“…These tools can substitute prospective memory (memory of actions to do), to ensure that we remember things we intend to do in the future (e.g., using calendar to remember to attend an appointment). New technologies (e.g., smartphones) provide effective reminder tools (e.g., Google calendar [80]) [18,58,59,113]. External memory aids can also substitute retrospective memory (memory of past events), to increase the amount of past events that can be recalled (e.g., by storing pictures in a computer) [18,58].…”

Human memory has notable limitations (e.g., forgetting) which have necessitated a variety of memory aids (e.g., calendars). As we grow closer to mass adoption of everyday Extended Reality (XR), which is frequently leveraging perceptual limitations (e.g., redirected walking), it becomes pertinent to consider how XR could leverage memory limitations (forgetting, distorting, persistence) to induce memory manipulations. As memories highly impact our self-perception, social interactions, and behaviors, there is a pressing need to understand XR Memory Manipulations (XRMMs). We ran three speculative design workshops (n=12), with XR and memory researchers creating 48 XRMM scenarios. Through thematic analysis, we define XRMMs, present a framework of their core components and reveal three classes (at encoding, pre-retrieval, at retrieval). Each class differs in terms of technology (AR, VR) and impact on memory (influencing quality of memories, inducing forgetting, distorting memories). We raise ethical concerns and discuss opportunities of perceptual and memory manipulations in XR. CCS CONCEPTS• Human-centered computing → Virtual reality; Mixed / augmented reality.

“…Virtual reality has been used as a cognitive training tool for people with mild cognitive impairments to simulate typical daily activities [129]. Other immersive technologies like PENCODER rely heavily on experiences and objects that are familiar to people with mild cognitive impairment, and have positively influenced upward trends in self-esteem among participants [110].…”

Clinical researchers have identified sensory changes people with age-related cognitive changes, such as dementia and mild cognitive impairment, experience which are different from typical age-related sensory changes. Technology designers and researchers do not yet have an understanding of how these unique sensory changes affect technology use. This work begins to bridge the gap between the clinical knowledge of sensory changes and technology research and design through interviews with people with mild to moderate dementia, mild cognitive impairment, subjective cognitive decline, and healthcare professionals. This extended version of our ASSETS conference paper includes people with a range of age-related cognitive changes describing changes in vision, hearing, speech, dexterity, proprioception, and smell. We discuss each of these sensory changes and ways to leverage optimal modes of sensory interaction for accessible technology use with existing and emerging technologies. Finally, we discuss how accessible sensory stimulation may change across the spectrum of age-related cognitive changes.
