"Mango Mango, How to Let The Lettuce Dry Without A Spinner?'': Exploring User Perceptions of Using An LLM-Based Conversational Assistant Toward Cooking Partner
The rapid advancement of the Large Language Model (LLM) has created numerous
potentials for integration with conversational assistants (CAs) assisting
people in their daily tasks, particularly due to their extensive flexibility.
However, users' real-world experiences interacting with these assistants remain
unexplored. In this research, we chose cooking, a complex daily task, as a
scenario to investigate people's successful and unsatisfactory experiences
while receiving assistance from an LLM-based CA, Mango Mango. We discovered
that participants value the system's ability to provide extensive information
beyond the recipe, offer customized instructions based on context, and assist
them in dynamically planning the task. However, they expect the system to be
more adaptive to oral conversation and provide more suggestive responses to
keep users actively involved. Recognizing that users began treating our LLM-CA
as a personal assistant or even a partner rather than just a recipe-reading
tool, we propose several design considerations for future development.Comment: Under submission to CHI202
Webâbased Weight Management Programs in an Integrated Health Care Setting: A Randomized, Controlled Trial
Objective : To assess the efficacy of a Webâbased tailored behavioral weight management program compared with Webâbased informationâonly weight management materials. Research Methods and Procedures : Participants, 2862 eligible overweight and obese (BMI = 27 to 40 kg/m 2 ) members from four regions of Kaiser Permanente's integrated health care delivery system, were randomized to receive either a tailored expert system or informationâonly Webâbased weight management materials. Weight change and program satisfaction were assessed by selfâreport through an Internetâbased survey at 3â and 6âmonth followâup periods. Results : Significantly greater weight loss at followâup was found among participants assigned to the tailored expert system than among those assigned to the informationâonly condition. Subjects in the tailored expert system lost a mean of 3 ± 0.3% of their baseline weight, whereas subjects in the informationâonly condition lost a mean of 1.2 ± 0.4% ( p < 0.0004). Participants were also more likely to report that the tailored expert system was personally relevant, helpful, and easy to understand. Notably, 36% of enrollees were AfricanâAmerican, with enrollment rates higher than the general proportion of African Americans in any of the study regions. Discussion : The results of this large, randomized control trial show the potential benefit of the Webâbased tailored expert system for weight management compared with a Webâbased informationâonly weight management program.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/93691/1/oby.2006.34.pd
Adaptive Health Coaching Technology for Tailored Interventions
Recent advances in sensor and communications technology have enabled scalable methods for providing continuity of care to the home for patients with chronic conditions and older adults wanting to age in place. In this article we describe our framework for a health coaching platform with a dynamic user model that enables tailored health coaching messages. We have shown that this can improve coach efficiency without a loss of message quality. We also discovered many lessons for coaching technology, most demonstrating the need for more coach input on sample message content, perhaps even requiring that individual coaches be able to modify the message database directly. Overall, coaches felt that the structure of the automated message generation was useful in remembering what to say, easy to edit if necessary and especially helpful for training new health coaches
