and public communication by combining art and poetry. The application ...
