With HouseOnFire (HOF) having a party at your house will be easier and funnier. HouseOnFire will assist you in the whole process of planning and hosting any kind of party, with the minimal effort. It suits users that want to have fun, from teenagers to adults and can be installed directly in your home.

With the HOFApp – the mobile application provided by HouseOnFire – everyone will use his personal profile where to set his preferences about music and group his friends by lists, such as high school mates or football team. When you're planning the party, you only have to choose the list of friends you want to invite and eventually integrate it. Thanks to the app, the system will analyze the data and suggest playlists to be played during the night.

After the planning part, HouseOnFire will assist you during the party by sensing the environments and modulating lights, volume and type of music, recognizing the most typical moments of the party, such as the “Happy Birthday”. You will have to worry about little more than having fun.

You will have two rooms, one to chat and the other to dance. In the dancing room, HOF will be able to understand the right moment to raise the volume to the top and lower the lights, through the careful analysis of your guests movement. In the chatting room, it will help creating a relaxed atmosphere, analysing the different tones between music and people words. It will also help you send your friends home late at night, lowering the music to calm people down, and you will avoid paying a huge fine for disturbing your neighbor.

HOF will be as a friend always listening to you. When hearing given keywords or phrases, it will assist you, acting as you wish. It will sing “Happy Birthday” with you at birthday parties and play the music you want when asking for a specific song.

HouseOnFire is certainly the best solution to organize a house party, allowing you to relax and enjoy the night with your friends without the worries and responsibility that too often bother the owner.

The goal of the system is to help organizing and managing a house party. A mobile application allows the user to collect guests data and to interact with the intelligent core. During the party, the system controls the atmosphere in the environments, setting music and lights and adapting its behaviour based on data collected through bluetooth sensors and microphones.

The system is supposed to control two environments: one for dancing and the other for chatting. In the dancing room there are speakers for music, bluetooth sensors and wireless controlled lights. In the chatting room there are speakers for music and a microphone.

Sensing

The system is able to sense if someone is dancing, in the dancing room, and if the participants are talking, in the chatting room. It can detect presence of movement and volume of talking in order to actively adjust playlists, music and lights levels.

Reasoning

After the user decides the participants to the party, either individually or from a saved list, according to previously organized parties, the system memorizes the choise, and based on their preferences it creates different music playlists for the party, from which the user can choose. During the party, the system actively changes music and lights, according to data collected through sensing. Furthermore it is able to distinguish music pattern from human voice.

Acting

If the system detects the presence of someone, moving in the dance room, it will lower the intensity of lights and turn up the volume of music. On the other hand, if it hears people talking in the chatting room, it will lower the volume and increase the lights, according to intensity and quality of conversation.

Interacting

The system can be controlled either by smartphone, or simply talking to it, being able to recognize some basic-keywords, for example the user can ask for a specific song, or just to skip one, as long as it is present in his database.

Sensitive

It senses the environment measuring the noise and the movements of the people in the rooms.

Adaptive

According to the users’ preferences, it is able to organize the perfect party, so that each party will be the best possible one and each time different from the previous one.

Ubiquitous

It can be applied in every house and the app can be easily installed in your smartphone.

Responsive

It is able to adjust the volume of the music and the intensity of lights

Transparent

The system is provided with a set of small sensors, that can be installed in the environment without being perceived.

Intelligent

It can act in different ways according to the data it collects and the information it already has.
