Designing technology that provides step-by-step guidance can significantly aid individuals with dementia in completing multi-step tasks, addressing cognitive deficits like sequencing and memory. This human factors research insight is drawn from a 2008 study published in White Rose eTheses Online (University of Leeds, The University of Sheffield, University of York). Using Qualitative research using grounded theory analysis (gta) with 22 professional carers/occupational therapists and 8 individuals with dementia and their caregivers., researchers explored how this design variable affects real-world outcomes. The key design takeaway: Design assistive technologies that break down complex tasks into manageable steps, providing timely and context-aware prompts to support individuals with cognitive impairments.
Assistive technology prompts can improve task completion for individuals with mild to moderate dementia.

Key Findings
- 01Individuals with dementia experience difficulties with daily activities, domestic tasks, leisure, and interpersonal interactions due to underlying deficits in sequencing and memory/orientation.
- 02Assistive technology should be designed to support sequencing and memory, thereby improving physical wellbeing and a sense of control for the person with dementia, and reducing care demands on informal caregivers.
- 03Verbal cues and situated factors play a role in task completion and should be considered in technology design.
Application
Design takeaway
Design assistive technologies that break down complex tasks into manageable steps, providing timely and context-aware prompts to support individuals with cognitive impairments.
How to apply
When designing any product or system intended for users with cognitive impairments, prioritize simplicity, clarity, and step-by-step guidance. Test prototypes with the target user group to ensure prompts are effective and not overwhelming.
Project actions
- 01When researching user needs, consider the specific cognitive challenges your target users face.
- 02Think about how to break down complex tasks into simpler steps for your design.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Employs a robust qualitative methodology (Grounded Theory) to deeply understand user needs.
- +Includes perspectives from both professional caregivers and individuals with dementia.
Limitations
The sample size might be small, and the specific types of dementia and their progression can vary greatly.
Reliability & validity
The use of Grounded Theory provides rich, in-depth data, enhancing validity. However, the qualitative nature and specific sample may limit generalizability, impacting external validity.
Think critically
How might the effectiveness of these prompts change as the severity of dementia progresses?
Design Principles
"Cognitive scaffolding: Design systems that provide external support to compensate for internal cognitive deficits, enabling task completion and promoting user independence."
Understanding the specific cognitive challenges faced by individuals with dementia is crucial for developing effective assistive technologies. This research highlights the need for user-centred design that directly addresses deficits in sequencing and memory to promote independence and reduce caregiver burden.
What This Means for Your Design
Technology that gives step-by-step instructions can help people with memory problems complete everyday tasks better.
