We propose a support system for finding lost objects indoors. The system employs active RFID and ultrasonic position detection to detect the position of a lost object. The system illuminates the position by using Movinglight, which is normally employed in stage lighting. From an experiment, the way of notification by light is better than that by sound in some situations.

Method for estimation of distance between objects and its application for finding lost objects
TLDR
A method to estimate the distance between objects rather than the individual object locations without using a method to obtain location-dependant information is proposed.
A Navigation System Using Ultrasonic Directional Speaker with Rotating Base
TLDR
New method for object reference which enables a person to find surrounding objects and develops a navigation system named CoCo, which navigates a people to an object using position data from an object management system.
Simply tag and find: finding indoor items by using detection history of RFID tags
TLDR
A novel method for locating tagged items that uses a RFID reader, a smartphone, and unregistered RFID tags attached to a variety of items, furniture and places and suggests that the method is effective for location target RFID-tagged items.
IteMinder: finding items in a room using passive RFID tags and an autonomous robot (poster)
TLDR
A novel search technique called IteMinder that helps users find property in a room using passive RFID and an autonomous robot and uploads the tag ID and location information to the database.
An Improved and Cost Effective Radio Frequency based Object Detection System
TLDR
This paper attempts to design and implement an object detection system that when produced in large quantity can be affordable by the majority and provide solutions to the short-range problem experienced in the existing systems, thereby eliminating the stress of finding lost items in homes.
Destination Board System Based on Photographs
TLDR
The results show that visitors often recognize the user's current location from the photograph and sometimes leave some graffiti on the image.
Design and Implementation of a Dual-Camera Wireless Sensor Network for Object Retrieval
TLDR
The design and implementation of a dual-camera sensor network that can be used as a memory assistant tool for assisted living performs energy-efficient object detection and recognition of commonly misplaced objects and can seamlessly integrate feedback from the user to improve the robustness of object recognition.
Find my stuff: a search engine for everyday objects
TLDR
Find My Stuff (FiMS) is a search engine for physical objects based on SmartFurniture equipped with RFID readers and ZigBee modules that offers the users a simple search interface to locate tagged physical items in different indoor environments.
Find my stuff: supporting physical objects search with relative positioning
TLDR
Functional evaluation of the prototype shows the approach's practicality with sufficient accuracy in realistic environments and low energy consumption, and two user studies showed that objects can be retrieved significantly faster with FiMS than manual search and that relative position cues provide better support than map-based cues.
Develop An Indoor Space Ontology For Finding Lost Properties for Location-Based Service of Smart City
TLDR
An indoor space ontology model for finding the indoor lost property is developed and both static and dynamic location information is presented for assisting BLE devices, users, and lost property.

SearchLight - A Lightweight Search Function for Pervasive Environments
TLDR
The scenario of finding books in a library or office environment and several extensions currently under development are discussed, including a lightweight search function for physical objects in instrumented environments.
The location stack: a layered model for location in ubiquitous computing
TLDR
The location stack is presented, a layered software engineering model for location in ubiquitous computing that encourages system designers to think of their applications in this way, to drive location-based computing toward a common vocabulary and standard infrastructure.
