New technology for interactive CAL: The origami project
Origami is a threeâyear EPSRC project that forms part of a general research programme on humanâcomputer interaction. The goal of this research is to investigate and implement new methods for humanâcomputer interaction, and to apply and evaluate their use. The research centres on the DigitalDesk, an ordinary desk augmented with a computer display using projection television and a video camera to monitor inputs. The DigitalDesk allows electronic and printed documents to be combined to give richer presentation and interaction possibilities than are possible with either separate medium. This paper examines the implications of such a system for CAL, and presents two prototype applications that demonstrate the possibilities
Paper-based Mixed Reality Sketch Augmentation as a Conceptual Design Support Tool
This undergraduate student paper explores usage of mixed reality techniques as support tools for conceptual design. A proof-of-concept was developed to illustrate this principle. Using this as an example, a small group of designers was interviewed to determine their views on the use of this technology. These interviews are the main contribution of this paper. Several interesting applications were determined, suggesting possible usage in a wide range of domains. Paper-based sketching, mixed reality and sketch augmentation techniques complement each other, and the combination results in a highly intuitive interface
Analyzing the Impact of Visitors on Page Views with Google Analytics
This paper develops a flexible methodology to analyze the effectiveness of
different variables on various dependent variables which all are times series
and especially shows how to use a time series regression on one of the most
important and primary index (page views per visit) on Google analytic and in
conjunction it shows how to use the most suitable data to gain a more accurate
result. Search engine visitors have a variety of impact on page views which
cannot be described by single regression. On one hand referral visitors are
well-fitted on linear regression with low impact. On the other hand, direct
visitors made a huge impact on page views. The higher connection speed does not
simply imply higher impact on page views and the content of web page and the
territory of visitors can help connection speed to describe user behavior.
Returning visitors have some similarities with direct visitors.Comment: 32 pages,16 table, 10 figur
