Mobile hemolysis detection in whole blood samples

A system for hemolysis detection, where the system generally includes--individually or in combination--a containment apparatus for holding the blood sample and a software application for analyzing the blood sample. The containment apparatus houses the sample therein, and blocks out any light from penetrating the apparatus and reflecting off of the sample. In conjunction, the software application uses camera color for processing the color of the sample to determine the hemoglobin level in plasma based on the color

Development of User Feedback-Based Optimized Encoding System for 3D-Printed Tactile Maps

The wide availability of 3D-printers makes possible the simple creation of tactile maps for individuals with blindness. However, to be useful, these maps have to be designed using feedback from the future users. In this study, we worked with fifteen individuals with blindness to develop an optimized encoding system for 3D-printed tactile maps for building interiors. Based on their requests, we focused on the development of maps with information about safety routes and emergency exits. Additionally, users identified a set of important physical objects to be encoded on the map. After that, multiple encodings were evaluated individually and when integrated in maps. This resulted in a set of optimal encodings that was most positively perceived by all participants

Development of the Tactile Map Creator (TMC) Application

There are multiple studies demonstrating that 3D printed maps are important to people with blindness. When designed properly, they help users by improving safety and mobility and allow people with blindness to efficiently learn spatial information from the map and plan their travel prior to navigation. However, tactile maps are still not widely among people with blindness, as they are not readily available to them. Creating maps for each person needing a map of a certain location currently requires help from an individual with advanced technical training. They need to use specialized software for 3D models that personnel from disability services and family members of people with blindness usually have no experience with. The goal of this research is to design and implement software that can be used for the automatic generation of maps and be accessible to the general public. Our hypothesis is that by automating all the challenging steps (generation of the 3D model and drawing of optimally designed symbols), this will lead to increased usability and acceptance. Here, we demonstrated an early prototype and evaluated our hypothesis in a user study. To assess the success of this approach, participants answered questions about the process, usability, and social impacts of the software. Overall, participants liked the application because it was easy to use and allowed them to create custom maps with appropriate tactile-encoding features that provide meaningful information to the end user
