Proposal 1 - Wardrobe for the visually impaired

Problem: People with some kinds of sight disabilities can have a harder time than most picking appropriate outfits. Much of that is currently mitigated using outside assistance and memorization, for example associating textures/shapes/positions to colors and patterns. But this raises problems, some of which will be the focus of the solution proposed:

• No reliable way to autonomously confirm the memory (e.g. check the color)
• Picking out a specific desired pieces can be a slow and bothersome process
• No trustworthy and time effective way of asserting a specific piece is not present

Proposed Solution: Designing, building and developing a device to be installed in the user’s wardrobe and hangers, with assistive software and hardware to facilitate the picking and managing of clothes articles.

The main body of the solution would be a “pointer” to find the requested piece in the wardrobe and easily lead the user to it. The request is made by voice commands, taken and processed by the embedded system, which will prompt the moving head to start scanning the tags present on the hangers with the clothes, signaling to the user when and where it was found, or when it fails to do so.

Other functionalities of the central module would include:

• a sensor to ascetrain and declare the color of a given piece presented to it
• A tag reader that reads aloud the identifiers associated to any given tag (to facilitate organizing clothes back into the wardrobe)
• wireless communication with a mobile app and/or server to enable basic managing capabilities (adding/removing/editing tags)

Additional supplementary ideas:

• Allow for the creation of “outfit presets” which will begin sequentially pointing to sets of clothes making up the outfit
• Include clothes suggestions based on current climate conditions or seasonal colors

Yellow: embedded system with control center and user interface

Green: identification tags of each piece, fixed on hangers to avoid damage to clothes themselves

Blue: moving head that reads the tag and “points” to the desired piece

Red: support bar for the head (separetaed from the bar for hangers)

Proposal 2

Blockchain-Based Notary Kiosk

Problem:

Forged documentation and identity fraud remain persistent challenges. Traditional notary offices rely on authentication methods like manual stamps and seals, which can be easily tampered with or replicated on fraudulent documents. Moreover, the current system is centralized, depending on individual institutions for verification. This creates bottlenecks, security vulnerabilities, and delays from manual cross-checking. The reliance on physical records and time-consuming processes increases fraud risks and creates inefficiencies, forcing clients to wait long periods for simple tasks like obtaining certified copies.

Proposed Solution:

A self-service kiosk that automates notary tasks requiring no human intervention (e.g., witness presence), combined with blockchain technology for secure, transparent, and efficient document validation. The kiosk’s core functions include:

1. Copy Authentication (via scanning and blockchain-linked QR code).
2. Certificate Issuance (birth, death, property) integrated with government databases.
3. Digital Signature Validation via biometrics or digital comparison.
4. Automated Payments (Pix, credit/debit card, bank slip).
