Supporting System for Quick Dementia Screening
  Considering the diagnosis of dementia in the elders, doctors usually need a observation record taken by the elders’ families or caregivers to know the recent behavior of the elders, and it can't be diagnosed quickly if the elders live independently. Therefore, we have developed the “Supporting System for Quick Dementia Screening ”,  the elders only need to perform some assigned activities within a few hours in a smart home environment where many ambient sensors are deployed. From analyzing the sensor data by the system, it can help doctors to assess the elder's likelihood of having dementia in behavior.

Investigation of Dementia and Smart Home
  According to research findings, elders with dementia may have difficulty completing Instrumental Activities of Daily Living (IADL), which means that behaviors of the cognitively healthy (CH) elders may be different from those with dementia.
However, it is difficult to identify the behavior changes by elders themselves because many elders live independently.
Fortunately, advanced technologies nowadays can play an important role to solve this problem. The elders' behavioral information of daily activities can actually be perceived by ambient sensors installed in their homes for long-term monitoring, and those activities at homes can also be recognized with the help from both ambient and wearable sensing under the setting of a developed system.
These technologies in smart home systems can save enormous efforts of the caregiver to monitor elders all day, and these analyzed informatiom is also useful for doctors to diagnose elders more precisely. Nonetheless, these methods still require long-term observation. Many elders are not willing to be monitored long-term, and not willing to put on wearable device all day lone because they feel uncomfortable and have no privacy.

Technical Research Approach and Innovation
  On the basis of the elders with dementia who may have wandering behaviors during the Instrumental Activities of Daily Living (IADL), we have developed a system to detect indoor wandering patterns of the elders only by motion sensors, and it can support doctors to quickly assess the elders' likelihood of having dementia. By the system setting, the elders don't need to wear any device, and it does not record the voices and images of the elders.
  In order to provide the system a sufficient number of samples to build the model, the elders need to be diagnosed by doctors first to let system know whether they are dementia or not; Then, a doctor can use the quick screening for the elders based on the established model.
