At Home

Smart Home System

Take a look



The At Home system can tie home appliances and electrical fixtures together so they perform as one unified digital system with the help of an intuitive user-interface. The process will be quick and simple. The aim of the system is to help users who might be intimidated by technology.

Home automation systems face four main challenges; these are the high cost of ownership, inflexibility, complex interface, and difficulty achieving security. The complex interface makes the system inaccessible and difficult to interact with people who might be technologically inept.


The At Home system will be able control the entire home environment, ranging from lighting, thermostat settings to audio-visual playback is placed at the hands of the user. Users who are not tech-savvy will be able to use this system since it will be heavily influenced by real world interactions.



Home is where we spend a lot of our time. People today own multiple appliances which have become an integral part of their life. Nearly every aspect of the home can become "connected" - the living room, the kitchen and the garage.

A system to control all these appliances can make our life more convenient and safe. It can also comfort help in overall cost reduction and energy conservation.

Contextual Inquiry

User Interviews

We interviewed 12 participants. Some of the participants were interviewed individually by the team members, while other interviews were conducted in a group of two.

The participants were aged between 23 and 65 years. They came from different occupations; graduate student to a marketing manager.

We asked the participants about their personal choice of needs, and the features they would want to use or would like to see in the smart home system.

Affinity Diagramming

After finishing the interviews, we met within 48 hours for brainstorming and affinity diagramming. We generated about 244 affinity notes for the atomic diagram which were initially grouped according to the participants but were later regrouped according to their affinity.

We eleminated the repetitions and grouped the notes under different labels. We were able categorize 5 primary groups i.e. tech savvy group, a group for whom comfort is important, a group for whom security is important, a group who wants the interface to be really simple (Anti persona) and the last group who would want the master control of the system (requires different profiles).
