AbstractThis case study examines the methods used to troubleshoot a cochlear implant processor via video visit with a nonagenarian (90+ years old) with a bimodal cochlear implant system. This article will discuss the evaluation and management as well as which specific issues could be addressed virtually and how they were resolved. Examples will be provided about how to virtually connect with the patient and how to best facilitate communication during a video visit. Additionally, this article will examine the captioning apps and other hearing assistive technology available for smartphones that can provide further assistance during a cell phone call along with their benefits and limitations.

This paper carries out an analysis of various trade-in programs available for cellphones in the United States. Product trade-in is one of the methods to recover End-of-Life (EoL) products from consumers. Currently, there is a lack of knowledge amongst consumers about such programs. The study aims to determine the factors which influence the product trade-in price. Cell phone trade-in programs of the following types of companies are studied: Phone network operator, online retailer and recycler, and educational institution. Apple’s iPhone was selected to carry out a case study to analyze various features of the trade-in programs. Age of the cell phone model, memory size of the phone, cellphone condition and phone carrier were found to be the most significant factors of a cell phone trade-in program. Newer phone models and higher memory size capacity phones were found to be offered higher price to the consumer. Cellphones of one particular phone carrier and unlocked cell phones were found to obtain the highest price quote. An attempt is made to evaluate and discuss the prospect of trade-in programs as an effective end of life recovery method. Product recovery by trade-in programs and conventional methods is compared based on factors drawn from consumer behavior studies. Improvements in trade-in programs are suggested, followed by a discussion on ways in which data from trade-in programs can benefit product designers.

Abstract Over the past 20 years, there have been many advances in the computer industry as well as in augmentative and alternative communication (AAC) devices. Computers are becoming more compact and have multiple purposes, such as the iPhone, which is a cell phone, mp3 player, and an Internet browser. AAC devices also have evolved to become multi-purpose devices; the most sophisticated devices have functionality similar to the iPhone and iPod. Recently, the idea of having the iPhone and iPad as a communication device was initiated with the development of language applications specifically for this format. It might be true that this idea could become the future of AAC devices; however, there are major access issues to overcome before the idea is a reality. This article will chronicle advancements in AAC devices, specifically on access methods, throughout the years, towards the transition to handheld devices. The newest technologies hold much promise with both features and affordability factors being highly attractive. Yet, these technologies must be made to incorporate alternate access if they are to meet their fullest potential as AAC tools.

This study used both cellular phones and analogue radio to measure driver distraction and workload in a low fidelity driving simulator. Thirty-four participants performed a simulated driving task while using either a cell phone or a radio in conjunction with a secondary task assessing their spare attentional capacity. The results showed that more lane deviations were made during the cell phone and radio tuning use than both of the pre-allocation and Post-allocation phases. The secondary task errors were also higher during both the cell phone and radio tuning allocation phase than the pre-allocation and post-allocation phases. These findings indicate the greater workload load levels associated with the use of telemetric devices. These findings have major implications for driver safety and telemetric systems design.
