iPhone Duo, a New Usage Experience Beginning with a Foldable Form
1. Assign different roles to the two screens
The form factor of iPhone Duo connects the screen you carry with the space you use when unfolded.
- How it is used when folded and unfolded
- The external screen is more than 90% of the display area of the iPhone 18 Pro, and the internal screen provides a 19.3 cm display.
- From a design perspective, the point to examine is what tasks begin and continue on each screen.
- A surface that lets you focus on content
- The internal screen uses a Nano-texture finish that reduces reflections and an under-display FaceTime camera.
- This can be read as a design that aims to reduce elements that obscure content on the expanded screen.
2. The folding angle changes the layout
The direction of the screen and the posture of the device determine together where information is viewed and where manual操作 occurs.
- Space allocation across landscape and portrait screens
- In Split View, you can place two apps side by side and drag photos into Mail.
- A configuration that shows reference materials and a work area at the same time changes the movement of switching between apps into movement within the screen.
- Usage postures expanded through sitting and standing
- When folded halfway and set down, the device itself acts as a stand, and in a seated state you can access the controls at the bottom.
- In foldable UI, the screen size, as well as the height of the gaze and the range that the hand can reach, become design targets.
3. The second screen creates participation from others
The external display becomes a point of contact that also conveys information to the person being photographed.
- Real-time feedback from Duo Preview
- The subject can check their own framing on the external screen.
- By letting the other person directly see information that the photographer would otherwise convey verbally, there is room to coordinate the photo together.
- Guiding attention with Eye Sight
- Animation on the external screen guides a child's gaze toward the lens.
- This is an example of varying the form of feedback according to the person looking at the screen and the desired action.
4. Colors and materials support the form
The two colors, Night Sky and Star White, along with the titanium frame and hinge cover, make up the product's exterior.
- Expression through restrained color and structure
- In the official images, the limited color palette draws attention to the outline of the frame and the folded form.
- When looking at CMF, it is worth examining not only color but also the relationship between the surfaces revealed in the open and closed states.
- Connecting the finish to the usage experience
- The Nano-texture on the internal screen serves the functional role of reducing reflections.
- When evaluating materials and finishes, distinguishing the impression of the appearance from actual visibility, touch, and durability allows the design intent to be read more accurately.
