Towards reliable and responsible social network research by Tristan Henderson – University of St Andrews

This seminar is suitable for CS3053-RPIC

Abstract
Social network sites (SNSs) such as Facebook and Twitter are used by hundreds of millions of people daily. As such they represent an attractive source of data for research. Many researchers have crawled these SNSs to collect data for projects involving psychology, sociology, health, and of course computer science. But there are many risks to naively crawling an SNS, ranging from data protection and privacy concerns to the reliability of the collected data.

Seminar – Connecting Families over Distance – Dr. Carman Neustaedter

Connecting Families over Distance

Families often have a real need and desire to stay connected with their remote family members and close friends. For example, grandparents want to see their grandchildren grow up, empty-nest parents want to know about the well being of their adult children, and parents want to be involved in their children’s daily routines and happenings while away from them. Video conferencing is one technology that is increasingly being used by families to support this type of need. In this talk, I will give an overview of the research that my students and I have done in this space. This includes studies of the unique ways in which families with children, long-distance couples, and teenagers make use of existing video chat systems to support ‘presence’ and ‘connection’ over distance. I will also show several systems we have designed to support always-on video connections that move beyond ‘talking heads’ to ‘shared experiences’.

Autonomy handover and rich interaction on mobile devices by Simon Rodgers

Abstract: In this talk I will present some of the work being done in the new Inference, Dynamics, and Interaction group, at the University of Glasgow. In particular, we are interested in using probabilistic inference to improve interaction technology on handheld devices (particularly with touch screens).

I will show how we are using sequential Monte-Carlo techniques to infer distributions over user inputs which can be (1) augmented with applications to provide a smooth handover of control between the human and device and (2) used to extract additional information regarding touch interactions and subsequently improve touch accuracy.

A large-scale study of information needs by Karen Church

In recent years, mobile phones have evolved from simple communication devices to sophisticated personal computers enabling anytime, anywhereaccess to a wealth of information. Understanding the types of information needs that occur while mobile and how these needs are addressed is crucial in order to design and develop novel services that are tailored to mobile users.

To date, studies exploring information needs, in particular mobile needs, have been relatively small in terms of scope, scale and duration. The goal of this work is to investigate information needs on a much larger-scale and to explore, through quantitative analysis, how those needs are addressed.To this end, we conducted one of the most comprehensive studies of information needs to date, spanning a 3-month period and involving over 100 users. The study employed an intelligent experience sampling algorithm, an online diary and SMS technology to gather insights into the types of needs that occur from day to day.

Our results not only complement earlier studies but also shed new light on the differences between mobile and non-mobile information needs as well as the impact of demographics like gender have on the types of needs that arise and on the means chosen to satisfy those needs. Finally, we point to a number of design implications for enriching the future experiences of mobile users based on our findings..

Proactive contextual information retrieval by Samuel Kaski

A talk on “Proactive contextual information retrieval” by Samuel Kaski of Aalto University and University of Helsinki, Finland.

Abstract:

In proactive information retrieval the ultimate goal is to seamlessly access relevant multimodal information in a context-sensitive way. Usually explicit queries are not available or are insufficient, and the alternative is to try to infer users’ interests from implicit feedback signals, such as clickstreams or eye tracking. We have studied how to infer relevance of texts and images to the user from the eye movement patterns. The interests, formulated as an implicit query, can then be used in further searches. I will discuss our new machine learning-based results in this field, including data glasses-based augmented reality interface to contextual information, and timeline browsers for life logs.

Biological Data: Analysis, Visualisation and Prediction by Geoff Barton – Professor of Bioinformatics, College of Life Sciences, University of Dundee

Abstract: Modern biological research hinges on technologies that are able to generate very large and complex datasets. For example, recent advances in DNA sequencing technologies have led to global collections in the multi-petabyte range that are doubling every five months. These data require organising in a form that allows interpretation by a very large and diverse user community that are interested in everything from human health and disease, through crop and animal breeding to the understanding of ecosystems. In this talk I will first give an overview of core molecular biology concepts and some of the different types of data that are currently collected, I will then focus on work from my group in visualisation and analysis of sequence alignment data before turning to examples of prediction of properties and features from biological data.

Multimodal mobile interaction – making the most of our users’ capabilities by Stephen Brewster, University of Glasgow

Title: Multimodal mobile interaction – making the most of our users’ capabilities


Mobile user interfaces are commonly based on techniques developed for desktop computers in the 1970s, often including buttons, sliders, windows and progress bars. These can be hard to use on the move which then limits the way we use our devices and the applications on them. This talk will look at the possibility of moving away from these kinds of interactions to ones more suited to mobile devices and their dynamic contexts of use where users need to be able to look where they are going, carry shopping bags and hold on to children. Multimodal (gestural, audio and haptic) interactions provide us new ways to use our devices that can be eyes and hands free, and allow users to interact in a ‘head up’ way. These new interactions will facilitate new services, applications and devices that fit better into our daily lives and allow us to do a whole host of new things


I will discuss some of the work we are doing on input using gestures done with fingers, wrist and head, along with work on output using non-speech audio, 3D sound and tactile displays in applications such as for mobile devices such as text entry, camera phone user interfaces and navigation. I will also discuss some of the issues of social acceptability of these new interfaces; we have to be careful that the new ways we want people to use devices are socially appropriate and don’t make us feel embarrassed or awkward


Biography: Stephen is a Professor of Human-Computer Interaction in the Department of Computing Science at the University of Glasgow, UK. His main research interest is in Multimodal Human-Computer Interaction, sound and haptics and gestures. He has done a lot of research into Earcons, a particular form of non-speech sounds. He completed his degree in Computer Science at the University of Herfordshire in the UK. After a period in industry he did his PhD in the Human-Computer Interaction Group at the University of York in the UK with Dr Alistair Edwards. The title of his thesis is “Providing a structured method for integrating non-speech audio into human-computer interfaces”. That is where he developed his interests in earcons and non-speech sound. After finishing his PhD he worked as a research fellow for the European Union as part of the European Research Consortium for Informatics and Mathematics (ERCIM). From September, 1994 – March, 1995 he worked at VTT Information Technology in Helsinki, Finland. He then worked at SINTEF DELAB in Trondheim, Norway.

Idris: Verified Systems Programming with Dependent Types by Edwin Brady

Systems software, such as an operating system or a network stack, underlies everything we do on a computer, whether that computer is a desktop machine, a server, a mobile phone, or any embedded device. It is therefore vital that such software operates correctly in all situations. In recent years, dependent types have emerged as a promising approach to ensuring program correctness using languages and verification tools such as Agda and Coq. However, these tools operate at a high level of abstraction and so it can be difficult to map these verified programs to efficient low level code, working with bit-level operations and interacting directly with system services.

In this talk I will describe Idris, a dependently typed programming language implemented with systems programming in mind. I will show how it may be used to implement programs which interact safely with the operating system, in particular how to give precise APIs for verifiable systems programming with external C libraries.
