School Seminar: “The path to Cellular IoT and the promise of 5G” by Frankie Garcia

The School of Computer Science welcomes Frankie Garcia from Keysight Technologies, Edinburgh. Frankie Garcia

Abstract: Over the last two decades we have witnessed an unprecedented growth in the number of Internet-connected devices via the Cloud (storage, compute and intelligent analytics) generally referred to as the Internet of Things (IoT). This includes both machine-to-machine (M2M) and machine-to-person communications on a massive scale. While this growth has been fuelled through standardisation and engineering of short range wireless systems such as Bluetooth, Wi-Fi and Zigbee, cellular technologies promise wide area coverage, ease of deployment and low-cost/low-energy devices capable of operating for many years on a small battery. However, IoT technologies based on existing cellular systems are not optimized to support the huge number of simultaneous connections needed for widespread adoption. To achieve this, radical changes are required in protocol layer design, radio access techniques, and future integrated platforms that can scale and handle millions of devices efficiently. These devices will themselves exhibit a diverse set of requirements with respect to reliability, latency and availability. For these reasons, Cellular IoT has become one of the most important use case drivers in the evolution of future 5G technologies and architectures.

In this talk we will briefly introduce the audience to existing cellular standards and systems to support IoT communications, including their strengths and limitations. We will then cover the path towards more efficient cellular technologies being developed today under 3GPP, focusing heavily on Narrowband IoT (NB-IoT). This will be followed by a short introduction to 5G mobile network evolution needed to reduce signalling overheads and cater for a diversity of IoT use cases. This evolution is driven by tried and tested technologies used for virtualisation such as Software Defined Networking (SDN) and Network Function Virtualisation (NFV). “Slicing”, is a much discussed design principle that that includes logical access, compute, storage and networking for on demand architectures tailored to individual service requirements. Finally, we will present the development of an agile SDR platform targeting experimentation and prototyping of NBIoT systems.

Elise van den Hoven : Materialising Memories: a design research programme to study everyday remembering

Abstract


Perhaps the term computer ‘memory’ has led people to believe that human memory has to be perfect and infallible. Many people worry when they realise they forget and some turn to recording and collecting as much as they can, e.g. photos or videos through life logging. Some people assume that by collecting they can avoid forgetting or at least have access to the information anytime later. And that is where they might be wrong. First of all, recordings are not equivalent to memories, and memories ‘can not be stored’. Secondly it has already been shown that people collect too much and organize too little for them to be able to find information later [1]. Thirdly, human memory works best when we forget… a lot.

What I want to talk about is my vision [2] that we can use design research to support human remembering by supporting our memory’s functions [3], which include a directive function (using the past to guide present and future thoughts and behaviours, e.g. solving problems), a self-representative function (creating a sense of self over time) and a social function (developing and nurturing relationships, through sharing of personal experiences). It is important to realise that in order to support these functions there is no need to improve our remembering capabilities, however it could benefit from the right type of support. Since remembering is a reconstructive process, individual memories are subject to change, continuously, and what someone experiences as a memory does not have to be the same as what happened or what other people remember from the experience.

Bits of information from the original experience can be used to stimulate and facilitate the reconstruction process. These so-called memory cues [4], which can be anything: from a photo, a song to a person or a location, are at the core of our research. We use a people-centred approach to study memory cues in everyday life, which informs the design of interactive systems that present these memory cues. Since these cues are often digital, while people prefer material objects [e.g. 5], we combine material and digital in our studies and designs.

Daniel Archambault : Effective Visualisation of Static and Dynamic Graphs

Abstract

Visualising dynamic graphs is important for many application areas.  For social media networks, they can help us understand the interaction and interests of users online.  In biology, they can illustrate the interactions between genes and biological processes.  Understanding and designing effective visualisation methods for dynamic network data is fundamental to these areas as well as many others.  In this talk, we focus on the effective presentation of dynamic networks.  In particular, we summarise recent results on dynamic graph visualisation with respect to animation (presentation of interactive movies of the data), small multiples (presenting the data through several linked windows like a comic book), and drawing stability (the visual stability of the data presentation).  We conclude with some recent work on scalable graph visualisation and in the visualisation of sets and their intersections.

Biography

Daniel Archambault has been working in the field of information visualization for ten years. His work in this area has focused on the development and evaluation of techniques for visualizing dynamic networks and scalable graph visualizations.  His research has been been applied to many areas outside of computer science, including the digital humanities, biology, networking, sociology, and social media analysis.

Keith Cheverst: Investigating the Shared Curation of Locative Media relating to the Local History of a Rural Community

Abstract

In this talk I will present experiences and insights from our studies involving locative media, local history and community. Our work in the village of Wray has involved the longitudinal and ‘in the wild’ deployment of ‘digital noticeboard’ displays (conceived as technology probes) that support the sharing of photos/images. A significant portion of the submitted photo content relates to Wray’s local history and features of Wray’s landscape. Residents of the village have helped shape the system through involvement in co-design workshops. A key motivation of our current studies (as part of the SHARC project) is to explore issues around the co-curation of locative media experiences. A field trial (involving both residents and visitors) and a design workshop revealed both opportunities and challenges for the co-curation approach.

