It differs from more simple metric collection in that it typically involves interaction with services.
The objectives include: identifying and tracking persons or objects in the scene or the interpretation of user gestures for interaction with services, devices and systems implemented in the digital home.
One of the challenges associated with increasing language access to services is that services themselves need to adapt to a situation in which health care users may become more vocal in interaction with services, so all interventions have to be explored with respect their organisational dimensions as well with respect to the purely linguistic dimensions.
But for many of those who declined to use similar technology in similar places when it was repeatedly tried over the last 20 years, the main appeal of the machines is the chance to avoid what they say are increasingly frequent frustrating, hostile or guilt-inducing interactions with service workers.
Economists, psychologists and sociologists have charted our ballooning work hours; the increase in time devoted to competitive shopping; the commercialization of leisure that turns fun into work and requires military-scale budgeting and logistics and emotionally draining interactions with service personnel.
The impact of staff perceptions of daily work pressures on burnout requires further exploration because both issues may be adversely affecting the quality of staff interactions with service users.
Negative perceptions stemmed primarily from interactions with service staff and the availability of resources, rather than the condition or accessibility of facilities.
Carers' experiences of their carer role were also explored, in order to provide a context for their interactions with service providers.
For example, in interview 2, carers were asked to clarify the services they had been using (and had documented in the service usage diary) and to expand on their interactions with service providers.
