Usability Evaluation

For this project I worked as part of a team of four students to conduct a website usability evaluation for a social media start-up called SilOOette which was based in the Media Cube at IADT.

SilOOette’s Login Page

SilOOette aimed to connect individuals through their interests. Users could follow topics rather than people, thereby choosing only the topics they want to see and creating their own unique news-stream.

“Cut through the noise and create a filtered News Stream, one filled only with the stuff you care about.”

 

Testing

Our team compiled a script to brief our users on the testing process. It was felt that this would help to put them at ease and make them aware that the focus of the test was the website itself rather than their own ability. It also allowed for consistency in the testing process as each member of the team carried out tests individually. Each user also signed a consent form and completed a pre-test questionnaire to assess their social media use.

Test scenarios were created by the team to replicate real life use of the website and identify user pain points. The purpose of these scenarios was to maintain consistency between user tests and to give our testers clear instructions, and so avoid placing them under undue stress.

Users were required to sign up to SilOOette using a dummy email address. They were then directed through the test scenarios which required them to follow topics that interested them, edit their profiles, connect with another user, find specified topics, create a post and link content from an external website. Camtasia was used to record the tests with users’ permission. A total of ten users completed these tests, after which they completed a post-test questionnaire.

 

Data Analysis

Once all tests had been completed the data was analysed by the team. The data gathered included a five second test to give initial impressions of the website, the length of time taken to complete each scenario, user pain points, pre- and post-test questionnaires and general comments.

In general users liked the appearance of the website. However there were numerous user pain points identified which the team grouped into four main issues:

  • Connecting to other users was unsatisfactory due to the necessity to click through users individually, plus there was no bio information about users
  • Navigation difficulties
  • Confusion about editing profiles and understanding some elements of same
  • Issues around creating and posting content were the most problematic, due to the fact that SilOOette’s topics of interest was split into sub-topics called channels – this caused great confusion and irritation for users as the difference between topics and channels was unclear

 

Reporting Results

The team interpreted the results of the data and produced a comprehensive report which included

  • Introduction and brief summary of the website’s aims and uses
  • Identification of the usability goals that were tested (i.e. effectiveness, efficiency and engaging) along with the type of usability testing that was being conducted (i.e. ease of learning)
  • Summary of the testing documents used: script, consent form, pre-test questionnaire, test scenarios, data collection document, post-test questionnaire
  • Description of the tests carried out and summary of the data gathered, including our own analysis and interpretation
  • Conclusions and recommendations for design changes

 

Some of our recommendations to improve the user experience of this website were:

  • Improve navigation between pages
  • Include a search bar
  • Explain the meaning of channels and topics
  • SilOOette rated it’s users on integrity which some testers interpreted negatively, the team suggested substituting another word
  • Include a tutorial to introduce the website and it’s operation
  • Improve the user experience of connecting to other users, e.g. provide a list of users to connect with

 

Conclusion

As this was a team assignment, it was necessary to ensure good communication and teamwork between group members to ensure it was completed to a satisfactory standard. A facebook group was set up and tasks were divided up between team members. This approach worked well and I enjoyed working on this project. The usability evaluation was completed on time and was well received, both by the module lecturer and by the people at SilOOette.

The grade received for this project was an A.

 

 

 

Group IT Project

This project brings together students from the two streams of the Applied Psychology course (psychology with technology and pure psychology) to work as a team on production of an IT solution that is underpinned by  significant, credible, research-based psychological knowledge and understanding.

This project is still ongoing and culminates in the development of a prototype and it’s showcase at an Interactive Display in May of this year.

I have included this project in my portfolio because it brings together many of the skills I have honed during my degree and applies them in the development of a proposed solution to an identified user need, from the idea stage right through to the high fidelity prototype.

A Scientifically-Researched User-Friendly Nutrition App

The Team consists of four students, two from the pure psychology stream and two from the technology stream.

As one of the two technology students, the skills I brought to the team included:

  • an understanding of user-centred design principles and their application
  • knowledge of the process of user testing and iteration
  • experience compiling low and high fidelity prototypes, using software like Photoshop, Illustrator & Axure

 

The Idea – Various ideas were discussed in the early stages. One area of common interest between team members was nutrition – specifically the fact that there is a lot of contradictory information available which is confusing for the layperson, plus there are some important areas which are not sufficiently highlighted.

In spite of the huge number of nutrition apps that are available, or perhaps because of them, we felt strongly that there is an existing need for a user-friendly app that provides unbiased, clear and scientifically-researched information to help users in making healthy food choices. Some possible features we discussed included:

  • a barcode scanner which provides nutritional information in a traffic light system so that users can easily make informed choices about the food they buy
  • information about the food pyramid illustrating to the user how many portions of the various food groups they should aim to consume
  • information about how diet affects health, with a special focus on mental health and immunity
  • clear scientific information about various popular diets, e.g. gluten-free, paleo, vegetarian, vegan
  • link to a website that would go into more detail

 

Background Research – in order to investigate this further we researched a number of existing nutrition apps.

One of the most relevant to our proposed IT solution is Fooducate. This app includes a barcode scanner with traffic light system for displaying nutritional information, and it gives feedback on quantity and quality of daily consumed calories. However the mobile app is not available outside of the United States.

Another nutrition app that we researched was My Fitness Pal, this app allows users to keep track of their diet and exercise patterns in order to help them loose weight. Although this app had some similarities to our proposed solution, we felt it was aimed at people who are actively seeking to loose weight while our vision was an app that would educate users about food and health.

We decided as a result of researching many more nutrition apps that it would be useful to include recipes appropriate to foods that the user scanned, as well as a feature to save favourite recipes.

 

Identifying a Need – at this stage we decided to carry out a survey to ascertain the level of interest in our proposed solution. A ten question survey was compiled on Survey Monkey and circulated via social media. Results of the survey showed most interest in 2 areas: the barcode scanner and information on how diet affects physical and mental health. Due to the low level of interest in the various diets (gluten-free, paleo etc) we decided not to include this in the prototype.

 

 

Developing IT Solution – the first step in development was to put ideas on paper. We drew up paper prototypes and user tested them as a mobile app using POP and received some very useful feedback which was incorporated into the high fidelity prototype. Some of these suggestions included

  • link the barcode scanner with the food pyramid so that when a user scans an item, the user receives feedback as to where it belongs on the food pyramid
  • record daily calorie intake and compare it with recommended levels
  • clearly explain nutritional jargon
  • include a section on weight in the health section and explain the effects of being overweight on health
  • navigation was confusing and needs to be more consistent
  • include a search function so that the user could search for recipes / health content

These suggestions were implemented into the design and work began on the high fidelity prototypes, which are currently being developed. Some of the high fidelity screens can be seen above.
