Understanding customers' holistic perception of switches in automotive human–machine interfaces

For successful new product development, it is necessary to understand the customers' holistic experience of the product beyond traditional task completion, and acceptance measures. This paper describes research in which ninety-eight UK owners of luxury saloons assessed the feel of push-switches in five luxury saloon cars both in context (in-car) and out of context (on a bench). A combination of hedonic data (i.e. a measure of ‘liking’), qualitative data and semantic differential data was collected. It was found that customers are clearly able to differentiate between switches based on the degree of liking for the samples' perceived haptic qualities, and that the assessment environment had a statistically significant effect, but that it was not universal. A factor analysis has shown that perceived characteristics of switch haptics can be explained by three independent factors defined as ‘Image’, ‘Build Quality’, and ‘Clickiness’. Preliminary steps have also been taken towards identifying whether existing theoretical frameworks for user experience may be applicable to automotive human–machine interfaces

Customer perception of switch-feel in luxury sports utility vehicles

Successful new product introduction requires that product characteristics relate to the customer on functional, emotional, aesthetic and cultural levels. As a part of research into automotive human machine interfaces (HMI), this paper describes holistic customer research carried out to investigate how the haptics of switches in luxury sports utility vehicles (SUVs) are perceived by customers. The application of these techniques, including an initial proposal for objective specifications, is addressed within the broader new product introduction context, and benefits described. One-hundred and one customers of SUVs assessed the feel of automotive push switches, completing the tasks both in, and out of vehicles to investigate the effect of context. Using the semantic differential technique, hedonic testing, and content analysis of customers’ verbatim comments, a holistic picture has been built up of what influences the haptic experience. It was found that customers were able to partially discriminate differences in switch-feel, alongside considerations of visual appearance, image, and usability. Three factors named ‘Affective’, ‘Robustness and Precision’, and ‘Silkiness’ explained 61% of the variance in a principle components analysis. Correlations of the factors with acceptance scores were 0.505, 0.371, and 0.168, respectively

Investigating the Features of the M170 in Congenital Prosopagnosia

Face perception generates specific neural activity as early as 170 ms post-stimulus onset, termed the M170 when measured with Magnetoencephalography (MEG). We examined the M170 in six people with congenital prosopagnosia (CP) and 11 typical controls. Previous research indicates that there are two neural generators for the M170 (one within the right lateral occipital area - rLO and one within the right fusiform gyrus - rFG), and in the current study we explored whether these sources reflect the processing of different types of information. Individuals with CP showed face-selective M170 responses within the rLO and right rFG, which did not differ in magnitude to those of the controls. To examine possible links between neural activity and behavior we correlated the CPs' MEG activity generated within rLO and rFG with their face perception skills. The rLO-M170 correlated with holistic/configural face processing, whereas the rFG-M170 correlated with featural processing. Hence, the results of our study demonstrate that individuals with CP can show an M170 that is within the normal range, and that the M170 in the rLO and rFG are involved in different aspects of face processing

The Trans-Pacific Partnership (TPP): Negotiations and Issues for Congress

The Trans-Pacific Partnership (TPP) is a potential free trade agreement (FTA) among 12, and perhaps more, countries (Figure 1). The United States and 11 other countries o f the Asia-Pacific region—Australia, Brunei, Canada, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore, and Vietnam—are negotiating the text of the FTA. With over 20 chapters under negotiation, the TPP partners envision the agreement to be “comprehensive and high-standard,” in that they seek to eliminate tariffs and nontariff barriers to trade in goods, services, and agriculture, and to establish or expand rules on a wide range of issues including intellectual property rights, foreign direct investment, and other trade-related issues. They also strive to create a “21st-century agreement” that addresses new and cross-cutting issues presented by an increasingly globalized economy. The TPP draws congressional interest on a number of fronts. Congress would have to approve implementing legislation for U.S. commitments under the agreement to enter into force. In addition, under long-established executive-legislative practice, the Administration notifies and consults with congressional leaders, before, during, and after trade agreements have been negotiated. Furthermore, the TPP will likely affect a range of sectors and regions of the U.S. economy of direct interest to Members of Congress and could influence the shape and path of U.S. trade policy for the foreseeable future. This report examines the issues related to the proposed TPP, the state and substance of the negotiations (to the degree that the information is publicly available), the specific areas under negotiation, the policy and economic contexts in which the TPP would fit, and the issues for Congress that the TPP presents. The report will be revised and updated as events warrant

