Mild cognitive impairment (MCI) may affect up to 20 % of people over 65 years old. Global incidence of MCI is increasing, and technology is being explored for early intervention. Theories of technology adoption predict that useful and easy to use solutions will have higher rates of adoption, however, these models do not specifically consider older people with cognitive impairments, or the unique human computer interaction challenges posed by MCI. We collated opinions from older people with MCI about technology solutions proposed for them, found in 83 articles published between Jan 2014 and May 2024, and found in nine databases. Inductive, thematic analysis of feedback identified five themes (i) purpose and need, (ii) solution design and ease of use, (iii) self-impression, (iv) lifestyle, and (v) interaction modality. Solutions are perceived as useful, even though gaps in functional support exist, however, they are not perceived as entirely easy to use, due to issues related to usability and user experience. Devices which are light, portable, common and have large screens, are preferred, as is multimodal interaction, in particular speech, visual/text and touch. This review recommends future work to (i) improve usability and user experience, (ii) enhance personalisation, (iii) better understand interaction preferences and effectiveness, (iv) enable options for multimodal interaction, and (v) more seamlessly integrate solutions into users lifestyles.
