We present a preliminary experiment to understand the variability of six simple movements. Six participants, wearing inertial measurement units on their wrist, performed six actions. The data collected were analysed using time-delay embedding theorem, PCA and percentage of cumulative energy to characterise variability in these movements. Of these movements, circular and 8-shape movements show a constant trend between participants; however, such a trend is not evident for static, horizontal, vertical and diagonal movements. Such analysis can be useful in determining different states of interactions with the display of user’s behaviour (enthusiasm, boredom, tiredness or confusion) over the course of training, practice or rehabilitation.

The Fifth ACM International Symposium on Pervasive Displays will take place in June 2016 in Oulu, Finland.The symposium on Pervasive Displays welcomes work on all areas pertaining to digital displays including, but not limited to: Applications, Content design, Evaluations, case studies, deployments and experience reports, Interfaces and interaction techniques, Novel technologies and new forms of pervasive display, System architectures and infrastructure, Research methods for pervasive displays, Media facades and architecture and Art installations.
We invite you to begin planning your submissions and participation for PerDis 2016!
The poster track presents an opportunity to publish late-breaking results, technical descriptions, smaller research contributions, and works-in-progress in a concise format. Accepted posters will be displayed in a designated session, providing presenters with an opportunity to engage in discussions with other attendees around their research.
Authors are required to submit an abstract and draft poster. Poster abstracts should be a maximum of two (2) pages in ACM SIGCHI format, clearly describing the research questions addressed, research methods and tasks, findings or results, and the contribution to the pervasive displays community. Abstracts should also provide sufficient background and related work to situate and contextualize the authors work within the greater body of research. As the abstract may be viewed without the poster, this should be written to stand alone as an independent submission. Draft posters should be formatted for A1 portrait (594mmx841mm).
Submissions should consist of original work not been previously published or concurrently under consideration for any other conference, workshop, journal, or other publication with an ISBN, ISSN or DOI number.
All submissions (and supplementary material) should not be anonymized and will be reviewed by an international panel of experts in the field of pervasive displays. All accepted abstracts will be archived in the ACM Digital Library.
