How can we use new technological advances to develop novel solutions for health and social care? My research explores this question across different populations (older people, people with a learning disability, autistic people, people with dizziness) and across a range of technologies (bespoke to mainstream). 

Some of my current projects include: understanding digital exclusion, smart devices to improve wellbeing, agency and social connectivity for older people and people with a learning disability, virtual/Augmented reality and video games for people with chronic dizziness (in particular, persistent postural perceptual dizziness, PPPD, or ‘visual vertigo’), and multi-sensory environments for Autistic people and people with a learning disability. 

I use a mixed-methods approach that combines qualitative and quantitative measures, observational studies, neuroimaging, and psychophysics. I work closely with practitioners, social care organisations and people with lived experience to co-develop my research projects. 

















‘Smart Speaker’ personal assistants in social care settings

Can new ‘Smart Speaker’ technologies, such as the Amazon Echo and Google Home, improve wellbeing, independence, communication and safety in social care? My Health and Care Research Wales Fellowship is investigating this question for older adults and people with learning disabilities.

Smart technology is becoming increasingly ubiquitous in modern day life, and social care could capitalise on these advances to find novel solutions to models of support. Mainstream smart technologies allow people to control their home environment via voice commands, are cost-effective, and continue to evolve and improve. The two main goals of my fellowship are to:

  1. Improve wellbeing, independence, communication, and safety for vulnerable individuals - ranging from those who wish to remain living independently for longer to those who currently need a high degree of support.
  2. Produce an evidence-base to allow future social care decisions to capitalise on emerging smart technology.

In collaboration with social care organisations across South Wales, I will investigate whether introducing smart technologies into social care settings can improve independence, communication, and wellbeing of individuals receiving support.

Persistent Postural Perceptual Dizziness (PPPD, or ‘visual vertigo’)

Persistent postural perceptual dizziness (PPPD) is a chronic, debilitating condition that describes dizziness and non-spinning vertigo induced by self-movement, challenging visual environments and upright posture. Common triggers include situations of vestibulo-visual conflict, such as cinemas, and intense visual environments, such as supermarkets.

The Cardiff PPPD project is investigating the causes and correlates of PPPD and developing new technological rehabilitation tools for patients. We are collaborating with vestibular clinicians at University Hospital Wales and exploring the enigma of PPPD using a range of theoretical and methodological approaches.  Our research so far has shown that symptoms of PPPD are remarkably common in the general population and that the condition is associated with avoidance and sensitivity across all senses (i.e. not just limited to vision and vestibular).

If you are a clinician and would like to access our videos showing environments that are potential triggers for PPPD, please visit the Cardiff PPPD project webpage.

Sensory perception in Autism Spectrum Disorders

Individuals with ASD often have different sensory experiences of the world than individuals without ASD. This is apparent both from questionnaire measures of sensory processing and from psychophysical measures of differences in detection and discrimination of sensory stimuli. I’m interested in why individuals with ASD have different sensory experiences of the world and the relationship between sensory processing profiles (measured by questionnaires and psychophysics) and real life sensory behaviours and exploration.

In collaboration with Catherine Jones, I’m investigating how multi-sensory environments (MSE; also called Snoezelen® or sensory rooms) are used by children with ASD. MSEs contain equipment that modify sensory input, usually in the auditory, visual and tactile domains, and are common features of special needs schools.  However, relatively little research has explored their benefits and limitations. We are using a purpose-build MSE which is based at the Cardiff University Centre for Human Developmental Science at the School of Psychology.

In a past project, I investigated whether visual attention control can be improved in children with Autism by playing novel eye-tracking attention control games (see Powell, Wass, Erichsen and Leekam, 2016).
