Music based authentication

I have fond memories of playing Resident Evil. In a couple of the RE games, you have to play a piano to unlock puzzles. Batman also has a piano password to enter the bat cave in Batman Begins.

A good password is usually long, random, and easy to remember. Often time, it’s easy to forget a long and complicated password, and easier to remember passwords are predictable and vulnerable to a variety of offline attacks. Musical phrases can be long, hard to replicate, and most importantly easy to remember. Playing a few keys or a musical phrase can be very secure, and it would be extremely difficult for an intruder to replicate with a brute force attack.

While this idea isn't 100% flushed out, I think it would be very fun, and prove useful to the would be vigilantes of Gotham City to keep their hideouts safe.


Augmented Reality Navigation App Senior Project Ideas.

My Senior Project group has decided to switch gears and choose to do an Augmented Reality Navigation application. I use my phone all the time for Google Maps.I know that it would have been great to have a navigation app when we traveled Europe, something that pointed out
Points of Interest, showed me where food is, and told me info about certain landmarks. Our instructor told us that AR is the future of development.
While I'm sure this is true, the market for AR apps is also saturated. We're confident that we can improve upon what already exists. Many of the iPhone apps we found are too busy, with too much text all over the screen. We spend about an hour talking about different possible uses for AR, everything from education, navigation, and entertainment. A major limitation is that looking at the world through your phone is non-intuitive by nature. An idea was to create an app that would help a mechanic take apart an engine. Certain parts of that he needed to work on would be highlighted, it would show him how to do the repair step by step. The major problem is that nobody wants to be holding their phone while repairing their engine. Perhaps when Google Glass and similar tech gets bigger, the AR market will expand. Imagine Tony Stark having to hold a phone to control his suit.


Here's some of the existing AR navigation apps I discovered:
Similar Ideas
  1. Specialized specifically for travelling and finding Points of Interest (POI).
b. Other apps are opened to display info, like Wikipedia.
c. You can choose POI before your trip, and only display those so that your screen is less cluttered.

2. Wikitude,
  • a bunch of open source tools to do a lot of the heavy lifting
  • Android and Apple integration.
  • Extensive how-to documentation, code examples.
  • Used by Adobe, Sony, LG and Samsung

  • Augmented Reality, but the overhead map view is more impressive. It filters the map based on a search query, and then filters your results further using Google, 4 square, yelp, etc…
Search for tacos with google and bing.
Display all of your places in Augmented Reality, show address, phone and distance. Integrates with 60 navigation apps.
  • Integrates with a bunch of APIs. We don’t have to integrate with all of them
Google, Facebook, Foursquare, Twitter, iOS Reminders, Instagram, Panoramio, Flickr, YouTube, Wikimapia, Wikipedia, Factual, Citysearch, Yelp, 2GIS, Zomato, Baidu, Dianping, Yellow Pages Australia, ParkMe

Simple app that shows an overhead view of POI. In augmented reality mode, it displays arrows above head where the places are, and below it displays tabs, where if you click on one, the Wikipedia page opens open.

Notable mention. Talks greatly about AR. Uses Bing.
Great article.

My Senior Project idea has already been done... a lot!

I've been blessed to become trained in the arts of Computer Science, honing my skills at school and at work.
No matter how pro-efficient one becomes in the art of coding wizardry, there's always one limiting factor: having
a good idea. To graduate, we need to do a senior project in a group of 4. We take a semester to create, develop and plan an idea, and another to implement it. 
I'm lucky to work a talented and motivated group of 4, we call ourselves git-mo. (Like the popular versioning software, git and Guantanamo bay combined)
We recently decided upon the great idea of a hiking app, one that would allow users to navigate trails using GPS, even when they were offline.
We were all excited and pumped about the idea until our instructor informed us that our idea probably has already been done before. We did a little research and were greatly disheartened by the sheer quantity and quality of many of the existing apps. It's like trying to invent the light bulb 20 years after Edison with only the hopes of creating something 20% as good. We only have 2 semesters. The creators of these apps have sometimes spent
years developing and refining their apps. 
One of our team members reminded us that Google emerged in a market saturated with pre-existing search engines. They took an existing idea and made it unique. Now they're dominating force in the tech world. 
While, I think just creating a working hiking/GPS app that integrates maps and GPS coordinates will be a miracle just to get working (maybe it wont' be, I've just never done anything like it!) adding a distinguishable, useful, and unique feature seems even more daunting. Like the old adage says, we have to think outside the box. Whatever the case, I'm to the challenge and I remain optimistic!

