This thesis describes the design and development of a tech platform where a mobile application creates slideshows from multimedia content uploaded in a web application titled “Multimedia Slideshow Maker” (MSM). The project is carried out for an external partner, Alight AS, for a project called Alight. Alight is a mobile tech platform aiding caregivers in sending personalised video sessions to patients with dementia. This thesis aims to determine to what degree MSM can be used independently by a caregiver, without instructions from others or prior experience in video editing. MSM was designed and developed in iterations based on feedback from experienced evaluators and tested with end-users. The system has been compared to similar applications, where both strengths and limitations of MSM were discovered. The test results showed several usability problems, where solutions to each problem are discussed. Participants were to a large extent able to use MSM without instructions from others, where MSM enabled them to create a multimedia slideshow without requiring experience in video editing. The sample size, however, might not account for all differences in abilities among caregivers.
