Wardriving is when prospective malicious hackers drive with a portable computer to sniff out and map potentially vulnerable networks. With the advent of smart homes and other Internet of Things devices, this poses the possibility of more unsecure targets. The hardware available to the public has also miniaturized and gotten more powerful. One no longer needs to carry a complete laptop to carry out network mapping. With this miniaturization and greater popularity of quadcopter technology, the two can be combined to create a more efficient wardriving setup in a potentially more target-rich environment. Thus, we set out to create a prototype as a proof of concept of this combination. By creating a bracket for a Raspberry Pi to be mounted to a drone with other wireless sniffing equipment, we demonstrate that one can use various off the shelf components to create a powerful network detection device. In this write up, we also outline some of the challenges encountered by combining these two technologies, as well as the solutions to those challenges. Adding payload weight to drones that are not initially designed for it causes detrimental effects to various characteristics such as flight behavior and power consumption. Less computing power is available due to the miniaturization that must take place for a drone-mounted solution. Communication between the miniature computer and a ground control computer is also essential in overall system operation. Below, we highlight solutions to these various problems as well as improvements that can be implemented for maximum system effectiveness.

American Sign Language (ASL) is used for Deaf and Hard of Hearing (DHH) individuals to communicate and learn in a classroom setting. In ASL, fingerspelling and gestures are two primary components used for communication. Fingerspelling is commonly used for words that do not have a specifically designated sign or gesture. In technical contexts, such as Computer Science curriculum, there are many technical terms that fall under this category. Most of its jargon does not have standardized ASL gestures; therefore, students, educators, and interpreters alike have been reliant on fingerspelling, which poses challenges for all parties. This study investigates the efficacy of both fingerspelling and gestures with fifteen technical terms that do have standardized gestures. The terms’ fingerspelling and gesture are assessed based on preference, ease of use, ease of learning, and time by research subjects who were selected as DHH individuals familiar with ASL.

The data is collected in a series of video recordings by research subjects as well as a post-participation questionnaire. Each research subject has produced thirty total videos, two videos to fingerspell and gesture each technical term. Afterwards, they completed a post-participation questionnaire in which they indicated their preference and how easy it was to learn and use both fingerspelling and gestures. Additionally, the videos have been analyzed to determine the time difference between fingerspelling and gestures. Analysis reveals that gestures are favored over fingerspelling as they are generally preferred, considered easier to learn and use, and faster. These results underscore the significance for standardized gestures in the Computer Science curriculum for accessible learning that enhances communication and promotes inclusion.
