Title: Showing Real-time Recommendations to explore the stages of Reflection and action Authors: Aseniero, Bon Adriel; Tang, Anthony; Carpendale, Sheelagh; Greenberg, Saul Abstract: The majority of Personal Informatics (PI) tools which use Ubiquitous Computing (UbiComp) devices are focused on the collection stage of PI as described by Li et al. [4]. However, tools supporting the reflection and action stages with UbiComp are underexplored. To date, tools for reflection are mostly limited to visualisations of prior performance of an individual, and how to support action is still very much in debate. In this work, we explore how reflection and action might be supported through UbiComp and HCI techniques. We implemented Tip-Me-lens; a prototype designed for exploring and understanding recommendations based on PI data in context. It uses AR tags to differentiate between products; while a mobile device and its camera act as a magic lens which visually overlays digital and real-world browsing. It acts as a futuristic grocery shopping tool that displays recommendations on-the-go as they relate to one’s dietary goals.

Title: Visualizing highly multidimensional time varying Microseismic Events Authors: Mostafa, Ahmed; Carpendale, Sheelagh; Brazil, Emilio; Eaton, David; Sharlin, Ehud; Costa Sousa, Mario Abstract: Making decisions about improving an oil and gas reservoir model based upon microseismic data is a difficult challenge for reservoir engineers and analysts. These difficulties arise because the available data contains inaccuracies, has high-dimensionality and has a high degree of uncertainty. Currently these difficulties are intensified by the lack of computational tools to support interactive visual interpretation and integration of geophysical data leading to robust structural models of the reservoir and its parameters. To address these difficulties domain experts are demanding better and more detailed visualization tools to help them as they explore their data. In this paper, we present a tool that contains a set of interactive visualizations that combines, merges and extends existing visualization techniques. We describe the iterative design process we undertook to develop the tool, relying on insight from domain specialists. Our tool supports 3D spatial analysis and exploration of the data with a set of manipulations designed to provide domain experts with insights into their highly complex microseismic data. Our microseismic visual-analysis tool also provides an extended parallel coordinates implementation to: (1) support interactive filtering and selection through combined filter and shadow boxes that can remove the uninteresting events from further analysis, (2) correlate between the data attributes by axes reordering and outlier discovery, and (3) visually correlate the data events rendering through additional visual elements such as color maps. Our multiple coordinated views link the insights gained from one view with other views instantaneously. We conclude with a discussion of the feedback provided to us by the domain experts.

Title: SPALENDAR: Visualizing a Group’s Calendar Events over a Geographic Space on a Public Display Authors: Chen, Xiang 'Anthony'; Boring, Sebastian; Carpendale, Sheelagh; Tang, Anthony; Greenberg, Saul Abstract: Portable paper calendars (i.e., day planners and organizers) have greatly influenced the design of group electronic calendars. Both use time units (hours/days/weeks/etc.) to organize visuals, with useful information (e.g., event types, locations, attendees) usually presented as - perhaps abbreviated or even hidden - text fields within those time units. The problem is that, for a group, this visual sorting of individual events into time buckets conveys only limited information about the social network of people. For example, people’s whereabouts cannot be read ‘at a glance’ but require examining the text. Our goal is to explore an alternate visualization that can reflect and illustrate group members’ calendar events. Our main idea is to display the group’s calendar events as spatiotemporal activities occurring over a geographic space animated over time, all presented on a highly interactive public display. In particular, our SPALENDAR (SPAtial CALENDAR) design animates peoples’ past, present and forthcoming movements between event locations as well as their static locations. Details of people’s events, their movements and their locations are progressively revealed and controlled by the viewer’s proximity to the display, their identity, and their gestural interactions with it, all of which are tracked by the public display.
