The effects of signal modality (visual and auditory), hand condition (crossed and uncrossed), and head orientation (upright, right-90, left-90, and left back) on response performance were e xamined in this study. The results showed all the factors significantly affected the reaction time of participants and there was an interaction effect between signal modality and head orientation. Responses for visual signals were significantly faster than those for auditory signals, and responses made with uncrossed hand were superior to those with crossed hand. On head orientation, upright orientation produced the fastest reaction time, while reaction time for head rotated 90° right (right-90) was significantly faster than that for head rotated 90° left (left-90) and rotated left backward (left back). Regarding the significant interaction effect between signal modality and head orientation, processing time for visual signals was always faster than that for auditory signals. Such modality superiority increased to a larger extent under the left 90 and left back head orientations. The findings in this experiment provide some practical ergonomics recommendations for improving control console design in terms of signal-response layout, stimulus-hand arrangement, head orientation, and methods of presenting visual and auditory signals.

Budget-related decisions in search auctions are recognized as a structured decision problem, rather than a simple constraint. Budget planning over several coupled campaigns remains a challenging but utterly important task in search advertisements. In this paper, we propose a multi-campaign budget plan- ning approach using optimal control techniques, with consideration of the substitute relationship between advertising campaigns. A measure of coupled relationships between campaigns is presented, e.g., the over- lapping degree (O) in terms of campaign contents, promotional periods and target regions. We also discuss some desirable properties of our model and possible solutions. Furthermore, computational experiments are conducted to evaluate our model and identified properties, with real-world data collected from logs and reports of practical campaigns. Experimental results show that, (a) coupled campaigns with higher over- lapping degrees can reduce the optimal budget level and the optimal revenue, and also arrive the budgeting cap earlier;(b) The advertising effort could be seriously weakened when ignoring the overlapping degree between campaigns.
