《Human centered Design》
第一个课程偏概念导论,重新梳理了一下新接触到的方法论,方便自己理解。
课程结构:挖掘需求→原型设计→评估设计
Process of Prototyping01.发现需求&定义目标
观察和采访:避免主观倾向性,不然容易产生伪需求
用户肖像:帮助将用户群细分结构化,从不同维度来看需求
02.如何快速原型化?
考量:保真度&时间成本
高保真的原型投入太大,用户批评起来有压力
低保真的原型反而容易获得更多用户反馈
Form and Feedback Co-evolve1.storyboarding:沟通场景和任务
2.Paper Prototyping:沟通草稿界面
3.Wizard of OZ:模拟交互(通过人的操作来替代机器的行为;一个人模拟机器,一个人读剧本输入指令,一个人模拟用户输出行为/反应,快速发现问题),在youtube上搜的一个案例:https://www.youtube.com/watch?v=d8SEFSpBYzY
4.Digital Mockup:沟通精细界面(上Axure或Principle了)
5.Parallel Design:多个并行方案,多个版本更有利于对比和决策,产出更好的结果
my assignment here:
Problem : A freshman may not notice what traffic problem they would face, sometimes they notice it, but they have to search it online which is hard with high cost .
Idea 1: Map app diagnose that,and integrate all the solutions into navigation flow. Fold all the informations under a module(Advantage:we would not miss any thing important because we always use a Map to navigate before getting around)
Idea 2: Instead of integrate solutions into navigation flow. Fold them separately , display in categories. (Advantage:Users can learn all the solutions in advance clearly)
Idea 3: Add a compare system for global travelers. It helps users to finder better choice and also helps backend to diagnose what the travelers may need to know better.
03 评估设计
不同的测试方式解决不同的问题,适用于开发中的不同阶段。
Evaluating design启发式评估 Heuristic evaluating:
3-5人独立评估-各自发现的问题-汇总讨论
来自Jacob Nilsen的几条原则,很实用的框架但不限于此:https://www.nngroup.com/articles/ten-usability-heuristics/
内容-易识别
Match between system and the real world
Consistency and standards(一致性)
Aesthetic and minimalist design
行动-流畅
User control and freedom
Recognition rather than recall(比如default)
Flexibility and efficiency of use(推荐系统、预测行动、开放式选项、关联内容)
响应/反馈-不缺失
Error prevention(报错)
Visibility of system status(如:告知变化、下一步、时间、已完成,等状态)
Help and documentation
Help users recognize, diagnose, and recover from errors(如,填表格后报错并提示如何正确填写;搜索引擎直接替换输入错误)
