Memory and accurate processing brain rehabilitation for the elderly: LEGO robot and iPad case study

Area of Science:

• Gerontology
• Cognitive Science
• Human-Computer Interaction

Background:

• Cognitive decline and memory impairment are significant concerns in the elderly population.
• Developing engaging and accessible tools for cognitive training is crucial for maintaining quality of life in older adults.
• Technology integration offers novel approaches to support cognitive health in seniors.

Purpose of the Study:

• To evaluate the effectiveness and usability of a cognitive therapy system for elderly individuals with mild impairments.
• To assess the impact of iPad-based and interactive LEGO robot exercises on memory and mathematical problem-solving skills.
• To identify user experience challenges and areas for improvement in technology designed for seniors.

Main Methods:

• Development of a cognitive therapy system programmed on an iPad, with options for tablet-only or interactive LEGO robot use.
• Recruitment and testing of a small cohort of elderly participants (2 men, 7 women, aged 65+) with slight physical and cognitive impairment.
• Usability evaluation using the System Usability Scale (SUS) and overall satisfaction scores.

Main Results:

• The System Usability Scale (SUS) yielded a mean score of 48.45 (SD=5.82), indicating potential usability challenges.
• Participants reported a high overall satisfaction score of 84.37 (SD=18.6).
• Elderly users experienced difficulties with touch screen interaction, primarily due to visual impairments and clicking accuracy.

Conclusions:

• The cognitive therapy system shows promise for engaging seniors, evidenced by high overall satisfaction.
• Usability issues related to visual difficulties and motor control necessitate design modifications for this demographic.
• Future iterations should prioritize enhanced visual contrast and minimize reliance on keyboard input for improved accessibility.
