Abstract

Professionals such as public safety workers have to use communication devices as part of their job which can be high stress and involve demands on their cognitive resources that would be better applied to their task at hand. Multi Modal User Interfaces (MMUI), have been proposed as a way of supporting more flexible, efficient interfaces, appropriately conveying information to users whilst they are busily involved in their tasks. In this paper we describe a usability study dealing with two types of MMUI environments, redundant and complementary, under a controlled driving simulation environment and explore how these two approaches plus increasing modality impacts user interactions with their primary task of driving plus their secondary task of communicating.
Results show that increasing modalities potentially help users communicate more effectively in high stimuli environments though modality conflict has to be considered when the user cannot ignore it e.g. audio instructions on driving whilst talking to someone. Whilst complementary modalities show a slightly higher cognitive load rating, in general there appears little difference between redundant and complementary approaches.

Abstract

This study aims to evaluate the usability of new Kansei navigation system interface features versus. existing interface design features in automotive navigation system. The Study population consist of participants which are chosen using purposive sampling technique consist of male professional drivers (PD) and non-professional drivers (NPD) of a local University in Malaysia. A total of 60 participant ranging from 18 – 39 years old participated in this study. Participants were tested using a customized driving simulator which participant will drive according to the route shown by the GPS navigation system( GPS system based on Kansei versus existing system) drivers were tested in terms of their 1) completion time for each task given 2) the number of error produce from each task 3) the satisfaction level from each feature in the GPS system using System Usability Scale (SUS) 4) a kansei survey to measure participant understanding and perception towards usability of GPS interface designs. 

A Counterbalance method was used in order to eliminate order biased participant. A total of 10 minutes was taken to complete the overall task. Wilcoxon Sign Test was used to compare all objectives except for satisfaction level for NPD and Kansei survey for PD.The Result for driving completion time for both PD and NPD, shows that Kansei GPS system (PD, mean = 2.49±0.66 min, NPD, mean = 2.18±0.71 min) had significantly shorter completion time (p=0.013) compared to the existing system (PD, mean = 2.75±0.66 min, NPD, mean = 2.44±0.74 min). For the number of errors, Kansei GPS system showed a significantly lowered driving error (p <0.05) (PD, mean = 8.86±6.55, NPD, mean = 7.23±6.03) compared to existing GPS System (PD, mean = 13.7±7.94 NPD, mean =10.6±7.6). For the satisfaction level showed no significant different in satisfaction for Kansei GPS System both (PD, mean score = 61.7±19.4 NPD, mean score = 66.58±21.9) compared to existing GPS (PD, mean score = 66.58±21.9 NPD, mean score = 63.58±20.9) (p>0.05). In term of Kansei Survey, shows that there is a significantly higher scoring for Kansei GPS system for both (PD, mean score = 3.6±0.99 and NPD, mean score = 3.69±1.44) compared with existing (PD, mean score =3.15±0.88 NPD, mean score = 2.68±0.18) (p<0.05). 

The conclusion of the was the new Kansei GPS system performed better in reducing the task completion time, reducing the numbers of driving error and easily distinguish features compared to existing GPS system. However, both professional and non-professional were satisfied using Kansei and existing GPS system.

Abstract

Driving is defined as a process of moving from one destination to another with the main aim to get to the destination safely. This study proposes a computational situation awareness model to assist drivers in effective performance of action based on his decision. The model incorporates cognitive factors that will influence action performance (yes/no) of the driver. To illustrate the proposed model, simulation scenarios based on overtaking maneuvers has been conducted. The experimental results show that the external factors attention and expectation have contributed to the effect on the safe and risky driving behavior and by suggestion on the driver’s action to perform the overtaken maneuvers based on his decision. Moreover, this model has been verified using an automated verification tool by checking its traces with the existing results from the literature.
