In essence, they are soap bubbles that can have images projected onto them or - when they are burst - release a scent...
The research at Bristol University is led by Professor Sriram Subramanian from the Department of Computer Science.
Possible applications? Possibly advertising and certain forms of education, such as museum exhibits, suggests the university.
“There are many areas in which bubble-based technology like SensaBubble could be applied," said Professor Sriram Subramanian, "such as a SensaBubble clock that releases the number of scented bubbles corresponding to the hour or SensaBubble Maths, an educational game for children, which incorporates smell as feedback on their success."
Take a look below:
A research paper will be presented at ACM CHI 2014, a conference on human-computer interfaces.
