Overview

Modern life for families require a lot of sacrifices. To be competitive in the workplace nowadays means, besides knowledge and hard work, mobility and accessibility. Laptops, smartphones and tablets all increase productivity dramatically, but also bring the office into the home, anytime and anywhere. Nevertheless, a lot of work still require the physical presence of people, and most people might be called upon a business trip on short notice, creating havoc in the family life and plans.
However, we believe that the same technology that sometimes separate has the power to bring people together. By harnessing the power of the Internet of Things, the cloud, any smartphone and an emotionally significant physical object (a Minion!), we look to retain and fortify the bonds between parents and children, even when far away.

Objective of product

A pair of toys that, when a paw is squeezed in one, it will take a picture, store it in the cloud, and cause the other to pulse a LED light to indicate that a new image is waiting. The image can be seen through any connected device, like a phone or tablet with access to the cloud. The toys are proposed in the format of Minions, since they elicit a very emotional response in children, and have two sizes: a large one for children a small one, key-chain sized, for parents to travel easily with it.

Target customer

Parent & Child (5+ because of use of tablet/phone to see image)

Context and sequence of operation

Background: Parent often travels for work, so they purchase the connected stuffed Minion and keychain counterpart to share photos with their child.

Process

The first step of the process was to brainstorm ideas. After letting go of ideas related to couples, the team decided that families experience challenges in terms of maintaining a meaningful balance between work requirements and physical presence. We considered that the interaction between parents and children is the one most impacted by absence, as it can cause fear and even lead to separation anxiety disorder.

The team also decided that the format of the product should resonate with children, eliciting a calming and emotional response. Therefore a Minion was chosen, as they are funny, enjoyable and silly “creatures” that make people smile. Even adults =)

We then created a basic sketch of the idea for the basic functionality of the product.

MASTER: push button → servo → iphone → sends to cloud

SLAVE: LED lights up, picture in cloud

With the time available it was not possible to make a stuffed Minion, so the team searched the internet to develop a basic cardboard model for demonstration.

With the creature assembled and painted, the team started with the development of the requirements for the circuits:

2 cameras

2 switches

2 screens**

2 LEDs

jumper wires

2 1kO resistors

2 batteries

For the purpose of this project, it was not possible to actually install the cameras for full functionality, so the items used were:

The code was developed through several iterations that debugged items and rationalized the sequence so it would work within the constraints of the parts available.

The code block fo the parent side of the device is as follows:

//by the activation of a servo motor that presses the capacitive touch
//button on an iPhone camera that is already in camera mode
//Once this picture is taken, it sends it to the cloud using
//IFTTT protocol which syncs it dropbox, when this happens
//a signal is sent to the other matching Minion, so it's light turns on
//when the child acknowledges
