Episode #28The Fringe #461

Ian R Buck makes an audio adaptation of his senior seminar paper from 2015.

Episode Summary

00:00 | Intro

00:54 | Abstract

In an increasingly connected, mobile world, situations where users do not interact with their digital lives are becoming few and far between. This can be a problem in situations that demand a user's attention for their safety. Driving is one such situation, and it is doubly important because a significant portion of the western population drives on a daily basis. Researchers have tested different interface designs with the goal of finding one that demands the least cognitive load while still allowing the user to perform the desired task efficiently. In this paper interfaces incorporating auditory cues, voice dictation, and air gestures are discussed.

04:01 | 2.1.1 Touchscreens

04:56 | 2.1.2 Voice Dictation

05:37 | 2.1.3 Screen Reading

06:50 | 2.1.4 Air Gestures

07:25 | 2.2 Testing Distracted Driving

08:11 | 2.2.1 Lane Changing Exercise

08:44 | 2.2.2 Car Following Exercise

09:25 | 2.2.3 Eye Tracking

09:55 | 3. Auditory Cues

Figure 1, Mean time eyes on driving chart
Figure 1: Mean time visual fixation on the primary task. The control was significantly higher than all other conditions. Spindex+TTS was significantly higher than no sound and spearcon+TTS, marked here with dots.

14:15 | 4. Text-To-Speech and Voice Dictation

Figure 2a, Mean lateral deviation
Figure 2a: Mean lateral deviation during responding phase. Overall using the single TTS voice resulted in lower deviation than matching TTS voices.
Figure 2b, Mean lane change initiation
Figure 2b: Mean lane change initiation during responding phase. Using single TTS voice resulted in faster reaction times than matching TTS voices, but the difference was not significant.
Figure 3, Mean e-mail comprehention
Figure 3: Email comprehension. Matching TTS voices had much higher comprehension than single TTS voice for low complexity messages.
