Week 7 #Sensor
https://www.sparkfun.com/categories/23?page=5 (barcode scanner) https://www.sparkfun.com/categories23?page=4 (photo interrupter) My journalistic story would take place around the year 2047. Imagine this. Every American citizen now has a bar code embedded in their left arm. Instead of enforcing “stop and frisk” authorities are now able to stop citizens at any given time period. Authorities can scan the citizen’s arm and view their identification and criminal record if they have one. This scanner can be plugged into a usb device for power. It then creates a laser like keyboard. By this time, technology had literally taken over the world, and was uncommon for someone to not be technologically savvy. People were now finding ways to decode the barcode scanners. This was happening through the use of photo interrupters. By emitting a beam of infrared light from one upright to the other, the sensor can detect when an object passes between the uprights, breaking the beam, and therefore causing the barcode not to work. Then data collected in this futuristic story through both sensors, could be used to determine what demographic is being targeted by the authorities. They could then use this information to create a platform that fights back against the discrimination taking place against them. A field test of this sort would be hard to conduct but could still take place with the use of maybe mobile devices instead of the barcode scanners. With the advanced technology that we now have readily available we are able to track anyone with their location enabled.
