Using an Extended Automatic Target Acquisition Program with Dual Cursor technology to assist people with...

Area of Science:

• Assistive technology
• Human-computer interaction
• Developmental disabilities research

Background:

• Traditional Automatic Target Acquisition Programs (ATAP) improve pointing performance but have limitations, such as inability to utilize mouseover effects.
• Mouseover effects require the cursor to be directly over the target, posing a challenge for some users.

Purpose of the Study:

• To evaluate the effectiveness of a Dual Cursor Automatic Target Acquisition Program (DCATAP) in improving pointing performance.
• To address the limitations of existing ATAP by incorporating features that overcome the mouseover effect constraint.
• To assess the impact of DCATAP on the speed, ease, and accuracy of target positioning for children with developmental disabilities.

Main Methods:

• Two children with developmental disabilities participated in the study.
• Baseline sessions were conducted to establish initial pointing performance levels.
• Intervention sessions utilizing DCATAP were implemented, with staggered introduction for each participant.
• A maintenance phase was included to assess long-term performance improvements.

Main Results:

• Participants demonstrated significant improvements in pointing performance after the intervention.
• The DCATAP facilitated quicker, easier, and more accurate target positioning.
• Performance gains were sustained during the maintenance phase.

Conclusions:

• DCATAP effectively enhances pointing performance for individuals with developmental disabilities.
• The program overcomes ATAP's limitations, offering a more versatile assistive technology solution.
• DCATAP shows promise for improving computer interaction accessibility and efficiency.
