Intuitive Interaction Framework in User-Product Interaction for People Living with Dementia

Abstract

This chapter is focused on intuitive interaction with various interfaces for people living with dementia. First, we describe the enhanced intuitive interaction framework, which contains a continuum suggesting various pathways to intuitive use that can be included in the design of interfaces. We discuss how it relates to users, and specifically how it may assist users living with dementia. Then three empirical studies conducted over two continents are discussed. Each involved participants living with dementia using interfaces in a lab. Data were analyzed for task completion, reaction times and completion times (Studies 1 and 2), and presence and effectiveness of physical and perceived affordances (two of the proposed pathways to intuitive use on the EFII continuum). These data were then compared according to the enhanced intuitive interaction framework, and the findings suggested that employing interface features that are more familiar and more ubiquitous for the target population would likely make the interfaces more intuitive for people living with dementia to use.

Designing for Everyday Sounds at Home with People with Dementia and their Partners

“…The mockups were not intended to steer aesthetic or form-related design choices but to enable people with dementia to express their opinions on the functionality and interactions with sounds. The mockups were based on iconic or recognizable music devices, such as a music box [53], radio [95], and record player [89], as these can be more easily recognized and spark interaction in people with dementia [12,53,72,89,95]. Participants could play their everyday sounds with the music box by opening the lid and stop playing the audio by closing it.…”

“…A user can easily play everyday sounds by rolling, tilting, or shaking the device (see Figure 8). Objects with physical afordances that involve object manipulations provide more intuitive interactions for people with dementia [12]. Like 'rolling a dice', the Tumbler avoids complex cognitive tasks as the surprising nature of the interaction supports the discovery of sounds where users cannot make any mistakes.…”

Interface Design for Products for Users with Advanced Age and Cognitive Impairment

“…Blackler et al [ 16 ] explored intuitive interaction with various interfaces for people living with dementia. In their study, a usability test of six types of microwave interfaces for adjusting cooking power (see Figure 2 ) was conducted to examine the relationship between intuitive interactions in product interfaces among older people with dementia.…”

“… Test interfaces for adjusting cooking power [ 16 ]. Interfaces ( A , B , F ) were operated by pressing buttons at the bottom of the interface to cycle through the available power settings.…”

Supporting people with dementia- Understanding their interactions with Mixed Reality Technologies

“…Metaphors or idioms or population stereotypes are difficult for PwD to process and reason the meaning out of them. Physical affordances on the other hand offer natural and intuitive form of interaction for PwD (Blackler, Li-Hao, Desai, & Astell, 2020). The speed at which prompts are perceived and actions executed, will determine ongoing engagement of PwDs in IADL.…”
