• Concept/ idea sketch: Hug doll for children. Children can play with the doll and can understand how a basic circuit works.

• Inspiration: I inspired by Lego block and Hug doll. I like Lego blocks because users can build anything from tiny blocks but blocks have to be put together to build something. Children can learn a message of working together. Although I like Lego blocks, I don’t like the texture because it’s too hard and sometimes cold so I use fabrics and yarns to show soft and warm feeling.

• Precedents:  Snap Circuits Alternative Energy Green / This precedent is an electronic kit for kids.  Kids can learn about “Green Energy” options and they can build over 125 projects by using different parts in the kit. It contains over 40 parts. also, a paper instruction is included in the kit so kids can learn the theory with the projects.  I think this precedent is really useful for children who like to learn basic electronic circuits but I don’t like texture and design because it’s only focused on training circuits.
• User testing + feedback: I did the user testing on 3 people. All of them really likes the design and textures.
• user A: Love the texture and design of the dolls but the connectors can be more developed in hand shape so it feels like friends are holding hands.
• user B: She likes that it doesn’t look like and feel like a circuit. Even small girls will be very interested in the play.
• user C: She likes that children can easily make a story with this dolls. While they play with this dolls they can naturally know how a basic circuit works but she mentioned that I could change the battery to 9V so the users can connect everything together.

• Challenges you faced: It was really hard to make all different parts into dolls because I avoid mechanical feelings. It was really time-consuming project to build most parts by just hand sewing and crochet.

• Future iterations: I like to develop more parts such as a temperature sensor doll, a sound making doll or a servo doll. Also, I want to develop the connector design to look like hands.
