London (CNN Business) Apple will introduce disability-themed emojis in a move designed to "bring even more diversity to the keyboard."

The emojis , which were unveiled to coincide with World Emoji Day, will include a guide dog, an ear with a hearing aid, wheelchairs, a prosthetic arm and a prosthetic leg. They will be available to use later this year.

"Celebrating diversity in all its many forms is integral to Apple's values and these new options help fill a significant gap in the emoji keyboard," an Apple spokesperson said in a statement.

Apple submitted the proposal for more disability-inclusive emojis to the Unicode Consortium last year.

The tech giant submitted a proposal for more emojis that were inclusive of disability in a proposal sent to the Unicode Consortium — the nonprofit organization that sets the global standard for emojis — in March 2018.

"Currently, emoji provide a wide range of options, but may not represent the experiences of those with disabilities," Apple wrote at the time. "Diversifying the options available helps fill a significant gap and provides a more inclusive experience for all."
