Interaction design is to design a complete user operation process and user interface, and at the same time ensure that the designed user operation process and user interface conform to the user's cognitive model, so as to reduce the user's troubles and negative emotions during the use process and lead to the failure of operation tasks. .
What is the value of an interaction designer?
Interaction designer is to undertake the role of upstream (product manager) and downstream (visual designer).
The value of interaction designers comes from two aspects:
One is the value in the team's workflow;
Another aspect is to improve the user experience of the product.
Value in Team Workflow
The needs of product managers come from the iteration of business, user demands and their own functions. The product manager obtains the product requirements by transforming the business objectives into product objectives and following the development rhythm. After the product manager completes the product requirements, he will start the requirements review.
As to whether the demand is reasonable, the user researcher can cooperate with the product manager to conduct user demand research to prove the rationality of the product demand.
The interaction designer should participate in the requirement review. After the requirement review is passed, the interaction designer should start the interaction design under the premise of being familiar with the business, and convert the product requirements into the user operation process, interface and corresponding interaction annotation b2b data instructions. The output of the teacher is the interactive output document.
The visual designer should participate in the interactive review. After the interactive review is completed, the visual designer will make a corresponding visual design draft. After the visual designer completes, the interaction designer must review the visual draft to ensure that there is no problem with the interaction logic and visual interface, and then conduct a visual review. After the visual review, the corresponding visual draft is given to the corresponding developer.
Development engineers can start functional development after the requirement review. After the development is completed, testers conduct functional testing and interactive visual walkthroughs.
The above is a more common workflow. Of course, in the ued team, the interaction design draft and the visual design draft are first reviewed internally, and then reviewed with the product manager and development.
Because the product manager is responsible for a wide range of areas, and requires energy in all aspects, the product manager also spends part of his time in the process of drawing prototypes. In this process, it is inevitable that the process is not detailed and comprehensive, and the delicacy of the design is not controlled enough.
Interaction designers exist to help product managers transform product requirements into interactive process interfaces (prototypes). Interaction designers undertake the work of drawing prototypes, which greatly reduces the workload of product managers.
With the interaction designer, the visual designer no longer needs to repeatedly modify the draft, because the interaction draft and review have already determined the interface and various logical state interfaces, and the visual designer can focus on the beautiful vision of the interface. superior.
Improve user experience
1. Design with scenario-based thinking
Interaction designers are generally better at figuring out user behavior and psychological characteristics, and designing user behavior according to scenarios. The scene-based thinking design is in line with the user's behavioral characteristics, which ensures that the user is barrier-free during use.
Taking the mobile phone mailbox as an example, the main scenarios involved include: replying, forwarding, and marking the email status anytime and anywhere through the mobile phone; sending some simple emails; email search.
(1) Xiao Ming logs in the company mailbox in the mobile mailbox app. Since many things at work are done through mailboxes, when Xiao Ming is not at the computer, he occasionally checks the emails received by his mobile phone mailbox.
When Xiao Ming sees an important email, he will enter to view the details. The email needs to be forwarded to other colleagues, and will be forwarded. After entering the forwarder, click Send.
If this email will continue to be viewed next time, it will be marked. When you need to reply to this email, you will click the reply operation to select the sender or everyone.
(2) There are some pictures and videos on Xiaoming's mobile phone, which need to be sent to the computer for viewing and use. Because the video quality will be compressed when sending videos through WeChat, and QQ is not used very much, so he will use the mailbox to send short videos and original pictures.
