What is Abaris?Abaris is a fully functioning prototype capture and access application to support therapists who perform Discrete Trial Training therapy, a current best practice intervention for children with autism.
Formative work on Discrete Trial TrainingWe have studied extensively the domain of discrete trial training through participant observation and interviews.
Discrete Trial Training has the following characteristics:
The high amount of manual data collection and recording can lead to inaccuracies in the data, which can affect a team's analysis, and draws the attention of the therapist away from the child.
The Abaris project attempts to address some of these deficiencies in order to increase the accuracy of data collection and reduce the amount of time the therapist spends doing manual calculations. Additionally, since Discrete Trial Training is almost always carried out by a team of therapists for one particular child, Abaris attempts to facilitate the communication among teams to ensure that each member is performing the therapy consistently.
Example of some of the paper forms used by therapists in DTT. The left shows the data collection sheet with manual calculations, and the right shows the hand-made graphs made by therapists to show trends in the child's development.
The Abaris SystemWe have developed a prototype using an Anoto digital pen and Nexidia voice indexing technology that allows for easy indexing of trials into a video session. The paper based form is very familiar to the paper ones the therapists previously used. The capture side of the interface allows for easier capture and less paperwork on a session by session basis. Abaris then provides an access interface for therapists and lead therapists to go back and review how the child is doing, look for inaccuracies, and easily show problem areas to other therapists for evaluation.
The above shows a therapist using a digital pen and voice recognition during a therapy session to index into a video of the session.
Abaris capture interface. The left images shows the Anoto digital pen and a printed form. The right image shows the simple computer program used by the therapist to sync their information with the database and access side.
Abaris access interface, data view mode. Therapists can view graphs of the child's progress, and use the mouse on various data points to get more information about a particular session.
Abaris access interface, session viewer mode. If the therapist wants more information on a session, he or she can bring up the video and data sheet for a particular session or compare multiple sessons. A time line across the bottom shows the different trials throughout the session with the timestamp guesses made by voice recognition and the digital pen.
DeploymentWe have deployed Abaris in a pilot study for four months with one particular therapy team in one child's home.
Abaris was used in:
We conducted an in-depth analysis of the collaborative aspects of Abaris and found an increased reliance on more objective measures during meetings, such as videos and data sheets, and also saw a significant increase in the level of collaboration amongst caregivers.
What is our future direction?
