1. A vision-assist system comprising:

  • one or more processors;

    a memory module communicatively coupled to the one or more processors;

    an environmental sensing device communicatively coupled to the one or more processors and operable to generate information regarding an environment;

    a feedback device communicatively coupled to the one or more processors and operable to generate feedback at least partially based on the generated environmental information of the environmental sensing device; and

    machine readable instructions stored in the memory module that cause the vision-assist system to perform at least the following when executed by the one or more processors;

    record a first metric corresponding to a level of reliance by a user on the feedback device at a first time, wherein the level of reliance is based at least in part on a measurable dependence on the generated feedback, and wherein the level of reliance is at least partially based on at least one of;

    a Braille assist feature associated with the environmental sensing device and the memory module,an object identification assist feature associated with the environmental sensing device and the memory module to assist the user in identifying an object, anda facial recognition assist feature to assist the user in facial recognition;

    record a second metric corresponding to the level of reliance by the user on the feedback device at a second time, wherein the second time occurs after the first time; and

    record an awarded amount of reliance points when the second metric is less than the first metric, indicative of a decrease on a reliance by the user on the vision-assist system, wherein the awarded amount of reliance points corresponds to a percentage by which the second metric decreases compared to the first metric.
