#MULTITOUCH TABLE SOFTWARE#

On the software end, both low level finger tracking or hand jester and high level software development will be in the Open-Source domain as a part of the Multi-touch device technology. On the hardware end, various materials (camera, projection screen, etc.) will be needed to construct the table. Through the developmental process, I will be exploring both the hardware and software side of Multi-touch computing. Within the design, a framework will be programmed that will make use of the table’s Multi-Input (Touch) ability. A Natural User Interface will act as the visual feedback where users can directly manipulate what is projected on screen. A display table designed for Multi-touch interaction will be the point of my blog collaboration. My mission plan is to design a Multi-touch environment that allows an individual to work in a computer aid environment. The camera is connected to a computer and a tracking application uses the camera image to track and create touch coordinates.The projector is connected to a computer in order to display the software on the touch surface.

A camera can be modified to only see the infrared spectrum of light from objects/fingers on the touch surface.The System has a projector for a visual feedback system where an image from a projector or LCD is projected or placed below the touch surface.Infrared light is used to distinguish between a visual image on the touch surface and the objects/fingers being tracked.An infrared camera is pointed at the touch surface and detects when fingers/objects touch the surface.In comparison, at NMMNHS 80% of the visitor groups showed some form of social interaction. At the Indian Pueblo Cultural Center, where the table primarily controls access to short videos, 25% of the visitor groups had some form of social interaction. Social interaction cues for visitor groups varied widely by site. We measured social interaction at each of the sites using a variety of behavior and verbal indicator, such as ‘makes positive statements about surface technology’ or ‘emotionally reacts to exhibit’. While we’ve observed longer stay times at other multitouch tables, those tables tend to have more content or directed interactives than the collections-based content currently on the Open Exhibits tables. The stay time in each of the galleries was longer for the table than any other object in the galleries, averaging about 2 minutes at each site. For instance, in the New Mexico Museum of Natural History and Science, over 86% of the visitors spent time with the Stegomastodon jaw, and roughly 63% used the multitouch table. In each of the galleries we studied, the multitouch table was not the most ‘popular’ object in the gallery, that was always an element of the collection. One of the questions within our research was whether having a table in the galleries impacts the amount of attention and the amount of time spent on other elements. These rates are similar to other first-use rates at small-to-medium sized museums in small to medium population areas. During interviews from the late fall of 2012 in Albuquerque, most visitors (73-82%) had not seen a multitouch table previously. How often do visitors use multitouch tables? While Ideum and others have been producing multitouch tables since 2008-2009, data collection for Open Exhibits research suggests that the tables are still novel to most museum visitors.
