Mark Shovman, Measuring the Effectiveness of Abstract Data Visualisations


<!–Speaker: Mark Shovman, University of Abertay, Dundee
Date/Time: 2-3pm September 13th, 2011
Location: 1.33a Jack Cole, University of St Andrews (directions)–>
Abstract:
In natural and social sciences, novel insights are often derived from visual analysis of data. But what principles underpin the extraction of meaningful content from these visualisations? Abstract data visualisation can be traced at least as far back as 1801; but with the increase in the quantity and complexity of data that require analysis, standard tools and techniques are no longer adequate for the task. The ubiquity of computing power enables novel visualisations that are rich, multimodal and interactive; but what is the most effective way to exploit this power to support analysis of large, complex data sets? Often, the lack of fundamental theory is pointed out as a central ‘missing link’ in the development and assessment of efficient novel visualisation tools and techniques.
In this talk, I will present some first steps towards the theory of visualisation comprehension, drawing heavily on existing research in natural scene perception and reading comprehension. The central inspiration is the Reverse Hierarchy Theory of perceptual organisation, which is a recent (2002) development of the near-centennial Laws of Gestalt. The proposed theory comes complete with a testing methodology (the ‘pop-out’ effect testing) that is based on our understanding of the cognitive processes involved in visualisation comprehension.

Title: Empirical Investigation of The Memorability of Gesture Sets
Abstract:
As technology is becoming increasing advanced and sophisticated, various input technologies and new experimental input technologies allow for large numbers of gestures types and new ways in controlling software. However very little is
known about the eects they have and how people learn and remember the various gestures. This presentation will briefly talk about what gestures are, the related work, our experimental study and the results which we analysed.

Title: Multi touch transparent input output device
Abstract:
In recent years multi-touch interfaces have become popular. They have been giving a new way of human interaction. Multi-touch interfaces can be used in various aspects of human lives, such as medicine, education, military, science etc. The main aim of this project is to build a transparent display device, which uses multi-touch interface. Transparent display is a future trend in a technology world, setting out first in sci-fi movies and turning into reality nowadays. Usage of such devices is significant. They can be used in cars as a windshield, where a driver can see the GPS information as well as watching what happens on the road. In everyday life we can integrate them in mirrors, so in the morning during tooth-brushing we can check out the news, weather etc.
Regarding medicine and military areas, transparent displays can be used to show real-time interactive information for soldiers and surgeons.
The Prototype has been built by using laser light plane technology for multi touch sensing. An image projected from a projector, IR camera was used to capture the touches. The built-in system is a transparent multi-touch display.

Petteri Nurmi, Energy-efficient Location-awareness on Mobile Devices


<!–Speaker: Peterri Nurmi,  Helsinki Institute for Information Technology HIIT
Date/Time: 12pm-1pm July 29th, 2011
Location: 1.33a Jack Cole, University of St Andrews (directions)–>
Abstract:
Contemporary mobile phones readily support different positioning techniques. In addition to integrated GPS receivers, GSM and WiFi can be used for position estimation, and other sensors such as accelerometers and digital compasses can be used to support positioning, e.g., through dead reckoning or the detection of stationary periods. Selecting which sensor technologies to use for positioning is, however, a non-trivial task as available sensor technologies vary considerably in terms of their energy demand and the accuracy of location estimates. To improve the energy-efficiency of mobile devices and to provide as accurate position estimates as possible, novel on-device positioning technologies together with techniques that select optimal sensor modalities based on positioning accuracy requirements are required. In this talk we first introduce novel GSM and WiFi fingerprinting algorithms that run directly on mobile devices with minimal energy consumption [1]. We also introduce our recent work on minimizing the power consumption of continuous location and trajectory tracking on mobile devices [2].

Mirco Musolesi, Sensing, Understanding and Modelling People using Mobile Phones


<!–Speaker: Mirco Musolesi,  Computer Science, University of St Andrews
Date/Time: 1-2pm July 26th, 2011
Location: 1.33a Jack Cole, University of St Andrews (directions)–>
Abstract:
Mobile phones are increasingly equipped with sensors, such as accelerometers, GPS receivers, proximity sensors and cameras, that can be used to sense and interpret people behaviour in real-time. Novel user-centered sensing applications can be built by exploiting the availability of such technologies in these devices that are part of our everyday experience. Moreover, data extracted from the sensors can also be used to model people behaviour and movement patterns providing a very rich set of multi-dimensional data, which can be extremely useful for social science, marketing and epidemiological studies.
In this talk I will present some of my recent work in this area including the design and implementation of the CenceMe platform, a system that supports the inference of activities and other presence information of individuals using off-the-shelf sensor-enabled phones and of EmotionSense, a system for supporting social psychology research. Finally, I will discuss the issues related to the design of energy-efficient social sensing systems.

Nava Tintarev, Narrative Generation: a case study in assistive technology


<!–Speaker: Nava Tintarev, University of Aberdeen
Date/Time: 1-2pm July 19th, 2011
Location: 1.33a Jack Cole, University of St Andrews (directions)–>
Abstract:
Story-telling, (including personal narrative), is a big part of our personal and social communication. This talk will identify challenges and solutions that look at the generation of narrative for social communication. We describe a way to “automatically” generate personal stories. The stories which are mix of natural language and multimedia, are based on sensor, and other data, collected with a mobile phone. This study will place a particular focus on the natural language generation task of document structuring: segmenting this data into meaningful and distinct events.
About Nava:
Nava Tintarev has worked on applied HCI projects with themes such as explanations in recommender systems, recommendations in a mobile travel scenario, and more recently, natural language generation for assistive technology. Currently, she is working as a Research Fellow at the University of Aberdeen where she is a member of the Natural Language Generation Group. She has been working on the “How was School today…?” project, which helps children with complex communication needs create and tell a story about their day at school (which will be the applied setting for the talk on the 19th of July). Before that, she was at Telefónica Research, Barcelona, working on user-centred issues in recommender systems.
Her doctoral thesis focused on explanations for recommender systems, and one of her papers on the topic won her the James Chen best student paper award at the International Conference on Hypermedia (2008). For the last three years she has also been co-organizing a workshop on explanation-aware computing (ExaCt) (http://exact2011.workshop.hm/).
