Plz answer a and b both are combined questionHere are two types of virtual assistants. First there are 'live' computational models of the face and brain as in (click on the link below and view the video): https://vimeo.com/128835008 Second there are voice-only assistants in Google Assistant, Google Now, Siri, Alexa, and Cortana. 1. Describe the benefits and disadvantages of each type (live' computational and voice-only) with respect to Nielsen's five quality components of usability 1. [10 points] 2. What are benefits and disadvantages of each type when making an HCI for speakers of different languages using the same HCI at the same time? [10 points]
Explanation / Answer
The five components of usability are learnability efficiency memorability errors and satisfaction.
1. Learnability: It is easier to interact with a live computational model of an assistant than a voice only assistant. So the learnability advantage clearly goes to the live computation model of face and brain.
2. Efficiency: The users can complete tasks faster talking to a particular live assistant than a virtual assitant after the first learning phase. So, a live computational model of the face and the brain seems better at efficiency than a voice only virtual assistant.
3. Memorability: This refers to how easy it is for the user to remember the usage instruction of the device. In case of live computational model, the user has to simply interact to it like a human being which is a lot easier when returning after a hiatus from using the assistant. So, again live compurational model of brain and face gets the advantage over voice only virtual assistants.
4. Errors: This involves tracking errors about every user. This isn't an easy task without using very powerful machine. The machine is case of voice only assitant is widespread and makes use of heavy distributed systems. So, they have the advantage in this point.
5. User satisfaction: It is more satisfying to talk to a live model of face and brain than a voice only virtual assistant. Hence, the live computational model has the advantage in this case.
------------------------------------------
By using the same HCI at the same time, the knowlege of one HCI is not available to another HCI. So, this actually somewhat negates the advantage upto some degree that the strong and powerful distrubuted backend of the virtual voice only assistants provide. So, it is a bit more convenient to use a live computational model.
However a single computational model assistant may not properly adhere to the need of HCI in different langauges. This is where having a strong database of knowledge helps the virtual voice only assistants.
Also consider that in case of a computational model, the facial expressions do not properly tend to the various langauges that may be used during the HCI. A single misunderstanding caused due to messed up facial expression may actually degrade the quality of information been given to the user. A voice only virtual assistant would not face this problem.
