Sketches During Brainstorm
Project Choice Justification
One of our ideas was to use LEAP as a means of authentication using one’s face, a gesture, or a physical object. To us, the most clear application of this is for authenticating web services, such as for logging into one’s email or social media accounts. However, this kind of authentication is easily extendable to systems beyond web applications: for instance, one could use this to unlock doors or to control who can drive your car. Furthermore, the flexibility of LEAP means that any small, handheld objects could be used to identify you, such as a small tchotchke. With facial recognition, the username/password pair becomes obsolete because it is exceedingly expensive and difficult to recreate someone’s face to the precision required if you wanted to gain access to their accounts. The downside to this is that you’re exposing your credentials to everyone you walk past, so perhaps identity theft could become a real issue. However, this can be easily rectified by using a hand signal or handheld object to confirm your identity, like a password, that would be easy to keep hidden or hard to replicate. All in all, this seems like a very useful device with broad applicability that would allow people to spend more time going on with their lives and less time worrying about lost passwords and keys or simply taking time to login to sites, all in all with a high level of security.
Games are generally really fun to play but often have no real-life applicability, such as the Guitar Hero franchise, whereas some tasks in real life can be somewhat droll to learn. Enter the digital dance floor, which could teach you to dance by lighting up tiles for you to step on in time to music. Here, the idea is that you would stand on a dance floor, which is composed of a set of transparent, square tiles. Each tile would be controlled by a single light source, the set of which would be managed by a computational device. By storing and replaying a pattern of lights over time, one could effectively recreate the steps of many dances. Then, using force-sensitive resistors underneath each tile, the accuracy and timing of one’s responding dance steps could be measured and quantified into a score, which would then be recorded at the end of the game. Additionally, multiple panel colors could allow for more than one player to participate in the game at once. This idea is also extendable, as there are many other modes for operation one could conceive of: for instance, you could have the lights respond to pressure, creating a dance floor that tracks how people move along it and lights up squares beneath people on the dance floor, or you could play a full-body version of Simon Says.
Problem Description & Context. Reliable user authentication has been a perennial problem in human-computer interaction. How can a system verify that the user is who he/she claims to be? The prevailing solution varies on and off the computer screen. Inside the web browser, username/passwords systems ensure that the desired user is the only individual who knows the correct combination of inputs. Outside the computer, locks, keys, and RFID cards dominate the physical world to open doors and grant physical access. These solutions are not without challenges of their own. For example, what happens when a user forgets his/her password? The password recovery process is prone to hacking by email and phishing attempts. In the real world, physical keys and cards are liable to misplacement. We’ve all had a time we lost a key during our day-to-day bustle. Finally, an underserved segment of our population are those disabled individuals who cannot easily use existing forms of authentication. Consider individuals who have difficulty typing– username/passwords are a nuisance. Similar challenges are presented to individuals who have difficulty with traditional locks and keys. Our overall goal is simple, fast, reliable, user authentication.
Target User Group. Our target user group boils down to two types:
- Disabled Individuals– For reasons related to limited finger movement or arm motion, these individuals experience difficulty using locks/keys or username/password typed into web sites. They desire access to their favorite web sites and physical rooms behind locked doors.
- Public Computer Users– Institutions like a university are full of public computers that require username/password authentication. The time spent authenticating by keyboard could be better spent serving another user, thus reducing the overall demand for computing resources over time. These institutional users desire speed– whether its university students trying to print a paper before class or a business professional trying to get a meeting started as quickly as possible.
Technology. Leap is a sensor that is capable of detecting 3D motion for 3D objects. While photos and videos are a 2D mapping of the 3D world, Leap is able to capture the full scope of 3D reality. This benefit allows our idea to become more viable. In the case for facial detection, the Kinect or a photo app would not suffice because authentication can be thwarted by simply placing a picture of a certain individual in front of the sensor. However, this wouldn’t be a problem for the Leap since the 3D would take into consideration the depth of the image. For a 3D object, due to the sensitivity and precision of a Leap, other systems may not be able to detect the subtleties of our authentication object.
