Revised Design Specification

Problem Statement Due to the loss of vision, the blind and visually impaired must learn to navigate in complex environments and public spaces using their other senses. Therefore, a product that can connect the other senses is a necessity. Product Description Our product is a pair of glasses with ultrasonic sensors that connects to a module of arduinos and a battery pack. The glasses will connect to the module through contained wires that lead around you back. The glasses contain one/two sensors that pick up objects in front of the user and send an output to the module. The wires that lead through the back connect the glasses to the main module, the sacrifice of comfortability is needed to optimize the effectiveness of the overall product. The main module will reside in a fanny pack with a hole in the back to lead the wires through. Operation The product will use an ultrasonic sensor on a pair of glasses to detect any objects that may obstruct the path of the user. The ultrasonic sensor will send a signal to the arduino which will then transmit an audio signal to the bone conduction or the piezo buzzer to alert the user. Justification The product will improve the quality of life for both the visually impaired and everyone else by allowing for a better interaction between the two. Additionally, it will help prevent injuries by alerting the user. This product will fix a major problem with the walking cane which is detecting objects above their lower half. The product provides better object detection than other devices made to help the visually impaired while keeping any batteries and other hazards away from vital body parts. Appendices For brainstorming we had multiple ideas going around we could not decide on. For example, we had to discuss glasses or a headband. Additionally, we needed to decide on whether or not we would have all of the devices on one object or multiple to better distribute the weight. Furthermore, we needed to decide whether we use a piezo buzzer or bone conduction. Criteria- Safety and Legal Issues Potential legal issues that may arise would be from this product not properly accomplishing its tasks or the product itself causing harm to the user This is seen in the weight distribution of the product along with proper casing around the battery and its placement The technology should be in a proper location with proper casing or buffering between the person so that it does not cause discomfort or harm from overheating, frayed wires, etc. Function The product needs to recognize an object that will obstruct the users path and warn them in fast enough for the user to move out of the way and avoid the object The product must recognize an object within 15 feet of the user and warn them within one second so they may have at least two seconds to respond to any stand still obstacle. (Timing may change due to the climate) The product must be durable enough to withstand common weather conditions and collisions with other objects. Additionally, products must be properly designed to where the devices do not raise each other's heat or other potential hazards. Maintenance on the product will be very little due to the only maintenance needed being the recharging of the battery and cleaning of the sensor to ensure it still works Any required fixing of the product must be left to professionals as the devices inside may retain damage or harm the user Customer needs The customer needs a product that will maximize their safety in public spaces This includes keeping them safe from the product itself The customer wants a comfortable product that will make it easier for them to interact with the human population and not have as many difficulties Ergonomics The product needs to be a good fit for the user so that it stays on during travel while also being as comfortable as possible For the most efficiency, the glasses must be worn the correct way so that the sensors face in front of the user and can detect the objects The sensors must not be able to touch the surface of the users skin and the fanny pack must have proper materials that do not allow the devices to be affected by any external forces. Materials The only specific materials needed are the ones required for the devices that will be attached to the glasses and fanny pack Materials used will be able to withstand heat and water The sensor will correctly and accurately detect objects even in humid and rainy environments Target Cost The anticipated consumer cost of the product is in the range of $70-$100 Form The product will be in the form of glasses It cannot be to big or too heavy and cause user trouble and annoyances during usage Aesthetics The visually impaired still care about the way they look, so we have to make sure that just because they can’t see, doesn’t mean we should disregard the way they look The aesthetics should also be able to work alongside the functionality of the product, neither one of these can be more focused than the other. Specifications- The glasses will be holding the sensor, the rest of the devices such as the battery and arduino will be stored separately in a fanny pack. The sensors that will rest on the glasses will pick up objects from a distance of 15 feet and will provide an audible output when it detects something within the 15-10 feet range. The audio output that comes from the sensors will be transmitted through bone conduction and will be accounted for when dealing with timings by giving it a 1 second processing delay.
