Mic Directionality

There is the severe lack of internal microphone directionality specifications or any sort of descriptions. They always speak about the battery, the internet and other irrelevant phone specifications. It is very problematic to our project but there are workarounds it but before, that I want to talk about microphone directionality

There are many types of directional mics

A mic that picks up signals from the front and back. useful for interview situations

A mic that is better for the front and sides, can give more directionality in 3 degrees with a little signal coming from the back

Another mic that has three degrees of the signal with none coming from the 180 degrees, captures front and side well.

The ideal microphone for our final project with wide angle for signals to come from to determine the directionality of the person speaking. In terms of applications, this is the most useful one for us.

But like mentioned in the beginning of this post, many companies doesn’t post much about the strength of their mics. In the previous post, I found out that there are many variation in mics even from phones in the same model, as it isn’t needed to be beefed up like a studio mic.

This is a $5 directional microphone from the website above. Cheap with the sound sensitivity of -30dB which might seem short but it is only on a table and might be enough for a table discussion.

It has more details and magnitude more expensive compared to the other one but it has higher sensitivity and high sensitivity.

In terms of prices, we can leave it to the budget of colab and could provide microphone for this activity.

The Prospers and Wealth Walrus

The wealthy walrus mobile phone app.

It is a relatively simple app that follows a wealthy walrus as an investor for people to do hypothetical scenarios.

this is the a question for a certain amount of money.

This is what it looks like after picking your answer. your answers are being compared to the other people around the world who have taken this answer.

Every 5th answer there is a super question, that is worth more money.

It is simple, conversation starters and you can figure out people.

I really like this app because it has very convenient features, it is somewhat competitive because you have a frame of reference to what answer you picked vs all the other people who played the question.

There is the super question that is more harder to answer, its like hard mode which make sit something else

the money, it is the incentive for the actions, it adds a layer of game mechanic that keeps the game interesting.

This app has a lot of features that i really like and could incorporate to our final outcome

Brain storming for studio

What is an ice breaker?

According to google:

icebreaker
ˈʌɪsbreɪkə
noun
noun: ice-breaker
  1. a ship designed for breaking a channel through ice.
    • a thing that serves to relieve inhibitions or tension between people.

Personally, I am a fan of the first Definition.

A thing that serves to relieve inhibitions or tension between two people. I think it usually involves more than two people like a group of people.

But this definition is interesting because it acknowledges the existence of awkwardness, tension or inhibitions that stop people from functioning normally.

Icebreakers are usually used to cut through the heat.

(this post was in no shape or form an advertisement for the Sprite drink)

If it was only this easy to beat the awkwardness, just drink and it’s gone.

But this image above have the classic tells of what is an ice breaker. Beach because it’s hot or a hot day, water because it is refreshing, the guy with a weird outfit consisting of a green underwear or swim suit, almost naked, handlebar mustache and goggles and not what we would call a perfect body, ie a guy hitting the gym. Lastly the giant Sprite bottle with water splashing behind it showing how refreshing it is. Using its awkwardness

Using its awkwardness to be different it can create a certain atmosphere that “this person is not so different from me”. If two people find it funny, it creates a conversation starter, ” Wow that guy has green underwear and he just doesn’t care”. People then get to start thinking, “maybe this person isn’t so different”.

Something funny is great to control the atmosphere.

But I am not going to make a drink and market it as an icebreaker. But I want to incorporate the ideas that the people put behind this advertisement because it really points to an acceptable conclusion that we can think of sprite as an ice breaker.

But a classic childhood icebreaker in the classroom is people bingo.

 

It is simple, a concept of bingo, but to mark out a box, you have to find a person who has the trait or done the activity on the box.

Its simple, its easy to understand and you talk to people. It generates easy conversation starters.
