چکیده

Developing effective urban planning approaches is a major challenge for outdoor and indoor environments. Wayfinding in unfamiliar indoor environments is a prime task which everyone would be encountered. The development of assistive technologies to aid wayfinding is hampered by the lack of reliable and cost-efficient methods providing location information in the environment. We have applied RFID technology as a low-cost and operative approach. Our contribution is the suitable design and placement of digital sign system that can be readily detected by a handheld device. We have simulated the task with an agent-based modeling. The hypothesis of the research is that the wayfinder has a handheld device such as a PDA or a mobile system which receives and responses the signals from digital signs through passive tags. Performance of the simulation showed that the appropriate design of digital signs in an unfamiliar environment would result in a more efficient wayfinding process.

Indoor Navigation by People with Visual Impairment Using a Digital Sign System

There is a need for adaptive technology to enhance indoor wayfinding by visually-impaired people. To address this need, we have developed and tested a Digital Sign System. The hardware and software consist of digitally-encoded signs widely distributed throughout a building, a handheld sign-reader based on an infrared camera, image-processing software, and a talking digital map running on a mobi...

A class of multi-agent discrete hybrid non linearizable systems: Optimal controller design based on quasi-Newton algorithm for a class of sign-undefinite hessian cost functions

 In the present paper, a class of hybrid, nonlinear and non linearizable dynamic systems is considered. The noted dynamic system is generalized to a multi-agent configuration. The interaction of agents is presented based on graph theory and finally, an interaction tensor defines the multi-agent system in leader-follower consensus in order to design a desirable controller for the noted system. A...

Using cognitive agent-based simulation for the evaluation of indoor wayfinding systems

This paper presents a novel approach to simulate human wayfinding behaviour incorporating visual cognition into a software agent for a computer aided evaluation of wayfinding systems in large infrastructures. The proposed approach follows the Sense-Plan-Act paradigm comprised of a model for visual attention, navigation behaviour and pedestrian movement. Stochastic features of perception are inc...

Color Targets: Fiducials to Help Visually Impaired People Find Their Way by Camera Phone

A major challenge faced by the blind and visually impaired population is that of wayfinding—the ability of a person to find his or her way to a given destination. We propose a new wayfinding aid based on a camera cell phone, which is held by the user to find and read aloud specially designed machine-readable signs, which we call color targets, in indoor environments (labeling locations such as ...
