During the evaluation only two researchers were present The mobile device was only used during the evaluation session due to lack of stability 3 5 Helpdesk and Support Technical support was provided on a per component basis with UU acting in most cases as the central partner to co ordinate problem solving and initiating actions to address setup problems and installation issues COGKNOW consortium page 15 of 25 3 5 1 Amsterdam During the tests the technician was present to answer questions and give support when errors occurred The caregiver manual was introduced to the participants and was given to the carer while the interviewer explained the COGKNOW Day Navigator to the PwD After that the manual was kept near to the CHH During our tests it was not used to look things up there was no need to do so because questions could be answered by the interviewer and technician 3 5 2 Belfast As the technical researcher was in attendance for all field tests neither user manual nor help desk were considered necessary as everything was explained in full verbally by the researchers However there was an additional researcher technician available throughout to help with any unforeseen problems This person was based in the lab environment in case any additional equipment was needed It should be noted that after having problems with the monitor during the second user test an additional CHH and non touch screen monitor was

During these interviews it was assessed if patients met the inclusion criteria and also background characteristics and context information were gathered Information was collected for configuring the system for each participant preference for reminders music and also photos and phone numbers for picture dialling The field tests were performed in Amsterdam Belfast and Lulea at different times from end of June until the end of August 2007 with sixteen PwD and their carers During the tests users were trained in using the system prescribed tasks were performed and PwD and carers were interviewed and observed The prototype which was tested in field test 1 consisted of the COGKNOW Server CS the COGKNOW Home Hub CHH the COGKNOW Cognitive Assistant CCA and the COGKNOW Sensorized Home CSH The functionalities that were tested were adate time and part time indication a find mobile device function and pop ups of reminders to support in memory picture dialling function to support communication aradio and music player function to support daily activities and an emergency contact function and pop ups of safety warnings e g when the front door is left open to enhance feelings of safety The CCA also had an audio recording function which allowed the PwD to record bottle necks in using the system Chapter 2 introduces the prototype tested the participants of the field test the timing and the organization of sites

Network between CS CHH and CCA was setup via a DSL router Access Point with DHCP support The CS was connected via a LAN cable the CHH and CCA via WLAN For all the devices a fixed IP address was reserved in the access point A fixed phone with large buttons and an old fashioned radio were used 3 1 2 Lulea The CHH software was downloaded and installed without any major problems using the Installation Manual for guidance The CCA software from MOBI was installed in the first mobile device after a lot of trial and error A second pre configured device from MobiSolutions worked once then failed to start the CCA application For the sixth and last user CCA 1 2 6 installation succeeded The following information is not in the installation manual Annex B COGKNOW consortium page 11 of 25 The IP network was created using a WiFi access point The server was connected using a LAN cable The Home Hub and the mobile device were connected using the wireless network WiFi with encryption enabled The server and the Home Hub had fixed IP addresses while the mobile device had a dynamic IP address from the access point Simple external speakers were added to each test system since the speakers of the touch screen did not provide sufficient audio quality for playing music A fixed telephone and a simple radio adapted to elderly people were included A selection of music that is popular among older people in Sweden was compiled and