The Trans-Pacific Partnership (TPP): In Brief

The Trans-Pacific Partnership (TPP) is a proposed free trade agreement (FTA) among 12 Asia-Pacific countries, with both economic and strategic significance for the United States. If approved, it would be the largest FTA in which the United States participates. The 12 countries announced the conclusion of the TPP negotiations on October 5, 2015, after several years of ongoing talks. The President released the text of the agreement and notified Congress of his intent to sign on November 5, 2015. Congress would need to pass implementing legislation for a final TPP agreement to enter into force for the United States. Such legislation would be eligible to receive expedited legislative consideration under the recent grant of Trade Promotion Authority (TPA), P.L. 114-26, if Congress determines the Administration has advanced the TPA negotiating objectives, and met various notification and consultation requirements. TPP negotiating parties include Australia, Brunei, Canada, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore, the United States, and Vietnam. Through the TPP, the participating countries seek to liberalize trade and investment and establish new rules and disciplines in the region beyond what exists in the World Trade Organization (WTO). The FTA is envisioned as a living agreement that will be open to future members and may become a vehicle to advance a wider Asia-Pacific free trade area. It is a U.S. policy response to the rapidly increasing economic and strategic linkages among Asian-Pacific nations and has become the economic centerpiece of the Administration’s “rebalance” to the region. The TPP has slowly evolved from a more limited agreement among four countries concluded in 2006 into the current 12-country FTA agreement, with the United States joining the negotiations in 2008. Japan, the most recent country to participate, joined the negotiations in 2013. This significantly increased the potential economic significance of the agreement to the United States, because Japan is the largest economy and trading partner without an existing U.S. FTA among TPP negotiating partners (thus having greater scope for trade liberalization with the United States). The United States already has FTAs with 6 of the 11 other countries participating. Malaysia and Vietnam also stand out among the TPP countries without existing U.S. FTAs, given the rapid growth in U.S. trade with the two nations over the past three decades and substantial presence of state-owned enterprises (SOEs) that will be affected by the TPP’s SOE provisions. Views on the potential impact of the agreement vary. Proponents argue that the TPP has the opportunity to boost economic growth and jobs through expanded trade and investment opportunities with negotiating partners that currently make up 37% of total U.S. goods and services trade, involves writing new trade rules and disciplines, and deepening U.S. trade and investment integration in what many see as the world’s most economically vibrant region. The agreement would eventually eliminate all tariffs on manufactured products and most agricultural goods. It also includes new trade disciplines on issues such as digital trade barriers, state-owned enterprises (SOEs), and regulatory coherence, among other provisions. Opponents voice concerns over potential job loss and competition in import-sensitive industries, and how a TPP agreement might limit U.S. ability to regulate in areas such as health, food safety, and the environment, among other concerns. The Obama Administration, joined by many analysts as well as many policymakers in the region, has argued that the strategic value of a potential TPP agreement parallels its economic value, contending that the agreement would strengthen U.S. allies and partners and reaffirm U.S. economic leadership in the region. The President has repeatedly highlighted the importance of maintaining U.S. leadership in crafting global trade rules, notably with reference to potentially alternative Chinese initiatives. China is not a party to the TPP. Others argue that past trade pacts have had a limited impact on broad foreign policy dynamics

Investigating soil property and quality changes from samples submitted to the LSU AgCenter Soil Testing Laboratory

The primary purpose of the study is to investigate the trends in soil nutrient levels from soil samples submitted to the LSU AgCenter soil testing and plant analysis laboratory during 2008 to 2012. This study indicates the trend for soil pH, soil phosphorus and soil potassium for corn, cotton, rice, grain sorghum, soybeans, and sugarcane. These six crops were analyzed in this study because of the economic significance to the Louisiana agricultural industry. The trend in soil nutrients studied were generally within the recommended levels for sustainability and environmental stewardship. This study describes the trends for soil pH, soil phosphorus and soil potassium for Louisiana soils during the years 2008 – 2012. The value of this paper lies in calling attention to broad nutrient needs and challenges faced by the crop producers. Finally, the study findings demonstrate the importance of monitoring soil nutrient trends and environmental stewardship

Bone-to-bone and implant-to-bone impingement : a novel graphical representation for hip replacement planning

Bone-to-bone impingement (BTBI) and implant-to-bone impingement (ITBI) risk assessment is generally performed intra-operatively by surgeons, which is entirely subjective and qualitative, and therefore, lead to sub-optimal results and recurrent dislocation in some cases. Therefore, a method was developed for identifying subject-specific BTBI and ITBI, and subsequently, visualising the impingement area on native bone anatomy to highlight where prominent bone should be resected. Activity definitions and subject-specific bone geometries, with planned implants were used as inputs for the method. The ITBI and BTBI boundary and area were automatically identified using ray intersection and region growing algorithm respectively to retain the same ‘conical clearance angle’ obtained to avoid prosthetic impingement (PI). The ITBI and BTBI area was then presented with different colours to highlight the risk of impingement, and importance of resection. A clinical study with five patients after 2 years of THA was performed to validate the method. The results supported the study hypothesis, in that the predicted highest risk area (red coloured zone) was completely/majorly resected during the surgery. Therefore, this method could potentially be used to examine the effect of different pre-operative plans and hip motions on BTBI, ITBI, and PI, and to guide bony resection during THA surgery

The role of cervical spine range of motion in recovery from whiplash associated disorders

This thesis investigates the role of cervical spine Range of Motion in the recovery from Whiplash Associated Disorders. In clinical practice, Health Care Professionals attach value to measurements of cervical spine Range of Motion for diagnostic, prognostic and treatment evaluation purposes. A systematic literature review found conflicting evidence as to whether cervical spine Range of Motion was a prognostic factor following a whiplash injury. Greater understanding of prognostic factors such as this may facilitate improvements in patient management. A second systematic literature review investigated the reliability and validity of methods for measuring cervical spine Range of Motion. The Cervical Range Of Motion (CROM) device was found to be the most rigorously tested and clinimetrically promising method and was subsequently investigated for intra- and inter-observer reliability in a group of whiplashinjured individuals and found to be substantially reliable. The CROM device was utilised in a longitudinal cohort study of 599 whiplash-injured patients to investigate the prognostic value of cervical spine Range of Motion for neck painrelated disability and patient-reported recovery at short, medium and long-term follow-up. A patient-reported version of cervical spine Range of Motion was also evaluated as a prognostic factor. Although useful for explaining disability at the time of measurement, active, passive and patient-reported forms of cervical spine Range of Motion were not significant prognostic factors for poor outcome when other physical and psychosocial factors were accounted for. The clinical implication of this research is that if patients are experiencing reduced cervical spine Range of Motion a few weeks after their whiplash injury they will not necessarily have a poor outcome in the longer term as is commonly believed at present
