Behavior Input DeviceJohn L. I actually found your post on https: However, the interesting thing is that when my bluetooth device goes to sleep, it appears that select returns with descriptor in the read array. So interestingly, it seems that it takes a while Behavior Input Device udev to actually tell me that the device is gone so that I can tear down the fd in the selected set.


I dealt with this by just doing an os. Behavior Input Device participants divided attention as directed, their performance should change according to the amount of attention directed to the video game task Behavior Input Device those scores should be similar across devices within each attention condition. As shown in Figure 2participants were able to change the amount of effort allocated to the video game task; that is, scores were better when more attention was devoted to the task. These data suggested participants allocated their attention as instructed and both device groups followed instructions similarly.

For example, it was not the case that direct device users followed our attention allocation instructions differently than indirect device users. Analysis to determine if participants distributed attention as instructed. Scores were converted Behavior Input Device z-scores Behavior Input Device show relative performance of older and younger adults. Standardized scores are presented for each attentional allocation condition. Bars represent standard error.

There were two main questions of interest pertaining to the match between the task demands and the device characteristics. First, does a match between input device and task demands predict performance with a device? Response time for input tasks was the chosen measure of performance. The results showed match or mismatch did impose relatively different attentional demands that interacted with both age and attention allocation. We assessed performance for four input requirements that differed in whether the task demands matched the characteristics of the input device. Pointing Behavior Input Device and ballistic tasks were presumed to be best suited to the touch screen whereas the repetitive tasks and precision tasks were expected to be better matched to the rotary encoder.

We were interested in the relative speed with which these Behavior Input Device were performed when there was a match or mismatch with input device. Thus, z-scores were computed using the grand mean across attentional conditions, input requirements, and age groups.

In general, when less attention was available, response times increased. However the response times of Behavior Input Device adults in a mismatched situation increased differentially compared to those using an input device matched to the task Figure 3.

Graphical analysis of the importance of a match between device characteristics and task demands as a function of attention for younger and Behavior Input Device adults. Thus the match between task demands and input device features does seem to be important.

Behavior Input Device Younger adults may be better able to compensate for a mismatch, even when their attention was divided. However, older adults benefited from a match between device and task as soon as their attention was divided, and their need for a match increased as less attention was available for the task. In sum, using input devices clearly required attention. Withdrawal of attention had the Behavior Input Device impact for older adults and especially when they were using an input device mismatched to the input requirements.


The central Behavior Input Device of this research related to the attentional demands of input devices and how those demands are moderated by input requirements and user age. The results showed that using an input device required attention and the demands on attention were greater for a mismatch of device and input requirements, for older adults relative to younger adults, and the most attention was demanded from older adult users using a device mismatched to the input requirements. We directly controlled and tested the concept of a match or mismatch between device and input requirements put forth by Rogers et al. This produced observable functions in performance that depended on available attentional resources. The differential difficulty experienced by older adults in a mismatch scenario provided evidence of an attentional cause, and was further supported by their increasing response times as less attention was available, compared to using a device matched to the input requirements.

The main characteristics that describes the logical behavior of an input device: 1) what measurements the device returns to the user program, and. 2) when the.
