Okay. So um I thought um I would also include the definition of user interface um so it's the aspects of a of of a computer system or programme which can be seen uh by the user um and and which  uh the mechanisms that the user uses to control its operation and input data. So this would p includes things like shape and size and buttons and um voice recognition as well , and colour , and so on.
Mm-hmm.
Um um the method I  employed this time was  a again having a look to related products and mainly on the internet and then  um  analyse them uh from the point of view of user fen friendliness and  also um  whether their appearance was was pleasant. Um  and then um  this uh this um  this can help us to decide which features we want to incorporate in our product.
Mm-hmm.
