Haptic perception of users with low vision and their needs in haptic-incorporated user interfaces

Area of Science:

• Human-Computer Interaction
• Accessibility Research
• Haptic Technology

Background:

• Understanding the haptic capabilities and needs of users with low vision is crucial for designing inclusive user interfaces.
• Previous research has not fully explored the similarities and differences in haptic perception and interface requirements between sighted users and those with low vision.

Purpose of the Study:

• To investigate and compare the haptic perception and user interface needs of individuals with low vision and sighted individuals.
• To inform the design of haptic-incorporated user interfaces that cater to a diverse user base.

Main Methods:

• Study 1 utilized magnitude estimation to compare haptic perception between sighted participants and participants with low vision.
• Study 2 assessed the degree of similarity in user interface needs between the two vision groups.

Main Results:

• No significant differences were found in haptic perception or general user interface needs between sighted individuals and those with low vision.
• Some variations in specific user interface preferences were observed, highlighting the need for careful design considerations.

Conclusions:

• The findings suggest that haptic capabilities and user interface needs are largely comparable across sighted individuals and those with low vision.
• Universal design principles, incorporating a range of haptic feedback, can accommodate preferences of both groups, leading to more successful product development.
