LifeScience Technologies Cortical Visual Impairment System is an effective tool for executing protocols designed to help strengthen the vision of those with Cortical Visual Impairment.
Cortical Visual Impairment is the term used for a brain that misinterprets signals from otherwise healthy eyes. In 2013, Christine Roman-Lantzy, PhD, developed a protocol for improving the vision of kids with CVI that has proven extremely effective in helping them to recover their vision. LifeScience Technologies has augmented our base care system with components that allow a teacher to build lesson plans according to this developed protocol. Our CVI system also has components available for monitoring, managing and improving the treatment program, based on a qualified educator's use of our system's features.
The Lesson Planner allows a CVI educator to create and assign lesson plans that follow the CVI protocol. The lesson plan defines the following:
The Training Session Manager is capable of interpreting instructions in the lesson plan, for example: "display a black background and move a red box around the background for a count of 'X' seconds" - and displaying elements as specified. The Training Session Manager also offers the following capabilities:
The Training Session Monitor allows an instructor to join in on a training session in order to monitor that session and has the following capabilities:
The system uses audible sounds to provide behavioural feedback to students. If a student looks at the images displayed on the iDevice, a positive reinforcement sound is played. If a student were to look away, a negative reinforcement sound can be played. Sounds are important methods of feedback for CVI kids. As such, our system allows for the sounds to be tailored so that what sounds are played match the desires of the student.

Our CVI application displays training sessions to the student using an iPad. The orchestration of the training session is managed by our web server and online services.
Defining lesson plans is as easy as selecting web pages that capture what the educator wants the plan to include. There are tools for managing plans and assigning plans to students as well as tools that allow the educator to see how often and how well a particular plan is working.
When a training session is progressing, the iPad sends events to the website via our web services. The events are basic units of information about: buttons being pressed, screens being touched and sessions starting and stopping - as well as a new feature on the website that analyzes the results of a training session. It takes all of the basic event information from the iPad and generates interesting facts about what has occurred within a training session. For example, the expert:
All of these expertly-determined facts can then be graphed and analyzed by the educator, in whole or in part, across all training sessions. For example, it is possible to graph the time spent, on average, on training sessions combined with the number of times a sprite is touched, showing ways of measuring improvement in visual acuity as well as allowing a teacher to tailor future lesson plans to better match the needs of the student.
In addition to analyzing favorite and least favorite lessons, the CVI system has the ability to use information from the training sessions to automatically generate new training sessions that are best for the student. As an example, the system can detect highly touched areas of the iPad and where sprites are commonly touched. Using this information, the system can automatically generate new lesson plans that focus the attention specifically on these areas as well as specifically AWAY from these areas to improve acuity. The system can use facts about the lengths of time spent on average by the user on training sessions to tailor the length of time a typical training session should take place.
There are a number of ways that these new features integrate and make use of our base system to provide the complete solution for managing CVI student populations.
