CATCH’s research is focused around co-production which
means that every project we work on will always involve
collaborations with one or more of industry, patients and the
public, charities, NHS, clinicians, social care providers and
local authorities.

Challenge: How do we meet the needs of the growing
number of older people with long-term health conditions,
multi-morbidity, frailty and disability (within current
resources)?
• Identifying people at risk, monitoring, prevention and
early intervention
• Supporting independent living at home
• Supporting self-management

Aim
Our aim was to test whether it is feasible to measure walking speed frequently and unobtrusively in the home and evaluate
whether technology is:
• easy to install
• reliable
• acceptable to older people
• low cost
• Secondary aim: to examine the data for examples of changes in walking speed tracking changes in frailty or health status

Qualitative resultsSummarised data from participant interviews:• Positive responses to the concept of measuring walking speed, receiving feedback on speed and to the design/appearance of the
sensor
• Mixed response on awareness of the sensor in the home
• Negative response to the idea of long-term walking speed measurement
• Positive responses to the notion of health data being shared with others; family most common, also supported living staff andclinicians
![Page 23: Enhancing the lives of older people through digital …...Enhancing the lives of older people through digital health and assistive technologies Prof Mark Hawley Centre for Assistive](https://reader036.vdocuments.net/reader036/viewer/2022081406/5f132198fbec4b05971e67e2/html5/thumbnails/23.jpg)
Walking speed sensor feasibility - Conclusions
• Demonstrated proof-of-concept and acceptability of approach to target population
• People with greater levels of clinical frailty walk more slowly at home
• Short-term feasibility trial – not enough time for changes in frailty status
• Need to demonstrate ability to detect change

AvaChat What we did
• Conducted co-design workshops and a proof-of-concept implementation of an autonomous
virtual agent with natural language processing capabilities
• This formed the basis for video-based scenario testing of acceptability
![Page 32: Enhancing the lives of older people through digital …...Enhancing the lives of older people through digital health and assistive technologies Prof Mark Hawley Centre for Assistive](https://reader036.vdocuments.net/reader036/viewer/2022081406/5f132198fbec4b05971e67e2/html5/thumbnails/32.jpg)
What we found
• Adults with a diagnosis of COPD and health professionals specified 4
priority self-management scenarios for which they would like to receive
support:
• at the time of diagnosis (information provision),
• during acute exacerbations (crisis support),
• during periods of low mood (emotional support),
• and for general self-management (motivation).
