Before I started hypothesis testing using the first prototype. I did a diary study to find out what situations people usually feel unsafe when they are alone. So I asked 20–30s 6 people (3 Male, 3 Female) to write down memos whenever they feel unsafe when alone outside for a week.
Below is the result note.

To expand my thesis idea and get some unexpected insights I expand research into unexpected areas which are related to my thesis problem but are kind of different. My classmate Tien-Wei recommended research about the things visitors should not do in certain countries. And I think it is very interesting and helpful so I did some researches about it. Below are some findings.

Before I started further researches, I mapped my assumptions about solo travel safety. After I created assumptions mapping, I got some feedback from my classmates (Tien-Wei & Yuxuan). And then I organized my assumptions in the table. Lastly, I created a priority matrix to find out the assumptions having higher priority to test.

Here are some assumptions I have for my thesis idea.
- There are a lot of people who gave up traveling alone because of safety issues.
- There will be already many services for safe travel. Some must be helpful but some are not helpful.
- People’s feelings about safety can differ depending on certain cities/countries.
- People think current safety services/systems for traveling alone are not enough to feel safe.
- Travel alone can be more dangerous for women, children, seniors, and people with disabilities.
