title: Capturing Situational Context in an Augmented Memory System

authors: Alallah, Jehan Shoie

abstract: Bookmarking a moment is a new approach being introduced to capture past experience and insert information into an augmented memory system. This idea is inspired from the concept of the bookmark in web browsers. Semi-automatic bookmarking different moments when time is limited and revisiting these moments before inserting them into an augmented memory system will help people to remember their past experience. An exploratory study was conducted to discover and shape the design requirements for a system called CatchIt. It aims to understand end-users’ needs to capture their personal experience, which is an important and complex issue in the case of capture and access of personal experiences. CatchIt is a system to bookmark the significant moments during the day before enriching them, and entering them into the augmented memory system called Digital Parrot. The conceptual design of CatchIt will be the main aim of this study. The primary requirements were derived from the scenarios and analysis of the findings of five different study stages were designed to inspect these: unobserved field visit, shadowing, using indictors, Wizard of Oz and using technology. Thirty participants were involved in field visit, survey and follows up interview. Each stage had different tasks to be performed and the findings of each stage contributed to understanding different parts of user needs and system design requirements. The results of this study indicated the system should automatically record the context information, especially the time and location since they were typically neglected by the participants. Different information such as textual and visual information should be manually recorded based on the users’ setting or situations. A single button is a promising input mechanism to bookmark a moment and it should be fast and effort- less. The result showed no clear correlation between learning style and type of the information that had been captured. Also, we found that there might be a correlation between passive capture and false memories. All these findings were used to provide a foundation for further work to implement the bookmark system and evaluate this approach. Some issues raised in this study need further research. The work will contribute to a greater understanding of human memory and selective capture.

title: The MIREX Grand Challenge: A Framework of Holistic User-Experience Evaluation in Music Information Retrieval

authors: Hu, Xiao

subjects: Science & Technology

abstract: Music Information Retrieval (MIR) evaluation has traditionally focused on system‐centered approaches where components of MIR systems are evaluated against predefined data sets and golden answers (i.e., ground truth). There are two major limitations of such system‐centered evaluation approaches: (a) The evaluation focuses on subtasks in music information retrieval, but not on entire systems and (b) users and their interactions with MIR systems are largely excluded. This article describes the first implementation of a holistic user‐experience evaluation in MIR, the MIREX Grand Challenge, where complete MIR systems are evaluated, with user experience being the single overarching goal. It is the first time that complete MIR systems have been evaluated with end users in a realistic scenario. We present the design of the evaluation task, the evaluation criteria and a novel evaluation interface, and the data‐collection platform. This is followed by an analysis of the results, reflection on the experience and lessons learned, and plans for future directions.

title: Ko wai tēnei e tū ake nei? Activating collectivity and accountability through grounded positioning

authors: Rata, Arama

abstract: Building on conference conversations about positionality—about who we are and how our identities shape our views of the world, about the connections and disconnections experienced between us, and about our proximities to place, power, and privilege—this piece brings together four conference participants to continue to reflect on what positionality means, on why it is important, and on how to practice it in non-performative, well-developed, and mutually nourishing ways. Their dialogue reflects active and critical positioning in process and practice, creating opportunities for acknowledging our relationships and activating both collectivity and accountability in the various spaces where we live, work, create, and hope.
