Indexing Annotations Type Captcha
Following points suggested by community members, I have drafted few points which are mentioned below :

Modifying "annotations based questions", we can modify annotations based question to have ReCaptcha like solution, which would help us index images for Mediawiki site. An example for the question is shown here:



Now the only provided index for the images in the Wiki commons database is "Cat", while selecting the correct options for the image, correct answer ( Options ) to the question is: "Cat" and "Humans"



Utilizing Indexed System
These indexed photos can be provided as question to Visually Impaired but not completely blind user's. For Example: Image as options can be provided to Visually Impaired user's without manipulating them with any kind effect.



Advantage
These logical question are difficult for bots to solve since index's developed as an overtime Captcha Run are stored in Mediawiki Sites own database.

For blind and visually impaired users
Rather than developing a completely new type of captcha the approach could be to improve the interface of pre-existing Audio Captcha.The approaches to improve the captcha could be: 1) Assigning a key to make an audio playback. This audio playback for the same sound can be made for 3 times. After which the voice and the number spoken will change. 2) Assigning a key to make delay in the captcha voice for small duration of time. 3) Assigning a key to reload a particular number in the captcha, rather than reloading the whole captcha again a key could be assigned to reload a specific portion/number of the captcha. More information about the improvement of the captcha could be found here.

Selecting/Customizing categories for images to be displayed
An additional point to mention about customizing categories, there can be an array of categories similar to array of character in Questy Captcha, these categories can be customized by Wiki owner's. The use Categories will be to fetch images belonging to that category from wikidata. For example:let us define an array of categories as array('Human','Animals','Ocean','Mountain').Now the Captcha will fetch images for questions from these given categories only.

Advantage

 * It would provide Wiki administrator with opportunity to customize the image,hence providing effective localization for the Captcha
 * Enhances the Captcha with an robust feature of Questy Captcha ,alongwith adding more possible images for a given Captcha.

How to make these categories Unrelated
In order to make categories unrelated we can make super-set of the categories for example:-> there could be categories of artist,astronauts can be categorized under the Super Category of humans, similarly collection of an array can be made comprising of unrelated categories such as “people”, “animals”, “machines" etc...,moreover this array of unrelated categories can be modified by administrators of Wiki's to add more categories according to his need.

Captcha for Mobile Device
The Captcha for the mobile devices will be shown over Lightbox effect produced with the help of JQuery.

For "annotation type captcha" the design over lightbox would be like:



if the users clicks on the correct option next image to be verified will be shown as shown below:





If the user clicks on an wrong option all the image options of the captcha will be reloaded, and different images with options will be shown.

Moreover for "Odd one out" type question the layout of the question over the lightbox will be as shown:



Similar to annotation type captcha, if the user clicks on an wrong option all the image options of the captcha will be reloaded.
