Project Goal

To ideate and design a digital interface incorporated through a special pair of contact lenses, D-Lens. After purchasing and registering the product, the user can open the interface under their unique identity, change settings to their preferences, and try out different functionalities. The main purpose of D-Lens is environmental interaction through digitized drawing and design.

Our lens operates with an embedded microchip within the lens. The lenses are designed with maximum safety so that it provides insulation if the microprocessor ever overheats. We highly suggest users to take off these lenses before a prolonged period (do not exceed 8 hours) for eye protection. We believe that in the near-future, there will soon be better technology to invent 100% durable lens that does not affect human eyesight. For now, for the safety concern, our lens are biodegradable so that they will dissolve into human tears and be washed away if any users exceed the wearable time.

On the technical side, D-Lens allows communication through data, wi-fi and even bluetooth if set up correctly. Everything on the client side is processed by the microchip within the lens that sends information off to the central server. Drawings that are in public mode will mark the coordinates on a city-scale map, and the users with D-Lens nearby will receive the signal and display the drawings accordingly.


When putting on contacts, the user will see the main menu button on the top right or left corner, depending on the user's hand preference. There will be a set of four buttons (in a counter-clockwise view): Drawing mode, Note mode, Contact, and Settings. The section below will specify the function of each button in details.

D-Lens’ home page


Drawing Mode

User select Paint function in Drawing Mode


This function allows the user to choose a color for his or her paint brush. The color menu bar pops out where it saves the user's customized color choices (or primary colors by default). By clicking on the plus button on the right side, user can add additional color to the bar. If the choices of color exceeds five buttons, then the user can swipe to access other colors.

Paint Brush

User can change the brush settings or choose a new brush tip. Additional brush tips can be created through painting and saved (like in Photoshop). User can also download/purchase brush tips online or through in-app store.

User select Material Function in Drawing Mode


This is our unique function where user can tap on a specific object in real world and pick up its materiality for additional drawings. User can then tap on any other objects to change their color or material. This function is a cheap way for designers and artists to see a digital prototype before actually making the physical prototype of their artworks or products.


This button leads users back to the main menu.



Note Mode

User select Add Function in Note Mode to add a new note.


Add a note. This will lead to another layer where the user can choose typing with keyboard or handwrite.

Old Notes

This button allows you to go through your old notes, review, edit and delete them.

User select Note Mode in D-Lens' home page


This button leads user back to the main menu.



User select Tutorial Function in Contact Mode to learn how to use D-Lens

User select Sign-language Function in Contact Mode


This tab contains the basic tutorials for major functionalities. For example, if the user wants to know how to manipulate gestural control, it can use voice recognition and ask D-Lens to directly search for "gestural control". Under that, the user will be able to see image and textual instructions for taking a picture.


If the user has a question that is not addressed by the Tutorials button, then he or she can directly have a conversation with an assistant through call.


For the hearing impaired, we provide a special tab for them to have a direct face-to-face call with a translator who knows  sign-language.


This button leads user back to the main menu.



User select Cloud function in Settings


User can change the interface language.


User can turn on their wifi or data through this tab.


This is an essential function where user can choose whether or not to automatically save their images onto cloud.

App Shop

User can purchase additional apps, skins and related products through the online D-Lens store.


In addition to drawing and note taking, the D-Lens also allows collaboration among artists; this is especially useful when groups cannot find time to meet up, and in general it is fun for quick collaborative art among artists and friends. Public spaces can also be set up for collaborative art events where D-Lens users can draw together and share ideas. D-Lens glasses are available at these events for those who do not have D-Lens but wish to participate or check out the art. Artwork from these events can be saved by the venues for people to see in the future. Otherwise, they are temporary and will be erased to keep space available for new artwork.

Video Showcase

Our video showcases several functions in which the D-Lens users can create art in public spaces (with public and privacy settings) and save drawings, change the colors of objects in a space, browse in home page and enter into a mode, and take notes.

Example User Cases

User case 1

An art student would find the D-Lens convenient for taking notes, collaborating on projects, and generally creating art. Let's say Nathan is an art student at UC San Diego.

On weekdays when Nathan has class, he can take notes either by handwriting or typing them using the D-Lens. While this helps conserve paper consumption in lecture-based classes, the D-Lens is also useful in courses where writing is not convenient. For example, in lab sections for a film class, Nathan is typically filming outdoors. He has a camera propped up on the tripod, and one hand is holding a microphone to record sound. If he wants to take notes, he can simply select the notes function and start writing with the other hand without putting down the microphone. Similarly, he can retrieve notes, such as storyboards and/or ideas for specific shots, that he took beforehand to refer to with ease during shoots.

Outside of class and on weekends, Nathan can use the D-Lens to make notes and sketch ideas when he finds inspiration, or to just draw for fun. Like in the filming example, by utilizing the D-Lens, Nathan saves time by not having to take out his sketchbook. If he forgets his sketchbook, he can use the D-Lens to draw. Then his art can be saved for working on more

later via D-Lens, other computer-based art programs, or for printing out. Furthermore he can use the D-Lens to select any material to draw with, which helps save money for art materials and enables more room for experimentation.

User case 2

The D-Lens makes designing much easier for the interior designer. 

For example, Elena is an interior designer working on a house for a client. She can preview room colors and pick out furniture by using the color palettes and furniture libraries stored on her D-Lens. There would be no need for her to draft her designs on her computer and she can walk in and see how the space changes according to her design. Additionally she can jot down room dimensions and measurements for accurate planning; these can be done either with the draw function where it will show up in each room she walks into, or in her notes. If her client uses D-Lens, or if she has a pair of D-Lens glasses, Elena can give her client a tour around the house with her design ideas implemented digitally and collaborate with the client. Otherwise Elena can still share her designs through pictures via email, printed copies, etc. This saves a lot of hassle of drafting designs with the computer and gives a more realistic preview of designs before actual implementation.

Reflection and future plan

review · What's good about D-Lens

D-Lens is a product targeting artists, designers and students who need a digital tool to enhance their art experience. Functions such as drawing, bucket colors and changing materials allow users to transform their artworks from 2D to 3D space. D-Lens is completely subjected to gestural control and voice recognition where the boundary of tools is completely eliminated. Moreover, the implementation of privacy settings supports collaborative drawing and encourages teamwork.

Future · What we plan to improve

However, it is also possible that manipulation of the program can potentially cause city-wide problems and chaos. Therefore, the usage of D-Lens need to be closely monitored by both the company and the local police force to ensure safety. Otherwise, we believe that D-Lens can bring great convenience to the art-making community and spark a new form of creativity among the population.
