“…The similarity of wearable camera photographs to the phenomenological experience of autobiographical memory may also drive their benefits. Like autobiographical memories, wearable camera photographs are from a first-person field perspective, are captured unconsciously, are visual, occur in chronological order, are incomplete and fragmentary, and capture brief moments in time [5, 8, 27]. Therefore, they are a highly effective trigger for autobiographical memory recall.…”

“…In these “Proustian moments,” the whole memory for the event is directly retrieved and re-experienced [5, 28, 29]. The photographs may also act as highly specific cues that allow more efficient indirect, voluntary retrieval of events [8, 28]. Overall, the memory benefits of wearable camera photograph review are likely to come from both the high volume of photographs and the nature of the photographs themselves.…”

“…Wearable cameras’ ability to trigger event recall may depend on photograph presentation. Most studies using wearable camera review presented the photographs as time lapse “movies” or rapid slideshows and tested event recall immediately afterward [e.g., 1, 8, 9, 32]. This method requires participants to view the whole event and then recall it afterwards, which may emphasise the temporal sequence of the event.…”

“…Reviewing these photographs appears to trigger recollection of the event itself beyond what is shown in the photographs, such as conversations and emotions [3-5]. Silva et al [8] suggested that this process may even support autobiographical and episodic memory more generally in patients with mild Alzheimer’s disease.…”

Background: Wearable camera photographs have been shown to be an effective memory aid in people with and without memory impairment. Most studies using wearable cameras as a memory aid have presented photographs on a computer monitor and used a written diary or no review as a comparison. In this pioneering study, we took a new and innovative approach to wearable camera photograph review that embeds the photographs within a virtual landscape. This approach may enhance these benefits by reinstating the original environmental context to increase participants' sense of re-experiencing the event. Objective: We compare the traditional computer monitor presentation of wearable camera photographs and actively taken digital photographs with the presentation of wearable camera photographs in a new immersive interface that reinstates the spatiotemporal context. Methods: Healthy older adults wore wearable or took digital photographs during a staged event. The next day and 2 weeks later, they viewed wearable camera photographs on a computer monitor or in context on an immersive interface, or digital photographs. Results: Participants who viewed wearable camera photographs in either format recalled more details during photo viewing and subsequent free recall than participants who viewed digital photographs they had taken themselves. Conclusion: Wearable camera photographs are an effective support for event memory, regardless of whether they are presented in context in an experience-near format.

“…Technological advances offer new methods for supporting people with dementia to manage memory problems, minimise safety risks, and improve quality of life, including electronic pill dispenser boxes, electronic diaries, wearable cameras (e.g., Silva, Pinho, Macedo, & Moulin, 2017), interactive 'pet' robots (e.g., Moyle et al, 2017, tracking devices, and fall sensors. Although these methods are promising, most existing studies are limited by small samples, unreliable technology, conduct outside the home environment, and outcomes unrelated to everyday function and quality of life (Fleming & Sum, 2014;King & Dwan, 2017;van der Roest, Wenborn, Pastink, Dröes, & Orrell, 2017).…”

Introduction and Preliminary ConsiderationsDementia afflicts almost 50 million worldwide (Prince et al., 2015), is the greatest cause of disability in people aged over 65 (Australian Institute of Health and Welfare, 2012), and a leading cause of death in Western countries (Australian Bureau of Statistics, 2016). It substantially impacts family and caregivers, and has a vast economic impact (e.g. > US $950 billion worldwide, Jia et al., 2018). Yet, it is likely to become an even bigger issue, with prevalence anticipated to nearly triple by 2050 (Prince et al., 2015), as survival age increases worldwide. Despite this, dementia remains the only disease within the ten most prevalent causes of death without a reliable method of prevention or cure (Alzheimer's Association, 2017).Alzheimer's disease (AD) is the most common cause of dementia (60-80%; Alzheimer's Association, 2017); and, with the advent of reliable biomarkers, it is clear that AD starts long before dementia is diagnosed. Indeed, AD is now considered a continuum with dementia as the end stage (Jack et al., 2018). Therefore, we will consider the spectrum of AD presentations, from preclinical stages (including subjective cognitive decline, SCD), through the prodromal mild cognitive impairment (MCI) stage, and finally the dementia stage (see Figure 1).
