Visual&Sound Cues => Mechanical

This is my dog and her favorite toy: a blue and green rubber ball. She recently got into the habit that when she wants us humans to play the ball with her and we don’t give her attention, she would roll the ball into places she can’t reach, usually under a desk or behind the TV set. Then she whines until someone gets it for her, which could be minutes if no one decides to get it.

The process of retrieving the ball involves bending down, looking for the ball under table, get it out with a 6ft long stick or with hands. And sometimes when I have my headphones on, I don’t hear her whining.

This is frustrating for both my dog, and my family. So I came up with the idea of making a device that could fit under the table. It can detect the dog’s whining sound, move under the table to find the ball, and push the ball out.


Sound/Visual Cues Transformed into Mechanical

Honks can be really important information sources for drivers. This can be problematic for people that are deaf or if someone is listening to music loudly in the car. One possible solution is to have a visual cue, but driving already relies so much on visual input from the outside world and indicator lights on the dashboard that it would be overwhelming and not very helpful. Because of this, a mechanical notification such as the steering wheel vibrating would be a really helpful alternative. The wheel can vibrate with different frequencies based on the frequency of the honks and this information would be easily passed on to the driver as at least one of their hands would be on the wheel.

Another idea I had was if someone is blind they need to rely on hearing or haptic feedback. Oftentimes I get someones attention by saying something and if they don’t hear me I will wave my hand a couple feet in front of their face. If someone who is blind who’s working on something say on their computer while listening to something would not be notified by either of these actions. I would potentially feel awkward about just walking up to them and tapping their shoulder. If there was a device that they could wear that would tap them for me weather as a watch or armband it would be really useful.

Translating Image to movement

First idea (for accessibility):

Currently, I am painting my sculptures. The problem is, though, that I have a limited amount of ventilation in the studio space because I am currently working in my room, so the paint doesn’t dry as it should. And that is a big problem for me because the paint I use is toxic to the human lungs, which means that when I smell it, it is already too late.

So I have designed a fan with LCD, one of the gas sensors from my last project, and an RGB sensor that interacts with my work and space. So the LCD screen will display the value of gas from the paint. If it is in a high range, it will activate the fan. Also, the RGB sensor will detect the color difference on the sculpture. It will compare the colour value of before and after, and using millis function after a certain amount of time has passed, it will activate the fan. The fan will not only help me with ventilation but also speed up the drying process.

Second idea (for myself):

As a sculpture artist, I always wondered installations kinetically interacting with the audience. What I am imagining to design in this is expected to be used in my future project of expressing the mob pressure.

After some mapping, the arduino RGB sensor gives the frequency of each RGB value. Therefore, one could set a range for each RGB value and make each servo motor move differently in angle. For example, when each value falls from 0-20, each assigned servo motor could move. Therefore, when each servomotor senses certain colors of clothes or shoes, it will turn towards them.

The more effective/accurate version would be using the PIR sensor I used before. When someone approaches and PIR sensor value turns to 1, the servo motors can turn towards the person at the same time. Or have each PIR sensor for each servo motor, so when a person gets closer to one motor, each motor can look away from the person to deliver a more excluded feel.

They all turn towards you when the PIR sensor senses the movement

I guess it is kind of like a reversed mirror, just that it doesn’t show you your reflection, but it reflects your movement.

Or even it will be nice to have wheels attached so they follow you. That will be extra creepy.
