CVI Complexity Sequences Kit (1-08156-00)

The CVI Complexity Sequence Kit (1-08156-00) is designed for people with low vision and consists of image sequences on cards for use by students with CVI who have success with 2-dimensional materials. APH’s CVI Complexity Sequences Kit includes cards that present sequences of images designed to refine the ability to identify a target in the presence of increasing amounts of background information. These cards may be used individually or as a sequence and should be presented against a black or plain, light-absorbing background. The CVI Complexity Sequence Kit can be used by parents of children with Cortical Visual Impairment (CVI), teachers of visually impaired students (TVIs), or individuals. Users who have purchased the CVI Complexity Sequences Kit can now utilize all 80 of the images in digital format in their web browser. To access go to: https://cvi.aphtech.org/

For a user’s convenience and teaching use, the images are accessible using a browser on a desktop computer, laptop, tablet computer, or smartphone. Each image appears individually on a white background in the browser window. On-screen buttons allow users to navigate from image to image and from image set to image set, both forward and backward.

Note: it is not recommended that these images are used with students unless the protocols described in the Guidebook that accompanies the CVI Complexity Sequences Kit are followed. The kit is designed to assist individuals with CVI improve their ability to:

• Recognize or identify simple, colored, 2-dimensional images presented in isolation
• Recognize or identify images presented with increasing numbers of background elements
• Identify a key image based on the salient features of that image
• Recognize or identify images presented in a variety of locations and with increasing numbers of background elements
