Preparing Teachers for Medical Education Using ICT: Achievements and Challenges of an Educational Intervention in a National University in Perú

摘要

Information gathering system is focused to manage servicestatus in public transportation. Smartphones are first candi-date devices for this purpose because they have an internetconnection through a cellular network. Participatory sensingmethods, where many common people collaborate to collectinformation on their own smartphone, have been focused oninformation gathering. A sensing system requests participantsto collect demanded information. On the contrary, they may notbe enough to collect information continuously because ordinarypeople may not exist in a service area. This paper proposes a collaborative mechanism with BLEdevices with sensors and smartphones to realize the informationgathering system. The proposed mechanism employs BluetoothLow Energy (BLE) devices as a beacon device that triggers ourspecial application for smartphones. BLE devices also storedemanded information with sensors. The special applicationcan be automatically launched when a beacon message arriveson the smartphone and can obtain the demanded informationfrom the BLE device. The benefit of the proposed system isa hands-free operation of the smartphone application becausethe information gathering process is performed in a backgroundprocess. Experimental results demonstrate that the developedapplication can measure its position with a GPS receiver andcan upload the obtained location to the cloud automatically.
