Aging services technology study identifies available technologies for Cognitive Impairment and evidence of their benefits.
On page 69 the GPS Shoe is identified as a solution and discusses GPS monitoring technology:
In addition to their utility in detecting cognitive impairment, activity-monitoring technologies have also been used among people with established cognitive deficits. One example of this application is among patients who engage in dangerous behaviors such as wandering and elopement (Altus et al., 2000). Monitoring technologies mitigate the risks associated with these behaviors by facilitating remote patient monitoring. This approach not only provides physical security to the patient, but it also provides emotional security to caregivers and reduces caregiver burden by allowing the caregiver to monitor a loved one from a location of their choosing. A variety of technologies can be employed in patient monitoring systems. These include global positioning systems (GPS), radio frequency (RF) transmitters, and cellular-based tracking devices. In one system, a GPS is embedded in shoes that allow the user’s location to be tracked with a secure subscriber’s portal. Other systems integrate more than one technology to address these behaviors. Assisted GPS systems (AGPS), which combine GPS and cellular tracking functionalities, can provide greater accuracy, availability, and coverage than standard GPS (Djuknic and Richton, 2001).
