In this short paper we introduce graffiti in public restrooms – also known as latrinalia – as a promising object of research. We present an application that uses crowdsourcing techniques to upload and transcribe images of latrinalia on a public web site. This article describes the basic design and functions of the application, presents the status quo of the current dataset, and also gives an ou...

Acknowledgements The data used in this paper is that of Professor Cintron. Some he collected before I began my assistanship, and the rest was collected after January, 1991. Many of my observations in this paper have come from my year of working with Professor Cintron. Observations arose in conversation or sometimes in writing, but it is difficult to footnote the exact source. I highly recomend ...

Abstract The generation of boat and ship imagery in the form graffiti has long precedents internationally. Such carries with it a range context-dependant associations meanings. This paper presents collection previously undescribed from north coast Ireland which demonstrates features behaviours parallel those witnessed wide chronological situations elsewhere, while retaining context-specific res...

Residents within a council housing area in Stirling, Scotland, which is undergoing regeneration, took photos for an auto-driven photo-elicitation study. There was limited guidance on what images to capture. were simply invited focus the neighbourhood. An unexpected finding significance participating residents gave linguistic and semiotic landscape such as signs, billboards graffiti. Within inte...

We describe a method for recognizing the regular characters drawn by hand gestures or by a pointer on the forearm of the user captured by a head mounted camera for wearable computing. We assume that each character is drawn by a single stroke and in an isolated manner as in Graffiti. Recognition is performed by a bank of finite state machines whose input is the chain code of the hand drawn chara...

We discuss a conjecture of J. R. Griggs relating the maximum number of leaves in a spanning tree of a simple, connected graph to the order and independence number of the graph. We prove a generalization of this conjecture made by the computer program Graffiti, and discuss other similar conjectures, including several generalizations of the theorem that the independence number of a simple, connec...

We analyze the feedback loop in Tele-Graffiti, a cameraprojector based remote sketching system which we recently developed. We derive the gain through the feedback loop and the final images that will be viewed by the users of the system. We then derive the “optimal gain” as the gain that results in the final viewed images being as close as possible to the sum of the images actually drawn on the...
