NeverMind : an interface for human Memory augmentation

Abstract

If we are to understand human-level intelligence, we need to understand how memories are encoded, stored and retrieved. In this thesis, I take a step towards that understanding by focusing on a high-level interpretation of the relationship between episodic memory formation and spatial navigation. On the basis of the biologically inspired process, I focus on the implementation of NeverMind, an augmented reality (AR) interface designed to help people memorize effectively. Early experiments conducted with a prototype of NeverMind suggest that the long-term memory recall accuracy of sequences of items is nearly tripled compared to paper-based memorization tasks. For this thesis, I suggest that we can trigger episodic memory for tasks that we normally associate with semantic memory, by using interfaces to passively stimulate the hippocampus, the entorhinal cortex, and the neocortex. Inspired by the methods currently used by memory champions, NeverMind facilitates memory encoding by engaging in hippocampal activation and promoting task-specific neural firing. NeverMind pairs spatial navigation with visual cues to make memorization tasks effective and enjoyable. The contributions of this thesis are twofold: first, I developed NeverMind, a tool to facilitate memorization through a single exposure by biasing our minds into using episodic memory. When studying, we tend to use semantic memory and encoding through repetition; however, by using augmented reality interfaces we can manipulate how our brain encodes information and memorize long term content with a single exposure, making a memory champion technique accessible to anyone. Second, I provide an open-source platform for researchers to conduct high-level experiments on episodic memory and spatial navigation. In this thesis I suggest that digital user interfaces can be used as a tool to gather insights on how human memory works.
