Usability Studies - Science topic

during presentation, A question asked by someone,

Usability study: why it has done. What argument you build by this?

what will be my answare of this question.

My team and I have developed a prototype of an augmented reality mobile application for teaching primary school students human anatomy. We are going to do a usability testing and evaluation with the primary school students using FUN toolkit, and we are also going to conduct an expert review using heuristic evaluation and cognitive walkthrough. Furthermore, we also want the teachers to test the app, and to evaluate the usability in the context of their students' usage. However, the teachers are neither usability experts nor end-users so what is the most appropriate method for them regarding usability testing, survey design etc? Do you have any recommendations for usability testing methods, survey design/template etc.?

I have two sets, one contains 8 experts and the other contains 29 novices. Both evaluated their experience with 5 different questionnaires(e.g. 5-point, 10-point, and 21-points Likert style scales). The responses are non-normally distributed. Which type of non parametric test is applicable to compare the sum? And which is suite to reckon single item? Do I need a post hoc test?

Since most user research or often called UX research deals with software design, I am wondering where I can find information on methods (e.g., interviews, card sorting), tools (e.g., eye tracking), and best practices (e.g., A/B testing) especially in the area of hardware design.

Thank you very much for any advice,

Is there a way to measure Cognitive Affordance of an Interaction Design or has anyone come accross such an idea or an attempt to do so?

Hi,

I have a recorded video in .mp4 format which has cursor movements in it. This was done using a video screenshot software. I need to have a static summary of the cursor movements made on the screen or heat maps for the movements made. Are there any free online softwares for achieving this?

Thanks,

Hi,

I am testing different levels of product/system training to participants (independent variable), with task performance on the product (dependent variable).

Can I generalise the results of this study to another product within the same domain, i.e. from a website to a smartphone application?

I would appreciate if anyone can share any research paper showing results of this or could help me with my query.

Regards,

Design problem- If we have 3 UI concepts: A, B and C and we would like to quantify which one is better out of the three, can heuristic evaluation be used? Constraints: only low fidelity prototypes are available and context is based on participants' envisioning power. Also, how large the sample should be to prevent inter-rater bias?

Hi,

I am planning to conduct usability testing for a motorcycle HMI. The HMI has a joystick which can control the menu of the HMI (only when the biker is not riding the bike). I am thinking of measuring intuitiveness of the HMI, general user experience, Workload and Affect. Intuitiveness of the HMI would be measured for the case when the biker is riding the bike. Other variables would be measured for the case when the biker is not riding the bike. Should I measure any other variables as well?

Any suggestions on how to measure intuitiveness/glanceability of the HMI? I am planning to measure intuitiveness of the HMI as glanceability of the motorcycle HMI is critical considering the biker's safety (Eyes off the road has to be as minimal as possible while ensuring grasp of information from HMI).

It would be also great if anyone can share any literature regarding motorcycle HMI.

Thanks.

Hello professionals, my problem is that my university does not allow me to use qualitative interview methods to investigate the usage context of a web form that I have to create.

It is a form where people should be able to order an individual song from a musician. There is already competition out there, but how can I get the usage context out of a competition analysis?

If you have any ideas, please let me know. It would be great if you could point me to some books which could contain an answer.

GIFT is a free, open-source modular architecture for authoiring and evaluating intelligent tutoring systems.  I am interested in identifying participants for a usability study which will examine how much time it takes to author one hour of adaptive instruction.  The literature shows 200-300 hours, but we believe it is less with the GIFT authoring tools.

Dear online map makers and researchers, could you point to any recent (less than five years) online PPGIS that allows customisation of functionalities to engage lay users in spatial planning?

I am looking to perform comparative usability studies of different online mapping tools for public participation.

I am coming across a number of commercial applications of varying relevance and costs, but many of them are too costly or limited in their range of functionalities. There have been a number of research-led applications, but many of them are obsolete or the researchers have moved to industry or other exciting projects. 

Here is a doi link to the abstract of a recent article, entitled "Toward Cyborg PPGIS":

I was doing research on various usability techniques to measure ERP usability. I found many frameworks but found Purdue Usability Testing Questionnaire(PUTQ) and Software Usability Measurement Inventory(SUMI) match with usability criteria. Need suggestions. Thanks

Most structured observation methods that i found during my research cover an educational context and are very specific. 

I search for a method or instrument that covers indirect performance evaluation (usability tests).

I am trying to understand the differences between the framework and tools, in the field of usability engineering?

I have seen a lot of papers claim that their system or technique is good based on result of post study system usability questionnaire (IBM), but they did not give any reference to compare with. I don't know if there is standard score to compare with?

If something isn’t performing well, you have to go be a detective and figure out why. That’s the essence of doing user testing. Usability testing is a qualitative method of research which is much better suited for answering question about why or how to fix a problem. I have attached a sample template

I looking for such questionnaire to help in carrying out an experiment to measure the usability of different approaches to access mobile apps after being downloaded.
