Published in Cliff Wootton, Developing Quality Metadata, 2009
The vCalendar design is an older standard exchange format for calendar data sponsored by the Internet Mail Consortium (IMC). The iCalendar format is a newer standard for calendar data and is described by RFC 2445. It is based on vCalendar and preserves the signature heading to maintain backwards compatibility.
Development of usable applications featuring QR codes for enhancing interaction and acceptance: a case study
Published in Behaviour & Information Technology, 2023
Rubén Hernando, José A. Macías
Applications intended to read QR codes widely vary depending on the information codified. In most cases, these codes include a URL address, and the app redirects to the device's browser to navigate through the web page. This is the case for some current apps based on city locations or museums (Lee 2017), which use QR codes to include a link to public information sources, allowing the user to scan the code and get additional or location information. In this sense, applications exist to generate QR codes from GPS locations, contact cards, URLs, or text messages. Some examples of such applications are (QRDroid. 2018) and QRafter (Erkam 2017). In the system proposed, the QR-code authoring is carried through a web application. In this sense, existing mobile applications scan the codes and export different kinds of information such as contacts (vCard), calendar events (iCalendar), or text. This is the case for (QRStuff 2018) and other QR-code generators and readers (Educators and Technology 2017), which generate and scan QR codes for unique digital resources in isolation. There are other applications, specifically related to marketing and gaming, where the content of the QR code is presented as augmented items (or reality) (Tsai and Huang 2018) over the real world. The QR code acts as a data container in these systems, placing the element on the camera visualisation. This element is usually either an image or a video. An example of this approach is (Onvert. 2020), which provides an editing application to create content and a mobile application to retrieve them.
