Dialing for Displays: Session Initiation Protocol for Opportunistic Augmentation
- 2006. - 1
-
Konferensbidrag (refereegranskat)abstract
- Opportunistic augmentation denotes connecting a personal mobile device to another device to gain a transient advantage for the user. For example, a mobile phone user might borrow a large display and keyboard from a desktop personal computer. This uniquely ubiquitous computing activity requires effective device and service discovery as well as appropriate media usable across two or more devices. In this paper we show how Session Initiation Protocol (SIP), the call signaling protocol for Voice over IP, effectively separates discovery from media-rendering selection in opportunistic augmentation. This separation improves system flexibility while allowing users or system administrators to choose the most appropriate discovery technologies for the environment. We also describe two phone-centric discovery mechanisms and demonstrate the practicality of the system by implementation and use in a test environment.

Usability in Mobile IT systems
- 2005
-
Rapport (populärvet., debatt m.m.)abstract
- In this report we give an overview of usability aspects applicable to mobile devices and systems. A number of research projects from three different application areas are presented and experiences from the projects are discussed.To successfully design usable products, services and systems both for leisure and for mobile work practice has turned out to be a difficult undertaking. Many systems fail because of a number of reasons. Some systems do not fail, but remains difficult and cumbersome to use.A certain immaturity can be observed since developers and designers do not fully utilise the benefits and assets provided by today’s technology in design of mobile systems. For mobile systems, the varying contexts of use become more important. When only relying on existing knowledge of design for stationary systems, important possibilities are often lost and the system has gone astray.

Design and Implementation of Multi-Device Services
- 2007
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- We present a method for developing multi-device services which allows for the creation of services that are adapted to a wide range of devices. Users have a wide selection of electronic services at their disposal such as shopping, banking, gaming, and messaging. They interact with these services using the computing devices they prefer or have access to, which can vary between situations. In some cases, the services that they want to use func-tions with the device they have access to, and sometimes it does not. Thus, in order for users to experience their full benefits, electronic services will need to become more flexible. They will need to be multi-device services, i.e. be accessible from different devices. We show that multi-device services are often used in different ways on different devices due to variations in device capabilities, purpose of use, context of use, and usability. This suggests that multi-device services not only need to be accessible from more than one device, they also need to be able to present functionality and user interfaces that suit various devices and situations of use. The key problem addressed in this work is that there are too many device-service combinations for developing a service version for each device. In-stead, there is a need for new methods for developing multi-device services which allows the creation of services that are adapted to various devices and situations. The challenge of designing and implementing multi-device services has been addressed in two ways in the present work: through the study of real-life use of multi-device services and through the creation of a development method for multi-device services. Studying use of multi-device services has gener-ated knowledge about how to design such services which give users the best worth. The work with development methods has resulted in a design model building on the separation of form and content, thus making it possible to create different presentations to the same content. In concrete terms, the work has resulted in design guidelines for multi-device services and a system prototype based on the principles of separation between form and content, and presentation control.

Gathering design requirements for a microcommunity - the case of preschool parents and teachers
- 2009. - 1
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- A microcommunity for preschool is a community for parents, teachers and other people involved in a preschool child group. The community is a tool for distributing and exchanging information and complements the traditional face to face communication and paper notes in that it makes information available from other places than the home and the preschool facilities. We present a first design iteration for preschool microcommunities with parents and teachers. Teachers have worked with a prototype tool to create microcommunities that has been made available to parents. We present a set of design principles for preschool microcommunities and a new design of the tool.

Generating speech user interfaces from interaction acts
- 2005. - 1
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- We have applied interaction acts, an abstract user-service interaction specification, to speech user interfaces to investigate how well it lends itself to a new type of user interface. We used interaction acts to generate VoiceXML-based speech user interface, and identified two main issues connected to the differences between graphical user interfaces and speech user interfaces. The first issue concerns the structure of the user interface. Generating speech user interfaces and GUIs from the same underlying structure easily results in a too hierarchical and difficult to use speech user interface. The second issue is user input. Interpreting spoken user input is fundamentally different from user input in GUIs. We have shown that it is possible to generate speech user interfaces based on. A small user study supports the results.

Konferensbidrag (refereegranskat)abstract
- We conducted a diary study of how 19 experienced users access Internet from cell phones. Our findings show that participants often chose the cell phone to access the Internet even though they had access to a computer, and the most common location for Internet access from the phone was the home. Reasons for choosing the phone over the computer were speed, convenience and a desire to use the phone. The phone is kept close and is always on which makes it convenient to use. The traditional motivation for mobile services ”finding out something about where you are” only accounts for 15% of the material.

Presence as a foundation for information exchange between parents and pre-school teachers
- 2008. - 1
-
Konferensbidrag (refereegranskat)abstract
- Information technology has not yet fully penetrated the work with pre-school children. We have interviewed parents and pre-school teachers to investigate how they exchange information. Findings show that the information flow relies heavily on presence. The information is concentrated to physical places in the pre-school and in the home which means that information problems arise when children are absent from pre-school or the family is absent from home.

Presence, routines, and technology discrepancy – information exchange between parents and preschool teachers
- 2009. - 1
-
Konferensbidrag (refereegranskat)abstract
- We have interviewed four parents and a teacher at a Swedish preschool to investigate the practices for spreading information in preschool. Our findings suggest that frequent presence in the premises of the preschool is important to get information, and that parents rely heavily on routines to make it work. When either of these points fail, breakdowns occur. Discrepancies in parents’ and teachers’ IT use also complicates the information exchange.

Real-Life Use of Multi-Device Services
- 2006. - 1
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- We have conducted interviews with 22 users of three multi-device services, email and two web communities, to explore practices, benefits, and problems with using services both from desktop computers and mobile devices. Participants reported different usage patterns on different devices, offering support for adapting services to the capabilities of devices. The most common usage problems reported concerned text input and navigation on mobile devices, and data organization over multiple devices.

The Ubiquitous Interactor — Device Independent Access to Mobile Services
- 2005. - 6
-
Ingår i: Computer-Aided Design of User Interfaces IV. - : Springer. ; , s. 271-282
-
Bokkapitel (refereegranskat)abstract
- The Ubiquitous Interactor (UBI) addresses the problems of design and development arising around services that need to be accessed from many different devices. In UBI, the same service can present different user interfaces on different devices by separating user-service interaction from presentation. The interaction is kept the same for all devices, and different presentation information is provided for different devices. This way, tailored user interfaces for many different devices can be created without multiplying development and maintenance work. In this paper we describe the system design of UBI, the system implementation, and two services implemented for the system: a calendar service and a stockbroker service.

Towards Design Guidelines for Multi-Device Services
- 2006. - 1
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Multi-device services need to be adapted to various devices to accommodate users. When deciding how to adapt a multi-device service, several parameters such as device capabilities, usage context, purpose of use, and usability need to be considered. Here, these parameters are discussed and based on the discussion basic design guidelines for multi-device services are presented.

Where would you bring your laptop? – Live blogging in an outdoors mechanical shop
- 2008. - 1
-
Konferensbidrag (refereegranskat)abstract
- We describe the blogging habits of 19 teams of students participating in the KTH triennial carnival. They were blogging in a rough environment, i.e. outdoors while nailing or welding carnival carriages together and painting them, and they were interviewed on site. Astonishingly enough, students did not mind bringing laptops into this environment. 53% of the postings made during the study were made from the construction site. The ability to blog from the site seemed to be important, teams that blogged from the site blogged more that teams who did not.
