Actually, an emoji is defined as "any of various small images, symbols, or icons used in text fields in electronic communication (as in text messages, e-mail, and social media) to express the emotional attitude of the writer, convey information succinctly, communicate a message playfully without using words, etc" (merriam webster)
So I think the icons seen in the graphic would qualify as emoji.