School Seminar ‘Closure Experiences in Digital Product Design’ by Joe Macleod

“Closure Experiences in Digital Product Design. The loss of the resolution in the shop of abundance”

F8_2bLVV

Abstract
Most experiences in life are punctuated by a closure experience. In the past these were profound; however, over generations we have distanced ourselves from meaningful closure experiences thanks to our lifestyles increasing in comfort, the church weakening and medicine advancing. This has seemingly freed us from the shackles of the ultimate closure experience – death – and sanctioning our personal pursuit of heaven on earth in the form of consumption. We are now encouraged to drunkenly stumble from purchase to purchase, with any sense of longevity and responsibility removed. Long term side effects of this are exampled in the Product, Service and Digital landscapes that we frequent. The consequences of our behaviour results in a changing climate, industries fined billions for mis-selling and individuals casually eroding their personal online reputations. Many of us are active in the creation of services, products or digital products; making them attractive, engaging and usable for consumers, but we often overlook concluding these experiences for the user in a responsible way. Closure Experiences offers a model to frame this change.

Bio

School Seminar ‘Paraphrase Generation from Latent-Variable PCFGs for Semantic Parsing’ by Shashi Narayan

Abstract:

One of the limitations of semantic parsing approaches to open-domain question answering is the lexicosyntactic gap between natural language questions and knowledge base entries — there are many ways to ask a question, all with the same answer. In this paper we propose to bridge this gap by generating paraphrases to the input question with the goal that at least one of them will be correctly mapped to a correct knowledge-base query. We introduce a novel grammar model for paraphrase generation that does not require any sentence-aligned paraphrase corpus. Our key idea is to leverage the flexibility and scalability of latent-variable probabilistic context-free grammars to sample paraphrases. We do an extrinsic evaluation of our paraphrases by plugging them into a semantic parser for Freebase. Our evaluation experiments on WebQuestions benchmark dataset show that the performance of the semantic parser significantly improves over strong
baselines.

School Seminar: ‘Probabilistic Formal Analysis of App Usage to Inform Redesign’ by Oana Andrei

The School of Computer Science are delighted to welcome Dr Oana Andrei, from the University of Glasgow, to give her talk on Probabilistic Formal Analysis of App Usage to Inform Redesign.

Oana-portrait-180width

Abstract: Good design of mobile apps is challenging because users are seldom homogeneous or predictable in the ways they navigate around and use the functionality presented to them. Recently we set out a process of app analysis intended to support understanding of use but also redesign using probabilistic model checking. In this talk I will show how to infer admixture models of activity patterns from various time cuts of app usage logs, characterise the activity patterns by probabilistic temporal logic properties using model checking, and compare the admixture models longitudinally and structurally. I will illustrate this work via a case study of a mobile app presenting analytic findings and discussing how they are feeding into redesign. We had posited that two activity patterns indicated two separable sets of users, each of which might benefit from a differently tailored app version, but our subsequent analysis detailed users’ interleaving of activity patterns over time – evidence speaking more in favour of redesign that supports each pattern in an integrated way. We uncover patterns consisting of brief glances at particular data and recommend them as possible candidates for new design work on widget extensions: small displays available while users use other apps.

Bio: Oana Andrei is a Research Fellow at the School of Computing Science, University of Glasgow. Her research interests involve fundamental aspects of theoretical computer science, mainly formal modelling and analysis of concurrent and stochastic systems. The applications I study concern mobile app analytics, vehicular networks, sensor systems, biochemical networks, and autonomic computing.

Seminar: “Data Exploration on Smart watches” by Dr Rachel Menzies

rachel menzies

Abstract:

For many of us, interacting with data on mobile devices such as phones and tablets is commonplace in our lives, e.g. phone call data, TV guide, maps, fitness and wearable data. With the introduction of smart watches, the screen size of mobile devices has dramatically decreased. This reduction in screen real estate provides challenges for the design of interfaces, including the presentation and exploration of data visualisations. Using bar charts as an example, this presentation will explore the shortcomings of current zooming techniques on very small screens and consider proposed guidelines for the development of simple data exploration applications. Key design features such as the need for overview and context will be considered in respect to a simple and effective data exploration task.

Seminar: “Interaction, Embodiment and Technologies in Early Learning” by Dr Andrew Manches

as

Abstract: 

 

Most of us might agree that ‘hands-on learning’ is good for children in the early years. But why? Is it simply more fun and sociable, or are there any more direct cognitive benefits? And what determines definitions of ‘hands-on’? Can we include iPads? This talk will draw upon an ESRC-funded project to examine the educational implications of recent theoretical arguments about the embodied nature of cognition. Video data from the project will be used to illustrate the methodological significance of the way children gesture when describing mathematical concepts and evaluate a hypothesis that numerical development is grounded upon two particular embodied metaphors. If correct, this presents a serious challenge to traditional approaches to the types of learning materials we offer children. The talk then demonstrates two embodied technologies to consider the potential of new forms of digital interaction to further our understanding of embodied cognition as well as support early learning.
