Reviewing Data and findings
Based on the raw data [1] provided, it indicates that from Visual Captions, an open-source Chrome plug-in, Keywords will be extracted and visualized based on the dialogue and contextual semantics between users. These would then be converted from text into pictures, emoticons, videos animated pictures, 3D models and wireframes.
Mental Model Description based on the given design challenge.
Norman, A. Donald emphasised, "People form mental models through experience, training, and instruction. The mental model of a device is formed largely by interpreting its perceived actions and its visible structure" [2, p.17].
The figure below is a possible user mental model based on the design challenge:

In preparation for travel, users would prepare documents. During the journey, they would prepare a translation application, go shopping and explore the city. Afterwards, people would like to manage logistics like tax refunds, share photos with family and friends, and plan future adventures.

Sketching about how the application works
Sketching is the third step of the Double Dimond model, serving as a pivotal phase in testing and exploring various solutions.[3]

Designers should consider the following three design principles:
First, “Support Internal Locus of Control” [4]. Designers should give users the freedom to control private photo albums. To protect privacy, users have the right to choose to turn off the use permissions of specific photo albums.
Second, “Contrast and uniformity” [5, p.139]. “A design without contrast is seen as a gray…” Most of the app usage scenarios are outdoors, so the color contrast and font size contrast should be obvious.
Third, according to Norman, A. Donald [2, p. xii], the concept of "Feedback" is crucial in design principles. When users use real-life navigation, if they take the wrong path, they must promptly remind and provide feedback on the latest status.
