“Virtual Counselor” Cognitive Support System

The UCSIM | Center for Simulations & Virtual Environments Research recently partnered with Dr. George Richardson in the CECH-Human Services department on a funding proposal that was awarded to develop a working prototype “Virtual Counselor” Cognitive Support System mobile application.

The Virtual Counselor (VC) is a novel computer program that enables users to achieve behavioral change by providing experiential learning via realistic simulations that engage users in cost-effective and safe virtual environments. The VC stands apart from existing computer-based educational and treatment applications because it is content-neutral and applicable to a very broad range of health-relevant behaviors. In addition, the VC outputs graphical depictions of client cognition that can enhance client-professional counselor communication and inform clinical decisions.

UCSIM Welcomes RevolutionUC Hackathon!

WELCOME REVOLUTIONUC HACKATHON!

RevolutionUC is a college hackathon, hosted every semester at the University of Cincinnati. A hackathon is when people who are excited about programming come together for a weekend and collaborate to build cool things. Entrepreneurs, designers, and developers work in teams to create hacks and apps for web or mobile platforms – in our case, these creators are university students. Projects will be judged based on creativity, technical difficulty, polish, and usefulness.

 

UCSIM HACK OPPORTUNITY #1:  VIRTUAL REALITY CAMPUS

campus_demo_background_home

Using a virtual model of the real University of Cincinnati campus and an Oculus Rift DK2, develop an interactive application that would help incoming freshman learn more about living, working, and playing in and around UC.  Your application should take advantage of the sense of presence and immersion that virtual reality provides, and may address any of the following themes: Campus Safety, Finding Classes, Virtual Tours, Campus of the Future.  Be sure to consider the end user experience and how to minimize simulator sickness in your design!

UCSIM HACK OPPORTUNITY #2:  THE GOOGLE GLASS-ROOM

google_glass3

Wearable computing will change the way we interact with our devices and the world around us.  Develop an application for Google Glass that will improve the educational experience in any of the following topics: Augmented Reality Classroom or Lab, Scheduling and Organizing, Personalized Education, Collaboration & Teamwork.

JUDGING CRITERIA

Entries will be judged based several criteria, including:
  • Problem Definition:  How precise and relevant is the real world problem or opportunity? How interesting or difficult to resolve – functionally or technically – is the problem being challenged? For this criterion, we only focus on the problem challenged, not on the solution created to solve this problem.
  • Solution Design & Innovation:  Does the application approach a new problem, or look at an old problem in a new way? Is the solution completely innovative or does it rely on an existing concept/technology? Does the application impact a large number of people very broadly, or impact a smaller number of people very deeply? To what degree does the application actually solve the current problem?
  • Practical Application:  Is the application technically viable? Would people use this product?  Is this solution only theoretical or does it have a realistic application for educational purposes? (Not necessarily here and now, but eventually in the future and/or for certain markets).
  • Functionality:  How functional is the prototype?  Does the prototype demonstrate lots of functionality at a high level or is it more limited in scope?
  • Presentation & User Experience:  How well is the application presented?  Is the user experience positive or negative?  How intuitive or functional is the UI design?

UCSIM Staff will be available during the competition for guidance and mentoring.  Good luck hackers!

 

 

Virtual Reality as a Powerful Tool in Medicine

Virtual Reality Therapy (VRT) is one of the most important applications of Virtual Reality (VR) and Simulation technology. VR has proven to be an efficient tool due to the ability of a computer to provide visuals, sound, and in some cases other sensory information such as touch, which replicates a physical situation as closely as possible, but only in a virtual sense.

For example, PTSD (Post Traumatic Stress Disorder) can be treated with VRT. It is a disorder that occurs when an individual experiences traumatizing situations which embeds a feeling of powerlessness and horror in the individual. Through VR, more than 70% of soldiers who were suffering from PTSD after the Iraq war have seen improvements. Similar results are obtained from the use of VR in Computerized CBT (Cognitive Behavioral Therapy) where at a research level, several mental disorders have been diagnosed accurately and treatment has been prescribed.

With the advent of new consumer level VR technology, such as the Oculus Rift and other HMD (Head Mounted Display) systems which provide the user with visual experiences that are very close to the real situations, and other peripheral developments to track movement and motion, it is now possible to provide all sorts of sensory information to the user for any given situation.

Using this computing capability to treat and help people suffering from perennial and genetic disorders such as Autism, Down’s Syndrome (DS) and other genetic disorders is a new area of exploration for using VR in medicine and treatment. Currently children suffering from such genetic disorders are given special training by qualified and dedicated teachers and parents who work in co-operation with them day and night in order to provide assistance in dealing with real life situations. However, there are limitations to this method of teaching which may be augmented by including VR based teaching with human assisted training.

The use of Virtual Reality to tackle this issue has a great future from both a medical and business perspective. The power of computing and providing sensory information is the key to making this technology possible. Researchers at the University of Haifa, Israel have made excellent studies on the use of VR to treat Autism. Their collaboration with MERL’s Diamond Touch (DT) hardware, a multitouch interface to assist learning, has been an extremely powerful tool in improving communication and social skills along with improving academic and functional abilities.

Another similar situation is in simulating traffic signals and road crossing scenarios which cannot be implemented in reality due to the inherent danger of the scenario, but in a virtual reality situation, those suffering from anxiety can receive treatment in safety. This research performed at the University of Haifa has been extremely effective in treating children suffering from Autism.

Although using VR for treatment of such disorders is becoming more accepted, the idea of further research and developing this technology to a consumer level product which enables best treatment techniques from one part of the world to be available to every individual suffering from this disorder is still in its infancy. The use of any technology is judged by its potential to influence and change humanity, and the ultimate goal of many VR researchers is to move beyond gaming services to develop technologies that can change individuals’ lives and help them become better, more capable and healthy people.

UCSIM Welcomes INTERAlliance IT Careers Camp 2014!

For the ninth year, the INTERalliance is running its renowned “IT Careers Camp” program at UC, hosted by the IS Department of the College of Business, NKU College of Informatics, and Miami University, Oxford School of Engineering and Applied Science. Twenty students per week live in the dormitories and compete on four teams of five students, with each team sponsored and branded by a company (e.g., “Team P&G” versus “Team Cintas” versus “Team Kroger”, etc.).

The students go to a different sponsor site each morning and compete in problem-solving “Olympics”, with the events built around real-world business challenges encountered by the host sponsor company. The students have lunch with the IT management team at the company and discuss career opportunities in IT and applied technology at that firm, and then return to the host university to work on their capstone project – their entry in the “Technology Optimized Business Enterprise” or “TOBE” competition.

In this weeklong design contest, the teams attempt to conceive a business plan for a new business – a social enterprise – that can leverage IT and technology to create substantial employment and career opportunities for people with disabilities. On Saturday each week, the teams present their designs to a panel of judges from the local agency supporting disabled clients and the sponsors.

UCSIM is excited to participate in the event and welcomes the INTERAlliance camp students to the exciting field of immersive technology!
