ABSTRACT
Due to the spread of COVID-19, people are starting to be more aware and careful when touching any devices in public. To reduce physical contact with public devices, we have developed a method that enables users to interact with many kinds of public devices using the browser on their smartphones. This method is called Chameleon because it resembles the ability of the animal chameleon to change its color according to its surrounding environment. We have developed the prototype system to confirm the mechanism of Chameleon. Then, we have applied the Chameleon method to two practical systems in the campus of Nagasaki University that is expected to be used by multiple users. These two systems are a Certificate Issuance System for students and a Digital Signage System, that provides directions to campus visitors. Through these experiences, we confirmed the availability of the Chameleon method as the new type of the browser included not only Web server browsing functions but also public device operation functions.

ABSTRACT
Due to the spread of COVID-19, people are starting to be more aware and careful when touching any devices in the public. In this paper, we proposed a method that could help reduce physical contacts with public devices using smartphone. This method is called Chameleon and we have developed the Chameleon so that it functions as an application that can control any kinds of public devices with minimal modifications.To confirm the effectiveness of the Chameleon, we have applied the method to two different systems in the campus of Nagasaki University that is expected to be used by multiple users. The two systems are a Digital Signage System, a system that provides directions to campus visitors, and a PIN type Smart Lock, a system that acts as a door lock. © 2021 IEEE.
ABSTRACT
Due to the spread of new coronavirus infections, it is desirable to allow people to use public devices such as PIN type smart locks or vending machines without touching them directly. Therefore, we developed a method that enables contactless operation of various public devices using personal smartphones while reducing the impact on existing public devices. This method imitates chameleons of the animal. Therefore, we call it chameleon. We developed the chameleon based on Web application and applied it to PIN type smart locks. Then, we confirmed the effectiveness of the chameleon as the method of contactless operation. © 2021 IEEE.
