Dear PPTG members,
Thursday morning, October 13, we held our PPTG business meeting at the HFES annual meeting. In this newsletter, we would like to inform you about what we discussed and give some insights in the direction we would like to go as the perception and performance technical group.
Our PPTG Chair Jason McCarley gave a brief insight into the PPTG status. We are glad to conclude that we have a healthy financial position, which allows us to continue supporting students and early career professionals and organizing PPTG meetings. During the pandemic, our member numbers dropped quite significantly, but this year we've already seen a small recovery. We're now slightly above 200 members and hope to grow even more.
During our meeting, we presented the 2022 PPTG student award. Out of six excellent papers, our reviewers unanimously selected Colleen Patton's article "A Multiple Resource Examination of Time Sharing Performance for Egocentric and Allocentric Frames of Reference" as the winning paper. Please take the time to read her brief introduction and description of the work at the end of this newsletter. On behalf of our TG I would like to congratulate Colleen Patton again on this achievement. We invite students to prepare a paper for next year's student paper award again. We will review the paper on (i) scientific substance/impact of the work, (ii) quality of writing, and (iii) the student's contribution to work.
To further support our students, we would like to draw your attention once again to our PPTG Student Research Grant. We will provide two $500 grants for HFES student members to conduct independent research related to perception and performance. Please send a structured proposal to the PPTG Chair Jason McCarley by October 28, 2022. Questions regarding this grant can also be sent to Jason.mccarley@oregonstate.edu.
During our business meeting, we as a community concluded that we would like to further exchange knowledge on (i) perception research technologies, such as eye-tracking, (ii) perception support technologies, such as haptic feedback, (iii) human perception characteristics, such as visual impairment and auditory aspects of perception, and (iv) types of information presentation to improve understandability of information and/or to improve task performance. We would like to invite you all to prepare research papers on these topics for our annual meeting next year. If there is sufficient interest in these topics, we will try to organize an eye-tracking session, for example, next year in which we can exchange knowledge among different research domains.
Finally, we would like to draw your attention to our communication channels. You can find us and send those interested in our group to http://hfes-pptg.org/. Besides HFES Connect, we also use our Facebook and LinkedIn groups to inform you in a way that suits your personal preferences best. Please join us at https://www.facebook.com/groups/hfespptg/ and/or https://www.linkedin.com/groups/13561732/
We enjoyed meeting you all during our PPTG business meeting and technical sessions and are already looking forward to your contributions next year. Please do not hesitate to contact us if there is anything in which we can help you to enjoy your PPTG membership further.

I am Colleen Patton, a 4th year PhD student at Colorado State. I am so honored to have received this award for my work. As my first single author paper, it holds a special place in my heart and this award certainly makes it feel even more exciting! This paper would not have been possible without a number of other people along the way. To my advisors, Dr. Ben Clegg and Dr. Chris Wickens, my fellow graduate students in our lab, and the countless other colleagues that have helped me along the way - thank you for your mentorship, patience, and unwavering support. I am so excited to see where the P&P research is headed, and I feel grateful to be a part of it!
Paper abstract:
A Multiple Resource Examination of Time Sharing Performance for Egocentric and Allocentric Frames of Reference
Egocentric and allocentric frames of reference (FoR) can both be used in navigation aids, but each has benefits and drawbacks. Incorporating both FoR could be beneficial for offsetting the drawbacks of each viewpoint, but research on the timesharing ability of these FoR is lacking. The current study investigated whether FoR ought to be regarded as separate pools of cognitive resources under the framework of the Multiple Resource Model (MRM). In a dual task paradigm, results indicated that performance improved when both tasks used the same frame of reference. Such findings imply frames of reference are not separate pools in a multiple resources sense. Improved performance may be a result of task similarity, which can improve performance according to the shared processing routines hypothesis. Implications are discussed, including those for navigation aid design.
