Abstract

Objectives: Nowadays, people are expected to do different tasks in quick succession. Hence, even simple lapses can be frustrating especially when we forgot to bring important things when leaving home. This study proposes a real-time detection and notification system of forgotten items. Methods: The system is composed of a base device and at least one portable device. The base device can detect tagged items which can easily be attached to any vehicle or equipment that can contain multiple items. It comprises an Ultra High Frequency (UHF) - RFID technology which has extended the range of detection, a single board computer or a microcontroller, a pocket WiFi router and a power source or a power supply. Application: Meanwhile, the portable device is a smartphone with a mobile application installed, necessary for control and notification purposes. The user will be notified of the forgotten items through an alert in the mobile application. It will be triggered when the items are no longer detected within 1.5 meters from the base device through a wireless network. Findings: Based on the evaluation results conducted in terms usability and functionality, the proposed system received positive feedbacks from users of the system.
