RE: Research on touch target size

Jeanne, when I spoke to Jennifer Ismirle this is what she mentioned about the publication of their research.



We have 2 papers that will be published with our research: one through HCI International 2016 in late July, and one through HFES 2016 in late September.  The HCI International paper is called: "Touchscreen voting interface design for persons with dexterity impairments: Insights from usability evaluation of mobile voting prototype" (this includes our findings for the dexterity and control groups in our study)  The HFES paper is currently called: "Touchscreen voting interface design for persons with disabilities: Insights from usability evaluation of mobile voting prototype" (this includes our findings for the dexterity, control, low vision, and dyslexia groups in our study)



If she or one of her colleagues could attend a call that would be great.



Best Regards,



Jonathan

I had an action to contact the authors of a CSUN presentation on touch target size to ask about their research.  Jennifer Ismirle answered and is willing to answer questions next week if we have any.  She sent me her slide deck.



The research is on accessible voting on an Android tablet.  She quoted other research as the basis for the size and spacing that they used in the study.  Remember how we started with 9mmx9mm? They used 20x20mm.  I followed her research, which led me to other research etc. One study recommends 30mmx30mm for people with disabilities.  Another showed at least 20x20 with reduced inaccuracy at larger sizes, but less significant.



I started a wiki page.  I encourage others to add any of the information they have from.
