Research Used in the Development of the MagnaFlyer Training Protocol

 

The Purpose of MagnaFlyer


The purpose of the MagnaFLyer Training Program for Low Vision Rehabilitation is simply to create a more time-efficient means of delivering training for low vision rehabilitation. The notion grew out of the practical experience of low vision professionals who sought a more productive way to provide care. In this regard MagnaFlyer should be considered in the same category as other assistive or instructional technology such as magnification, smart white boards, CCTV or software applications. It is not intended to represent new science but rather a means of adding efficiencies to the practicum already in place.

 

The conclusions regarding it's efficiency are related to the speed with which a successful client outcome can be achieved when compared to previous non-computer based methods of delivering equivalent practice and exercise materials.

 

MagnaFlyer is a computer application resulting from a multidisciplinary design process conducted by a team of low vision specialists, technologists, software engineers, graphic artists and writers.

 

This multi-disciplinary approach was necessary for creating an enhanced means of specialized training delivery. Much of the resultant product was based on research from a variety of sources.

 

Included in the considerations for the design were:
• The best practices currently used in implementation of training for steady eye and eccentric viewing techniques

• Practical input from low vision specialists and practitioners who conduct training

• Data from third party peer reviewed clinical research

• Validation from field testing

 



Supporting Research Materials Relevant to the Methods and Protocol used in the MagnaFlyer Training Program:

 

Note: Rapid Serial Visual Presentation (RSVP) is the general term for the type of sequential display technology used in the MagnaFlyer display. The MagnaFlyer software display engine is a patented variant which uniquely modulates the rendering of the text display with a cadence based on the content file. This allows for variable duration of word display based on a number of parameters contained within it’s algorithm.

 

1. Field Test Report of the MagnaFlyer Computer Based Training Program for Steady-Eye Technique:

This field test was conducted by Ensight Skills Centers for Low Vision Rehabilitation. The process, description and outcome of the use of the MagnaFlyer Program for training steady eye and eccentric viewing techniques within the rehabilitation setting when compared to previous paper-based methods.

2. Reading of Dynamically Displayed Text by Low Vision Observers

This study indicates that readers with CFL are able to read 50% faster with RSVP than with statically displayed text.

4. nihms-172932 Enhancing Visual Performance for People with Central Vision Loss

This study was conducted using RSVP for reading display as the preferred modality for measurement of reading speed in the periphery over page reading. [LINK]

 

5. Effective rehabilitation of reading by training in the technique of eccentric viewing: evaluation of a 4-year programme of service delivery

Conclusion: Eccentric viewing training is successful in improving the reading ability of individuals with a central scotoma. This paper shows evidence of the success of training provided by the voluntary sector and funded by adult literacy funding. The results are comparable with those reported in the literature.

6. Training eccentric fixation for reading: The implementation of a community based service – a pilot study.

A study conducted in the UK demonstrating the practical benefits of eccentric viewing (Steady-Eye) technique for activities of daily living.
Visibility (a UK rehablitation organization) has recently been involved in setting up and developing an eccentric reading programme for people with central visual loss (New View Project). This report is an evaluation of the first group of 21 people who participated in the project. The results show that the eccentric reading technique can make a considerable impact on functioning reading skills and in turn increase confidence and independence. [Link to PDF]

 

7. Improving Reading Speed for People with Central Vision Loss through Perceptual Learning

This study researches the effects of training eccentric viewing and other techniques using RSVP.

8. Low-Vision Patients with Age-Related Maculopathy Read RSVP Faster when Word Duration Varies According to Word Length

This study refers to the variable duration of word display in RSVP. This is a component of the method incorporated in the patented text display used by the MagnaFlyer Program. [LINK]

 

9. Reading Without Saccadic Eye Movements:

Seminal study conducted at Johns Hopkins University showing the effect of RSVP display on reading speed and comprehension. It was upon this research that development of MagnaFlyer proceded.[LINK]

    MagnaFlyer was developed was to serve two equally important purposes:
  • Allow the practitioner to more efficiently use their time in session to focus on the client
  • Give the client a way to achieve more positive results per session encouraging their confidence and reinforcing their own sense of progress.
