The level of cognitive impairment must be taken into account in the design of technology because people with severe dementia have different needs vs. mild dementia.
Explanation and Example
People with severe cognitive impairment will have more problems learning to use different and new devices. They need more explanation and a longer learning time, due to limited cognitive capacities. For example, the clinical experience with Gradior shows that people with moderate and severe dementia should have the therapist as a permanent guide. According to this, Gradior possibly would have to adopt new systems and tools to become effective in people with moderate and severe dementia, and in turn, allow a level of autonomy of the person with dementia who uses this technology. Indeed, the help of a therapist in the first steps of applying a technological-based therapy is strategic for implementing and accepting the approach.
