title: Use of video shadow for small group interaction awareness on a large interactive display surface

authors: Apperley, Mark

subjects: computer science

abstract: This paper reports work done as part of the Large Interactive Display Surface (LIDS) project at the University of Waikato.  One application of the LIDS equipment is distributed meeting support.  In this context large display surfaces are used as shared workspaces by people at collaborating sites.  A meeting with start with a shared presentation document, typically and agenda document with summary and detail on agenda items as required.  During the meeting, annotations with be made on the shared document, and new pages will be added with notes and drawings. 
To prevent access collisions and generally mediate use of the shared space, mechanisms to provide awareness of actions of people at other sites are required.  In our system a web camera is used to capture a low-resolution image of the person/people near the board on each side.  Rather than transmit the image directly we computed a shadow/silhouette.  The shadow is displayed behind other screen content.  This provides awareness of position and impending write actions and allows intentional pointing to locations of the screen.  It also has the advantage of being transmitted with low bandwidth, being relatively insensitive to low frame rates, and minimizing visual interference with substantive data being displayed on the screen.

title: Less talk, more action: (Re)Organising universities in Aotearoa, New Zealand

authors: Simpson, Aimee B.

subjects: Academia

abstract: Despite the growing size of the academic precariat in the tertiary sector, this exploited group of workers lacks a voice in either their universities or their national union. In this article we draw on our experiences of transitioning from a small activist group to a broader research collective with influence and voice, while forging networks of solidarity. Through reflecting on developing the Precarious Academic Work Survey (PAWS), we explore how action research is a viable way of structurally and politically (re)organising academic work. We argue that partnering with changemakers such as unions as co-researchers disrupts their embedded processes so that they may be (re)politicised towards pressing issues such as precarity. Further, we highlight how research can be used as a call to action and a tool to recruit powerful allies to collaborate on transforming universities into educational utopias.

abstract: Nö te tau 2001 i whakatüria ai e Ako Aotearoa (National Centre for Tertiary Teaching Excellence) tëtahi tohu hei whakanui i ngä mahi a te tangata e whakaako ana i te taumata takiura. Me whakaatu te kaiwhiwhi tohu i tana ü roa ki ngä taumata tiketike rawa i tana mahi whakaako. Tekau mä rua ngä kaiwhiwhi toa i ia tau, kätahi ka whiriwhirihia ai e tëtahi kömiti kaiwhakawä kia kotahi te tangata e whiwhi nei i te Tohu Tiketike o te Pirimia. Mö ngä tau e whä kua hipa ake nei i riro i ngä kaiako Mäori te tohu tiketike nei. Ko te aronga o tënei tuhinga he whakaatu i ngä ähuatanga o ënei kaiako kia märama pai atu ai te whakaaro tiketike o te Mäori ki tënei mea te ako.
