Abstract

The contributions of this thesis are situated in the field of Human-Computer Interactions (HCIs), a field "concerned with the design, evaluation and implementation of interactive computing systems for human use and with the study of major phenomena surrounding them" [Hewett et al., 2014]. Each of the main contributions presented in this thesis is substantiated in one or more observational studies or controlled experiments. All of the studies and experiments were designed, conducted, and analyzed according to widely accepted standards of the HCI community [Lazar, J. H. Feng, and Hochheiser, 2010]. This section describes the general approach to the design and analysis, which applies to all studies presented. Any exceptions are mentioned and justified in the respective chapters. Study DesignIn this thesis, two general types of study designs are applied, controlled experiments and observational studies.

Memoro: Using Large Language Models to Realize a Concise Interface for Real-Time Memory Augmentation

“…Social interactions such as conversations is a setting in which a majority of subjective memory complaints occur [51]. More recently, there has been growing work on real-time information access during conversations to bring filtered information to the user's attention to improve the quality of conversation [2,3,19,37,46,49]. Meurisch et al [46] conducted an in-the-wild study of systems with different proactivity levels.…”

“…Meurisch et al [46] conducted an in-the-wild study of systems with different proactivity levels. Muller et al [49] presented guidelines for the design of user interfaces for conversation support such as to provide means for fluid transition and re-engagement to ease the switch between information retrieval and the conversation. This informed the design of the interaction of Memoro to reduce query time and response duration.…”