Here's a couple of the ideas we found:
AllTrails interface, similar to what we want to do.

Senior Project Ideas 2015


I'm a senior and a Computer Science major at the University of Utah. We have to complete a senior project to graduate. Here I list some of the ideas that I have:

1. Diabetes Manager (Preferred Project)

Possible idea for architecture

    University of Utah Medical gave us many suggestions for useful applications. It’s exciting because they have real problems to which they want to see real solutions. They’d be involved and invested into the project. They’d be contributing time, talent and resources. They could help us define what the app will do.

    The main projects discussed were health management tools; software that will help inform patients and help them individualize and manage their healthcare experience. This will also help the caregivers track their patients, and collect meaningful data from them. The app could be specific to diabetes, cancer, surgery, or pregnancy. 

   
While I’m fine with any direction, I have a sister who has type 1, hereditary diabetes. She was diagnosed at 3 years old. It was a scary and confusing ordeal at first for my parents. It was a lot of work to manually write down blood sugar levels, report those numbers to the doctor, and for him to analyze that data. 


   A glucometer, is a device that measures blood sugar levels. They now have Bluetooth enabled glucometers, that can transfer the data via Bluetooth. With that, we could create an app that helps transfer, analyze, predict, visualize, store, and input data from the glucometer. There could be a web and mobile interface, with different views accessible to patients and caregivers. If numbers are dangerously out of the acceptable range, or if there is a continuing bad trend, there could be automated notifications to user and to caregiver. There’s many possibilities and features that could be implemented. 


I have a lot of relevant experience to implement a project like this! 



2. Craigslist++ (Neighborhood Market)




If you Google “Craigslist Scam”, you’ll get pages and pages of incidents and troubles. You probably have been or know somebody who has been on Craigslist who has been scammed. On a more sinister note, you’ve probably heard on the news about murders and sexual assaults that started as a Craigslist postings.

You have no idea who you’re dealing with. You risk being robbed, your house being ransacked, and your person being harmed.
Anybody can post, and no account or verification is required.
I would combine elements used in popular apps.

  1.  eBay’s user system. Users get ratings from other users based on transactions.
  2.  AirBnb, renters and rentees, have to verify their identity, and they also get a rating system.
  3.   Communication within the app would be encouraged for safety.

3. Guitar Master


“Practice does not make perfect. Only perfect practice makes perfect.” Vince Lombardi

While
most of the music world uses sheet music, many guitarists and bassists use “guitar tablature” to read and compose music. There are some programs such as Guitar Pro, which allow you to compose music, read music, and playback songs as midi. Guitar Tablature is open source, and there’s many communities that create tablature for songs, such as http://www.ultimate-guitar.com/. Anybody can “tab out” a song on Guitar Pro, and create a song file. They can then upload this song onto Ultimate Guitar for the world to benefit.

This is great for the community. There’s one barrier; There’s no way to track your progress or get feedback. You can’t tell how accurate you are.  The traditional way is to get a guitar teacher. They can point out areas that you need to work on. The limitation is that you see them once a week, and sometimes you don’t remember what you’re supposed to work on.
There’s been one answer to this, trying to combine the game Guitar Hero, with guitar education.

This game is a great start, but it has two major downfalls:
1. The songs available to play on the game are limited. New songs are added by the developers from time to time, but they cost money.
2. The game layout looks like Guitar Hero, which is non-intuitive to the normal guitar player.


It would be great to have a program similar to Guitar Pro, that tracks your playing. It would let you know which notes you hit, and what percentage of correct notes were played, and track progress. It would be lightweight and would be able to read the vast library of Guitar Pro files.

4. Restaurant Manager

Management uniform

I was a manager at McDonald's for a while, and we had to manage KPIs (Key Performance Indicators). We had to track inventory, sales, food waste, man hours, etc... at the end of the night. We entered all of this data manually into a DOS like command line computer. At the start of each shift, we had to position employees and we had to set goals on sales based on numbers from the same date from previous years and the same day of the week from last week. We positioned employees with a piece of paper, and we had to rely on experience to know which employees would be best in which position. If somebody didn't show up, we had to run into the manager's office to retrieve the employee binder and desperately call and try to find somebody who was available to work. We had to also be looking at the schedule printed on the wall to see who was available. We were supposed to share the goals with our crew, every hour to motivate them. A great idea, but with the current manual system, it was impossible to implement. There's a lot of potential to create software to manage all of this smarter.
