1.Research Questions for Smart City I decided to go back to Smart City and rethink Research questions for good research. So I read an article or report to identify the trends of smart cities. There are many interesting examples of smart cities. Previously, I was interested in smart mobility. So I read many articles and […]

1.Using Open Source I analyzed the code today to see how open source code uses sensors. *UML 2. Studying JAVA And because it is Java based code, additionally I watched Java related videos and studied. https://opentutorials.org/module/516/5261 *Link https://postechackr-my.sharepoint.com/personal/juhpark_postech_ac_kr/_layouts/15/onedrive.aspx?id=%2Fpersonal%2Fjuhpark%5Fpostech%5Fac%5Fkr%2FDocuments%2FPDI%20Lab%2FChang%20Mi%2F0813

1.Simplified data using sensors in smartphone. As an open source, I checked and studied the code to obtain sensor data through a smartphone. 2.Detailed data about location using GPS Logger. Through the code provided by the GPS Logger, detailed data about the location can be obtained from the sensors on the smartphone. It also has […]

Scooter-sharing system A scooter-sharing system is a service in which scooters are made available to use for short-term rentals. The term describes the sharing of mostly electric motor scooters (also referred to as electric mopeds) as well as electric kick scooters. The sharing of scooters is  similar to carsharing or bicycle-sharing systems; with some scooter-sharing companies offering more than one type of […]

UX is not a new phenomenon.  It has been around since the moment humans began to interact with tools and machines. It is found in everything that humans touch — ranging from tangible objects, such as a can opener, to the seamless experience of Amazon’s “1-Click” feature. *Reference : https://uxdesign.cc/who-are-the-founding-fathers-of-ux-design-e41158dbc6e5 The History of UX Design […]

GPSLogger for Android The location information can be obtained more easily than the GNSS Logger. And if you set it for your convenience, you can set upload time every 5 minutes, every 10 minutes. GPSLogger uses the GPS capabilities of your Android phone to log coordinates to GPS format files at regular intervals. The purpose […]

Additional information for interpreting graph The pseudoranges of Clocks column The pseudorange (from pseudo- and range) is the pseudo distance between a satellite and a navigation satellite receiver for instance Global Positioning System (GPS) receivers. To determine its position, a satellite navigation receiver will determine the ranges to (at least) four satellites as well as their positions at time of transmitting. Knowing the satellites’ orbital parameters, these […]
