In recent years, environment mapping has garnered significant interest in both industrial and academic settings as a viable means of generating comprehensive virtual models of the physical world. These maps are created using simultaneous localization and mapping (SLAM) algorithms that combine depth contours with visual imaging information to create rich, layered point clouds. Given the recent advances in virtual reality technology, these generated point clouds can be imported onto the Oculus Rift or similar headset for virtual reality implementation. This project deals with the robotic implementation of RGB-D SLAM algorithms on mobile ground robots to generate complete point clouds that can be processed off-line and imported into virtual reality engines for viewing in the Oculus Rift. This project uses a ground robot along with a Kinect sensor to collect RGB-D data of the surrounding environment to build point cloud maps using SLAM software. These point clouds are then exported as object or polygon files for post-processing in software engines such as Meshlab or Unity. The point clouds generated from the SLAM software can be viewed in the Oculus Rift as is. However, these maps are mainly empty space and can be further optimized for virtual viewing. Additional techniques such as meshing and texture meshing were implemented on the raw point cloud maps and tested on the Oculus Rift. The aim of this project was to increase the potential applications for virtual reality by taking a robotic mapping approach to virtual reality environment development. This project was successful in achieving its objective. The following report details the processes used in developing a remotely-controlled robotic platform that can scan its environment and generate viable point cloud maps. These maps are then processed off line and ported into virtual reality software for viewing through the Oculus Rift.

In this experiment, a haptic glove with vibratory motors on the fingertips was tested against the standard HTC Vive controller to see if the additional vibrations provided by the glove increased immersion in common gaming scenarios where haptic feedback is provided. Specifically, two scenarios were developed: an explosion scene containing a small and large explosion and a box interaction scene that allowed the participants to touch the box virtually with their hand. At the start of this project, it was hypothesized that the haptic glove would have a significant positive impact in at least one of these scenarios. Nine participants took place in the study and immersion was measured through a post-experiment questionnaire. Statistical analysis on the results showed that the haptic glove did have a significant impact on immersion in the box interaction scene, but not in the explosion scene. In the end, I conclude that since this haptic glove does not significantly increase immersion across all scenarios when compared to the standard Vive controller, it should not be used at a replacement in its current state.

Ineffective transitional care programs for ensuring the continuation of care from acute settings to the home settings post discharge can result in rehospitalization of elderly patients with chronic diseases. Usually, transitional care should be time-sensitive, patient-centered services intended to ensure continuity of care and an efficient transition between health care settings or home. A patient centered transitional care program was implemented at an outpatient primary care facility to reduce readmission rates. Institutional Review Board approval was obtained.

Twenty adult patients with chronic diseases discharged from an acute setting were identified. A follow up phone call and/or a home visit within 24-72 hours post discharge was employed. The Care Transitions Measure (CTM®) and Medication Discrepancy Tool (MDT®) were utilized to identify quality of care of transition and medication discrepancies. A chart audit collected data on the age of participant, diagnosis for initial hospitalization, CTM score, home visit, and ED visits or re-hospitalizations after 30 days of discharge. The outcome indicated that transitional care within primary care utilizing evidence-based practices is beneficial in reducing readmission rates. A logistic regression showed model significance, p = .002, suggesting that the CTM score was effective for both telephone support (TS) and home visit (HV).

A correlation analysis showed that as age of participants increased, the CTM score decreased, indicating that older adults required more support. A significance p <.001, of a proportional test indicated that readmission rates after the intervention was lower. It is evident that providing a timely and effective transitional care intervention in a primary care setting can reduce hospital readmissions, improve symptom management and quality of life of adult patients with chronic diseases.

This project is called the Zoom Room and it is about the use of virtual reality (VR) for workspace productivity. It is where Zoom and VR meet to form an enhanced productive workspace for users. Equipped with two 3D printers that show how a 3D printer moves and the intricate parts that make up the 3D printer, it is much more than just a standard meeting room. It is a place to analyze machines and meet with others in a virtual space.

AARP estimates that 90% of seniors wish to remain in their homes during retirement.

AARP estimates that 90% of seniors wish to remain in their homes during retirement. Seniors need assistance as they age, historically they have received assistance from either family members, nursing homes, or Continuing Care Retirement Communities. For seniors not wanting any of these options, there has been very few alternatives. Now, the emergence of the continuing care at home program is providing hope for a different method of elder care moving forward. CCaH programs offer services such as: skilled nursing care, care coordination, emergency response systems, aid with personal and health care, and transportation. Such services allow seniors to continue to live in their own home with assistance as their health deteriorates over time. Currently, only 30 CCaH programs exist. With the growth of the elderly population in the coming years, this model seems poised for growth.

Purpose: To implement a non-pharmacologic approach to reduce anxiety in patients receiving radiation treatment.

Background and Significance: Anxiety is a prevalent health problem affecting up to 30% of the general population. Over 95% of radiation oncology patients report anxiety often related to not knowing what to expect during treatments. The current guideline for management of anxiety is the use of benzodiazepines; which can impose a risk to patients. Evidence demonstrates virtual reality videos can be an effective non-pharmacologic approach to reduce anxiety..

Design: Observational cohort evidence based project.

Setting: Outpatient radiation oncology facility in the Southwest United States.

Sample: 40 patients who have not previously undergone radiation therapy, but have been prescribed radiation treatments for malignant or non malignant conditions.

Methods: Patients who had not previously undergone radiation treatments were identified based on chart review and consented for participation in the project. The patient's were assessed for both their general (trait) anxiety and situational (state) anxiety using The State Trait Anxiety inventory (STAI). They were then shown a virtual reality video that walked them through what they would experience during their radiation treatment. The patient's were re-administered the STAI questionnaire following the video to assess any change in anxiety levels.

Variables: Trait and State anxiety scores before and after the virtual reality video intervention.

Findings/Outcomes: A paired t-test was conducted to assess the data. There was a significant difference in the state anxiety scores pre intervention (m = 32.65, SD = 11.47) and post intervention (M = 25.50, SD 8.95), p =< 0.001.

Conclusions: The use of virtual reality videos was an effective non-pharmacological approach to reduce anxiety in patients receiving radiation treatment.

Implications for nursing: The results provide support for the use of a virtual reality intervention as a non-pharmacologic option to reduce anxiety for patients.
